Probably better to make a note of it. "annotation" is marginal or footnote entries in a book that go into detail on a highlighted subject. "Notation" is a noun that means the act of taking notes. "Making a note" is writing down a concept once to be reviewed later. "Notate" is not a word. A person doesn't "Notate" something. They "note" it or "note it down."
Dr. C is one of those people that could say "I'm going to talk about random shit for an hour." and I'd sit down and listen. Perfect voice and charisma for being a speaker.
As much as I love the usual HT for making its points really solidly, many of us trust this channel for good info by now and this Q&A format covers a lot more ground in a more entertaining style. More of these or a Healthcare Triage podcast every so often would be really cool.
Alan Gebhardt Good idea!!! HCT Podcast! I'd have it in my daily subscription along with Planet Money, Freakonomics, Intelligence Swuared, and 99% Invisible.
As a personal fitness trainer I always told my clients that they should skip the supplements until they reach a point where they are sleeping good every night, eating very healthy every day, and training intensely 5-6 days a week without compromise, and they feel they need to aid their body in coping with their intense training. Not as some kind of magic pill, so they can skip workouts, not put forth the effort, eat like unsupervised children, and still swell like Arnold.
***** Ah, but what exactly is being warmed up? Our internal body temperature doesn't change all that much, and when it does that's usually a bad thing (ie fever). Not to mention, what is the difference between stretching in advance and muscles being used during exercise? How does doing it in advance change anything? When you think about it, stretching doesn't really make that much sense.
Taking things with a grain of salt here; just because there is no (statistical) data that shows both to be beneficial, it doesn't mean it always isn't. I like to think of "warming up" and stretching as two separate things. Warming up can be anything like running or doing some exercises, which can exert the body just as much as whatever activity is performed afterwards. Stretching however, so long as you don't go overboard to stretch until you feel pain; WILL benefit you from straining muscles too hard later, especially before swimming. Don't want to get a leg cramps and drown in the ocean? Stretch. What happens to clothes of certain fabrics after they're washed and hung to dry? Unless you lightly stretch them out while damp/wet, over time they shrink, and shrink, to the point you feel like it's a size smaller. The same can apply to muscles. Long story short: everything in moderation.
Jake Hayes But I have noticed that if I don't stretch before martial arts practice, I can't kick as high, punch as fast, or run as fast. I don't believe it's a coincidence.
On the stretching thing: it's important to note that he is talking about stretching before physical activity. In all honesty the best way to look at stretching is as another form of physical exertion. Obviously not an aerobic form. But stretching can be beneficial if done in a separate "work out" so that your muscles lengthen. Which is definitely good if your muscles are overly tight, pulling when you don't want them to.
Absolutely yes to the nutritional supplement answer- expensive pee. To the stretching- dynamic stretching before exercise prevents injury. Static stretching would not. Please be sure to specify the difference! Such a huge fan of this channel! :)
A friend smokes; however, he also exercises regularly and he believes that by continuing to be active; exercising the organs prone to carcinogens (heart, lungs, etc.) that he might be offsetting some of the damage caused by smoking? I have to admit; the guy works out hard; heavy cardio / Vo2-Max training /Road Cycling (20miles/day); and seems to be in good shape; even dives for abalone and can stay under water a lot longer than I can. But, this just seems like something a smoker tells himself to continue smoking - a professional opinion would be helpful to educate him (or myself?). Thanks - love the shows!!
Direct feedback! I really liked this format. Aaron is much more engaging/lovable when he's interacting with a person right next to him. Also, I continually appreciate your "the sky isn't falling" approach: helps us focus on the real things, e.g. regular exercise.
I only have one wish for this show. Whenever you mention a study/studies show, I kinda want them sourced, like links to those studies (hopefully somewhere on the screen) so I can look at them myself. I understand that this might logistically difficult. You are an expert I trust, I need that trust to be verified. Great show.
This is probably one of my favorite HealthCare Triage videos yet. Dont' get me wrong, I love all these videos, but this one had a lot of good information packed into a single segment. Keep it going, we're listening.
I absolutely love this channel! I'm always the one telling people to look up the studies. I hate hearin, "They say you should do X, or Y." My first question is, "who says that?" I always push people to look at the studies, the evidence, see what they say. And I love that this channel dives fully into that. If I could cuddle up with this channel, I would.
Very informative! I watched it straight through to the end. I'm so glad this channel exists because it's nearly impossible to get unbiased and accurate information from someone who truly knows what they're talking about. Keep doing what you do! :) it's great.
My English teacher brought up the study about Oreos and cocaine in class and was totally invested in the idea that Oreos were as addictive than cocaine.
As a nutrition student, I found the mix up between HDL and LDL disturbing, especially since the correction was in the description at the bottom. HDL is the so called "good" cholesterol and LDL the "bad" cholesterol. Although you are right, food consumption does not alter either (but exercise does!). Also, many people at many geographical locations would benefit from a vitamin D supplement in the winter.
How did the the highschool/college students get the cocaine? I mean there's the obvious drug dealer path, but how would they get that published? And who knew the guy who has a drug dealer? And if they got it legally somehow, who was monitoring everything? SO MANY QUESTIONS!!!
If you're researching addictive behavior, you can legally get addictive agents. As for who monitors it (besides their research supervisor, of course), I would assume the FDA and possibly the DEA.
Mallinckrodt Pharmaceuticals can legally make cocaine in the United States, but I'm not sure if they're alone. I mean Pharmaceutical companies usually have access to many illicit drugs. They likely buy from Peru, where it is semi-legal to farm coca plants (although I'm sure other countries have fields for medical/research purposes). So my guess is that Universities gain access through Pharmaceutical companies for research purposes.
My confidence in everything you said went out the window when you got HDL and LDL mixed up.... Guess I'm going to have to go back to webMD to quench my need for medical advice/information.
Yes because off the cuff guesses are just as reliable as when they spend a week writing and researching a episode. It's not like one doctor can have everything in medical science in his brain and on speed dial.
I like Aaron's casual style here better than the accusative style of most other videos. _Having said that_, I do find these video's very interesting and informing. Keep up the good work!
I glad you made the distinction between multivitamins and supplements. Some people act like it's crazy to take multivitamins as well, whereas it seems kind of obvious that if your body is a little low on something it can get it from the multivitamin whereas taking huge amounts of individual vitamins is just going to cause you to pee them out.
My understanding of the stretching thing is this: When you stretch, it does more to separate the muscle fibers. Kinda like "ripping" though muscles don't actually "rip". But in either case, when you go to exercise, if 10% of your muscle is "ripped", then the force is focused on the remaining 90% and thus you perform worse, gain less, and are at more of a risk for injury. The main benefit I can think of is avoiding tendon damage due to lack of flexibility. But in that case, you can do something like yoga at any time to get the same benefit.
In regards to the satisfaction question, I find that very true. My sister was going through a stressful time in her life but was not suffering from any mental illness like anxiety, but her doctor still gave her anxiety medication so she left there happy.
From a professional sports career (climbing) and a heavy training (gymnastics) what I can tell in favor of stretching after the effort is that it increses flexibility which is important since heavy exercise WITHOUT stretching decreases it pretty fast. Yet, I have but 10+ years of experience witnessing that so I don't know to what extent this is exact or only applying to me.
Oh! You were doing so good until 6:46 when you fell into the trap of associating body size with diet. It is a commonly held misconception that you can tell a person's diet by looking at them. Turns out, looking at somebody doesn't provide that information.
The things we say, even conversationally, inform and impact our thinking and beliefs. In this context: an expert speaking in an informational video, it is especially important that casual phrasing not support bad thinking and unsupported but common beliefs. I think Dr. Carroll agrees that you can't tell a person's diet by looking at them, so that is why I suggested he not say it, even conversationally. Because that belief is actually held by many people and can be quite hurtful when expressed.
I learned from my doctor that HDL is good and you want it to be high (they both start with "H"). LDL is bad and you want it to be low (both start with "L").
Some pretty mindblowing info in here! Thanks. I shared it on facebook. My fitness buff brother will probably dispute some of the facts. Let me ask so that I know when he brings it up: when you say nutritional supplements don't make a difference, does that mean drinking protein shakes or eating protein bars doesn't help build muscle? Is that what was implied in the conversation about John's guns? Thanks in advance!
Aaron I don't understand your hoodie. Why are there so many zippers? Why are they all vertical? Why is one silver and the others black? Why does healthcare make more sense then that hoodie?
Correction, at about 9:30. LDL is the bad cholesterol. HDL is good cholesterol. Low density proteins are big and chunky and cause blockages, High Density proteins are all smushed up and kinda just do their own thing regardless of your clotting factors. VLDL is the worst though, Very Low Density Lipoprotein.
this has been the most entertaining interview, Q&A (or what ever you call this) on youtube. i've learned a lot and laughed a lot. you guys are awesome!
11:00 disagree - they WERE actually talking about eight hours of continuous sedentary behavior (i.e. stuck in a cubicle) increasing risk for CVD, not exercise. most people don't actually do that unless they never leave their desk even for lunch, but IIRC, that was the point they were making.
10:59 - I remember that study and that's not what they said. As John mentions, they specifically noted that men (it was exclusively men in the study) that exercised regularly were just as likely to have cardiovascular disease as those who never exercised when both were sitting more than 4 hours a day. Exercise did not reduce their chance of heart attack.
Stretching is important, but not nearly so much before performance. More so after a hard workout so that you are not as stiff the next day. Also, stretching makes you more flexible over time. (Imagine that!) And that does eventually affect performance, obviously. It's just that a single stretch routine right before a particular performance will not have a noticeable effect on that performance.
Any chance you could elaborate on the bodybuilding stuff? Because other people seem pretty sure that protein + working out = muscles. I'd really like to hear your thoughts on it.
I *think* what he was talking about there were nutritional supplements, mostly. Like, getting more of various vitamins and stuff doesn't help with building muscle. I could be wrong though.
UnqualifiedAdvice Think so too but on the other hand he said protein shakes... And in short even bodybuilders don't need protein supps and especialy if they are not on juice. Why they exist? Well they help. A general rule of thumb is 2g of protein for 1kg of lean body mass per day. And that's the top end, some say it's less and some say it's more. you probably can ignore the ones who say it's more and test out if less is enough for you. You need protein for muscle development and IF you don't eat enough, than supplements might help. That's the same with supps in every part of the life. They only make sense if you are deficient in something, you should allways try to get your macro- and micro nutrions in through "real" food.
I think that the kind of protein (like creatin) you take doesn't really matter because your gastric acid contains pepsin that breaks apart any protein into amino acids. I imagine it could be beneficial to take proteins with amino acids that your body can't synthesize but if that isn't really significant i'd say eating any source of protein is about as good as the other and you don't really need creatin powder.
Teun van den Brand creatin works. That's one of millions supps that is actually tested in 100. of studies but it'll give you maybe 5% to 10% more strengh, not more. It's not any magic (also not protein).
Coming from being an athlete in college working out 30+ hours per week working out = muscles; protein = muscles get repaired at quickly as possible. Not having enough protein slows muscle repair. That being said, a balanced diet will provide all of the protein you need. Just don't eat a crappy diet.
Hey Aaron, could you elaborate more on the questions of vitamins and supplements impacting health? I am aware of a meta analysis in BMJ that showed considerable benefits to having sufficient levels of Vitamin D, and most patients (especially us high latitude folk) have insufficient levels so supplementation would be beneficial. What about Vitamin C prior to an operation or during cold/flu season? What about essential oils like Omega 3? I think there are a lot of misconceptions, but potentially some benefits as well to this topic. Love your talks, always good for sparking conversation. Thanks.
Really great video! I hope you'll continue making them! :) I'd love to hear more about the vitamin supplements. (yeah, I know, a simple "NO!" is great, but, atleast here in germany, there are so much contradicting statements)
You talked in previous episodes about healthcare in the us and canada. Which country do you think has the best healthcare system? Also how would New Zealand rate? On another note an episode on stretching would be nice
Strictly anecdotally, I find that warming up before exercise, like bodyweight squats, etc helps to loosen up the joints, decreasing pain during intense exercise, helping flexibility, and preventing sudden popping and moving of joints. Additionally, the joints that have problems are ones that I hurt as a teen, having torn ligaments or muscles or sprained.
not exactly, he said walking would be more beneficial than stretching because although there is not alot of evidence to support it, it at least makes sense because you start to move the lactic acid in your body. Again, it all depends on your definition of "warm up" personally, I would not categorize walking as such. I think he is speaking more of a warm up routine than a stroll around the block. I mean we are constantly walking anyways so why would it be considered a warm up exercise? I dunno, just doesn't make sense to me at least.
Jim Mulvaney Mentioning walking and "moving" lactic acid was mentioned as part of a cool down, not warm up, as in after strenuous exercise is completed. After repeat viewing, it could be construed that the term "warm-up" was used as a colloquial synonym for "stretch" merely to break the flow and prevent redundancy of terminology.
Well, as a fitness freak, I will say that "warm-up" exercises are a necessity to prevent injury. I will never attempt to work a muscle group without "warming up" first. By "warm-up" I of course mean actually exercising the target muscle group with light weight/medium-high range reps to prime the muscles/joints/ligaments before attempting to lift anything I consider heavy......Not walking, lol
question to future Q&A. How unhealthy are e-cigs? and how unhealthy are they compared to the various forms of smoking? Should I recommend e-cigs to my smoking friends? I seem to remember that Cigars/Pipe smoking has about the same risk of cancer, but usually it's in the mouth as opposed to the lungs. And I found a study on rats with vaporized nicotine inhalation that the only difference between the control group and the experimental group was body weight. This was of course a single study, and I had trouble getting past the abstract, if I did at all.
Well, as far as vitamins go, I've heard that if things change in food production certain things are taken out of food and become far more uncommon. An example is supposedly we used to get iodine out of bread, but changing the way its produced and prepared it doesn't have it anymore ( or most of it doesn't at least ) and it's more difficult to find it in foods, = more people with iodine deficiency.
What to do to live longer? Reduce your calorie intake! A low calorie intake (lower than "recommended", not extremely though) is thought to increase your life span. You'll be verrrrry thin, and might be a little upset because you won't eat a lot of sugary-fatty things, that we naturally crave. I recommend watching the documentary "Eat, Fast and Live Longer" from BBC Horizon
Could you please do an episode where you expand on the stretching/warm up thing? and could you add in information about stretching for flexibility and muscles shortening from certain exercises?
Will you do a video on the science regarding smoking vs. vaporizing? Everyday I see links to articles telling me that vaping is either harmless, or the worst thing I can do to my body. I WANT THE TRUTH!!!!
Stretching is GOOD for you. GOOD the study focused on people who did a stretching routine as their warm up and then did strength exercises. It concluded that if you are doing strength exercises then you'll be less likely to lift as much weight as if you did not stretch and instead did a warm up. YOU should STRETCH because you will not think that simply stretching is your warm up. This means pair stretching after a 30 seconds of jumping jacks or continuous lunges. I couldn't believe it when he said this so this is what I've come up with from 10 minutes of googling. If I've got this wrong please let me know, but before you do, please also do at least 10 minutes of googling. *not a doctor
2 cents here ... dye subject: a close personal friend has noticed a positive change in her 4-year-old's behavior after eliminating (as much as possible) artificial colors in his food. By the way - when you start to read labels, there are so many foods that contain artificial colors.
It isn’t the carbonation in soda that alters calcium. Phosphate (phosphoric acid) in cola binds with calcium. Not all sodas have phosphate. Clear soda, such as sprite usually don’t have phosphate.
6:57 I’d be curious to know if the problem could be that they’re stretching directly before or after their exercise and not separate from it. I struggle to see how increased mobility wouldn’t translate to decreased rates of injury
Perhaps those studies regarding stretching only looked at injuries. I understand that personal anecdotes don't count but me and pretty much everybody else I know get cramps (not injury) easier if we swim without stretching. There's got to be benefits to stretching beforehand. It makes sense that if you're an athlete and you're pushing yourself to the limits, stretching beforehand could potentially tire you out causing you to perform worse, but if you're just doing medium exercise, stretching is probably beneficial.
I work with a FNP and the way she explained the HDL vs. LDL is that HDL is "H"eavenly" and you want to keep that "H"igh, and LDL is "L"ucifer and you want to keep that "L"ow
The warm up thing I have to say I'm pretty skeptical that it isn't true. Just jumping immediately into strenuous exercise without warming up feels substantially different than if you do, I find my muscles just don't respond nearly as well.
They didn't talk about warming up, they talked about streching, wich is not the same at all. Doing jumping jack, running in place a bit and rotating your articulation is good, taking a pose and holding it for 30 seconds is useless.
Marie-Gabrielle Blais 7:14 watch it again. "Warming up doesn't actually help you perform any better." I'll contend that warming up helps performance because my joints aren't hurting or popping as much when I perform dynamic warm-ups, like bodyweight squats and pushups.
I will say that if you are deficient in a vitamin, then you should take that vitamin supplement with a meal and it will normalize your vitamin levels. Personally I'm low in Vitamin D, so I had to take a supplement because being deficient in D has adverse side effects. Other than that, the good doctor is correct.
That stretching one, that blew my mind. I've just finished training for a half marathon during which I was told that the reasons my leg muscles, shoulder muscles, and lower back muscles ached was because I didn't stretch them well enough. They said that it was to do with breaking down the lactic acid? What's the truth with this?
HDL and LDL are often misunderstood. They both start with an apoprotein which carries lipids as if the proteins were "sleds" of a sort. Straight after a meal, lipids absorbed in the gut get collected by the apoprotein, and that creates LDL (low density lipoprotein). The reason it is low density is because the apoprotein is low in concentration compared to lipids associated with them. The apoproteins bring lipids around to different parts of the body where they are consumed by cells that need it. To dividing cells, for example, or cells that need more cellular membrane (which is made from lipids). Repairs use lipids, and creation of cells from marrow, bursa, and thyroid. In fact, during illness, the body increases cells that produce antibodies, and making these cells as quickly as they are made, resources are depleted, including lipids. Okay, the LDL sled gets depleted as it makes its rounds. The lipids are low, and the apoprotein, by virtue of depletion, becomes more protein dense. That is HDL (high density lipoprotein). The only difference in LDL and HDL is how much lipid each carries. Like anything measured in the body -sodium, potassium, protein, blood cells, bile, etc.- there are expected amounts based on studies over the decades (century?) that doctors look at. And such is the case even for LDL and HDL. Both are needed, and there must be some of both to indicate a healthy balance; the system is doing what it needs to do: fill its apoprotein sleds, distribute the lipids to empty the sleds, then come back for more. If an apoprotein has a lot of lipids but can't get rid of them and comes back, it might get loaded down with more. Like a true sled, the apoprotein can spill its oversized load in the circulatory system in the form of plaques which get worse and worse till blood flow is restricted. That's why doctors look for a balance. And the reason HDL is "good cholesterol" and "LDL" is "bad" cholesterol is mere shorthand and has nothing to do with bad or good. They really are misnomers and should not be called bad and good. These days, it is more common and more necessary for people to form a peer relationship with doctors, to be partners in the patient's health. If patients learn terms like lymphoma, cholesterol, Marfan Syndrome, Cystic Fibrosis, Fibromyalgia, serotonin, melatonin, GABA, myeloma and others, we should respect patients enough to speak about the details of metabolism and illness and not resort to baby-fied, childish terms.
Re Vitamin Supplements :Winters in Canada normally are a bit grey and miserable. As a result we don't go out much and are often encouraged to take vitamin D to stave off SADS. Is there any justification in this action.
I have a question about exercising for 30 minutes a day. I probably exercise for a little big longer than that but it is over the course of the full day in five or so minute bursts when I decide I need to stop working at my computer and move around. Does the 30 minutes of elevated heart rate need to be continuous or is what I am doing fine?
CPR question: When giving chest compressions are you really supposed to give them so hard you break the persons ribcage? I have heard this from Dr's, nurses, EMTs and their teachers. I was curious if there are studies? Are rib cages easy to break and this is why it happens? How hard do you have to press to be effective and how hard is too hard? What is hard "enough"? Just wondering if this is a wives tale, or a widespread misconception or if there is even a study out there on this, and if so is it any good? Thanks and love your show!
Ya I've been certified a couple times and also completed my EMT, paid call fire and law enforcement module. In all of those I was also told the same thing. But I've had to re learn a lot of "common knowledge" and "makes sense" "facts" so I was just curious if this was one. If there's never been a study then, wow lol..
I worked as an EMT and as a patient care tech in an emergency room. I've given a lot of rib-breaking CPR. There's a reason doctors, nurses, and EMTs tell you that - it's true. The intent is not to break the ribs, but it is not uncommon when CPR is performed correctly. Yes, ribs are relatively easy to break compared to sturdier bones in the body. You have to press HARD for CPR. It is almost impossible for a human to perform CPR compressions 'too hard' - we just aren't that strong. You'd have to kneel on the person's chest or something. (Don't do that.)
Yes I understand what you're saying. Let's say I'm so much larger then the person I can literally break their spine through CPR, obviously too hard, and not compressing their chest at all is too soft. My point is, there has to be an optimal amount of pressure. And what if the difference between the optimal pressure and a non sternum cracking pressure was more beneficial then that extra pressure. I was wondering if there was a study and now that I've looked I can't find one. We just mapped a flying house fly's insides while flying, we ahould do something similar on a body to see how hard we need to go to be productive. If there isn't a study on how hard to do CPR then don't you think there aught to be?? I know I'm not against more science and education around something that could benefit myself one day. How many times has "common knowledge" been completely wrong, after all.
Found one study, Springer. "CPR: More Rib Fractures, But Better Survival Rates." ScienceDaily. ScienceDaily, 1 June 2007. . Say there is a sweet spot of 100-125lbs of pressure. Most untrained people don't use enough force and most trained people use too much. You don't have to crack the ribs to successfully perform CPR, but too much pressure is better then not enough. So the mentality of "harder=better" is a double edged sword. There are a lot of unnecessary injuries that could be avoided if the information and training were better. 1.5-2" of compression is what's needed. Breaking ribs and distending abdomens is a side effect of pressure in excess of 125lbs. Healthcare Triage *****
Hi, this was a great video, would it be okay if you made one on the efficacy of some different anti-depressants and/or whether they're the best method for treating mental disorders/if we're overmedicated? I read a lot of conflicting information about this, so your take on this would be really helpful.
hurray for chocolate milk! My soccer coach in hs use to tell us to drink it after practice for this reason haha. That was a fun Q&A. More of these please! Have you seen Fathead? I thought that was a fun documentary, I especially like the end where he eats bacon cooked in butter and eggs every day yet his weight and cholesterol all stayed healthy.
you messed up the HDL and LDL thing. Make an anotation to correct it
This guy is correct! Please upvote him.
Done. They now have an annotation at that time point 9:21
Happy Dancing Lance, Lay Down Larry
Probably better to make a note of it. "annotation" is marginal or footnote entries in a book that go into detail on a highlighted subject. "Notation" is a noun that means the act of taking notes. "Making a note" is writing down a concept once to be reviewed later. "Notate" is not a word. A person doesn't "Notate" something. They "note" it or "note it down."
Dr. C is one of those people that could say "I'm going to talk about random shit for an hour." and I'd sit down and listen. Perfect voice and charisma for being a speaker.
As much as I love the usual HT for making its points really solidly, many of us trust this channel for good info by now and this Q&A format covers a lot more ground in a more entertaining style.
More of these or a Healthcare Triage podcast every so often would be really cool.
I would love a Healthcare Triage podcast!
Alan Gebhardt Good idea!!! HCT Podcast! I'd have it in my daily subscription along with Planet Money, Freakonomics, Intelligence Swuared, and 99% Invisible.
a Podcast would be awesome!!
Wow, so many experts in the comments. All this guy is doing is relaying the outcomes of actual studies. Actual studies > your personal experience.
As a personal fitness trainer I always told my clients that they should skip the supplements until they reach a point where they are sleeping good every night, eating very healthy every day, and training intensely 5-6 days a week without compromise, and they feel they need to aid their body in coping with their intense training. Not as some kind of magic pill, so they can skip workouts, not put forth the effort, eat like unsupervised children, and still swell like Arnold.
"WHO'S THE DOCTOR NOW?!"
Not you John, not you.
Love this guy. The only thing he can do better is make more videos - the internet needs this kind of education!
Thanks!
the stretching thing is really surprising to me
***** Ah, but what exactly is being warmed up? Our internal body temperature doesn't change all that much, and when it does that's usually a bad thing (ie fever). Not to mention, what is the difference between stretching in advance and muscles being used during exercise? How does doing it in advance change anything?
When you think about it, stretching doesn't really make that much sense.
Taking things with a grain of salt here; just because there is no (statistical) data that shows both to be beneficial, it doesn't mean it always isn't.
I like to think of "warming up" and stretching as two separate things. Warming up can be anything like running or doing some exercises, which can exert the body just as much as whatever activity is performed afterwards. Stretching however, so long as you don't go overboard to stretch until you feel pain; WILL benefit you from straining muscles too hard later, especially before swimming. Don't want to get a leg cramps and drown in the ocean? Stretch.
What happens to clothes of certain fabrics after they're washed and hung to dry? Unless you lightly stretch them out while damp/wet, over time they shrink, and shrink, to the point you feel like it's a size smaller. The same can apply to muscles.
Long story short: everything in moderation.
GCyclone ....
Jake Hayes But I have noticed that if I don't stretch before martial arts practice, I can't kick as high, punch as fast, or run as fast. I don't believe it's a coincidence.
Vin Sad you could be more relaxed?
Straight forward, common sense, what's not to like about this guy?
On the stretching thing: it's important to note that he is talking about stretching before physical activity. In all honesty the best way to look at stretching is as another form of physical exertion. Obviously not an aerobic form.

Absolutely yes to the nutritional supplement answer- expensive pee. To the stretching- dynamic stretching before exercise prevents injury. Static stretching would not. Please be sure to specify the difference!
Such a huge fan of this channel! :)
This was probably my favorite episode yet. Do this again!
LDLs are bad - it helps me to think that the L is for Lethal
HDLs are good - H stands for Harmless
thats a great way to think about it.. gonna need this for my final thanks HAHA :D
A friend smokes; however, he also exercises regularly and he believes that by continuing to be active; exercising the organs prone to carcinogens (heart, lungs, etc.) that he might be offsetting some of the damage caused by smoking?
I have to admit; the guy works out hard; heavy cardio / Vo2-Max training /Road Cycling (20miles/day); and seems to be in good shape; even dives for abalone and can stay under water a lot longer than I can.
But, this just seems like something a smoker tells himself to continue smoking - a professional opinion would be helpful to educate him (or myself?). Thanks - love the shows!!
Direct feedback! I really liked this format. Aaron is much more engaging/lovable when he's interacting with a person right next to him. Also, I continually appreciate your "the sky isn't falling" approach: helps us focus on the real things, e.g. regular exercise.
I just realized how much more I enjoy watching Healthcare Triage videos without the constant jump cuts.
I only have one wish for this show. Whenever you mention a study/studies show, I kinda want them sourced, like links to those studies (hopefully somewhere on the screen) so I can look at them myself. I understand that this might logistically difficult. You are an expert I trust, I need that trust to be verified.
Great show.
Stop looking at Stan off camera!
But he's so handsome!
Would be great to see the study on stretching/warming up. Really hard to believe it's not working!
This is probably one of my favorite HealthCare Triage videos yet. Dont' get me wrong, I love all these videos, but this one had a lot of good information packed into a single segment. Keep it going, we're listening.
I absolutely love this channel! I'm always the one telling people to look up the studies. I hate hearin, "They say you should do X, or Y." My first question is, "who says that?" I always push people to look at the studies, the evidence, see what they say. And I love that this channel dives fully into that. If I could cuddle up with this channel, I would.
This was actually a really informative and diverse video; I hope you get to do more of these Q&A videos. :)
I LOVED THIS! I loved how conversational it was, and how informed Aaron is. You guys (and for once, I mostly mean NOT John Green) are awesome.
wow you just cleared up so many misconceptions for me. You should do more of these
Very informative! I watched it straight through to the end. I'm so glad this channel exists because it's nearly impossible to get unbiased and accurate information from someone who truly knows what they're talking about. Keep doing what you do! :) it's great.
My English teacher brought up the study about Oreos and cocaine in class and was totally invested in the idea that Oreos were as addictive than cocaine.
ʕ•͡.•ʔ *facepalm*
As a nutrition student, I found the mix up between HDL and LDL disturbing, especially since the correction was in the description at the bottom. HDL is the so called "good" cholesterol and LDL the "bad" cholesterol. Although you are right, food consumption does not alter either (but exercise does!).
Also, many people at many geographical locations would benefit from a vitamin D supplement in the winter.
This was a real fun watch. Thank you, gentlemen. Now I want to meet Aaron real-live even more. He has a style of thinking that I really like.
How did the the highschool/college students get the cocaine? I mean there's the obvious drug dealer path, but how would they get that published? And who knew the guy who has a drug dealer? And if they got it legally somehow, who was monitoring everything? SO MANY QUESTIONS!!!
well in the UK there is medical use of heroine, so maybe there is a way to legally use cocaine?
You can get access to a lot of things for study purposes - you just have to apply for it.
If you're researching addictive behavior, you can legally get addictive agents. As for who monitors it (besides their research supervisor, of course), I would assume the FDA and possibly the DEA.
Mallinckrodt Pharmaceuticals can legally make cocaine in the United States, but I'm not sure if they're alone. I mean Pharmaceutical companies usually have access to many illicit drugs. They likely buy from Peru, where it is semi-legal to farm coca plants (although I'm sure other countries have fields for medical/research purposes). So my guess is that Universities gain access through Pharmaceutical companies for research purposes.
***** So that's why there are so many studies on addictive drugs. A hit for the rats, a hit for the techs...
I'm so happy, you just removed the guilt I felt for never, ever stretching before strength training. Hurray!
My confidence in everything you said went out the window when you got HDL and LDL mixed up.... Guess I'm going to have to go back to webMD to quench my need for medical advice/information.
Yes because off the cuff guesses are just as reliable as when they spend a week writing and researching a episode. It's not like one doctor can have everything in medical science in his brain and on speed dial.
I was clearly joking.
Isn't he a pediatrician? I can't imagine cholesterol comes up very often at work.
I like Aaron's casual style here better than the accusative style of most other videos. _Having said that_, I do find these video's very interesting and informing. Keep up the good work!
This is a great video. Keep up the good work, Triage has quickly became one of my all time favorite video libraries.
I glad you made the distinction between multivitamins and supplements. Some people act like it's crazy to take multivitamins as well, whereas it seems kind of obvious that if your body is a little low on something it can get it from the multivitamin whereas taking huge amounts of individual vitamins is just going to cause you to pee them out.
My understanding of the stretching thing is this: When you stretch, it does more to separate the muscle fibers. Kinda like "ripping" though muscles don't actually "rip".
But in either case, when you go to exercise, if 10% of your muscle is "ripped", then the force is focused on the remaining 90% and thus you perform worse, gain less, and are at more of a risk for injury.
The main benefit I can think of is avoiding tendon damage due to lack of flexibility. But in that case, you can do something like yoga at any time to get the same benefit.
This is great news about stretching. I teach a walking class and the thing that really bogs people down is the amount of time we spend stretching.
In regards to the satisfaction question, I find that very true. My sister was going through a stressful time in her life but was not suffering from any mental illness like anxiety, but her doctor still gave her anxiety medication so she left there happy.
From a professional sports career (climbing) and a heavy training (gymnastics) what I can tell in favor of stretching after the effort is that it increses flexibility which is important since heavy exercise WITHOUT stretching decreases it pretty fast.
Yet, I have but 10+ years of experience witnessing that so I don't know to what extent this is exact or only applying to me.
I find flexibility by itself is really useful and nice to have, even if for no other reason than to be able to tie your own shoelaces.
I also agree. I really like being able to touch my toes, and kick above my head.
Oh! You were doing so good until 6:46 when you fell into the trap of associating body size with diet. It is a commonly held misconception that you can tell a person's diet by looking at them. Turns out, looking at somebody doesn't provide that information.
But I actually know John. It's not just based on a glance...
Healthcare Triage I realize that, you did say "looking at you and knowing you", I was only taking issue with the first clause, not the second.
vlogerhood It's just conversational language, I don't hold it against anyone. The point he was making was clear enough to me.
The things we say, even conversationally, inform and impact our thinking and beliefs. In this context: an expert speaking in an informational video, it is especially important that casual phrasing not support bad thinking and unsupported but common beliefs.
I think Dr. Carroll agrees that you can't tell a person's diet by looking at them, so that is why I suggested he not say it, even conversationally. Because that belief is actually held by many people and can be quite hurtful when expressed.
vlogerhood Ah, point well taken.
I learned from my doctor that HDL is good and you want it to be high (they both start with "H"). LDL is bad and you want it to be low (both start with "L").
Some pretty mindblowing info in here! Thanks. I shared it on facebook. My fitness buff brother will probably dispute some of the facts. Let me ask so that I know when he brings it up: when you say nutritional supplements don't make a difference, does that mean drinking protein shakes or eating protein bars doesn't help build muscle? Is that what was implied in the conversation about John's guns? Thanks in advance!
Oh this is a great segment! I hope you guys will do these every now and then!
Aaron I don't understand your hoodie. Why are there so many zippers? Why are they all vertical? Why is one silver and the others black? Why does healthcare make more sense then that hoodie?
Correction, at about 9:30. LDL is the bad cholesterol. HDL is good cholesterol. Low density proteins are big and chunky and cause blockages, High Density proteins are all smushed up and kinda just do their own thing regardless of your clotting factors. VLDL is the worst though, Very Low Density Lipoprotein.
Do an episode on circumcision!!! And do one stretching.
DEFINITELY.
this has been the most entertaining interview, Q&A (or what ever you call this) on youtube.
i've learned a lot and laughed a lot. you guys are awesome!
Also, John, you looked so sad when you said Henry already hates you!
LDLs are the cholesterols your GP gets upset over. It's generally accepted that they are more harmful than HDLs.
11:00 disagree - they WERE actually talking about eight hours of continuous sedentary behavior (i.e. stuck in a cubicle) increasing risk for CVD, not exercise. most people don't actually do that unless they never leave their desk even for lunch, but IIRC, that was the point they were making.
10:59 - I remember that study and that's not what they said. As John mentions, they specifically noted that men (it was exclusively men in the study) that exercised regularly were just as likely to have cardiovascular disease as those who never exercised when both were sitting more than 4 hours a day. Exercise did not reduce their chance of heart attack.
Stretching is important, but not nearly so much before performance. More so after a hard workout so that you are not as stiff the next day. Also, stretching makes you more flexible over time. (Imagine that!) And that does eventually affect performance, obviously. It's just that a single stretch routine right before a particular performance will not have a noticeable effect on that performance.
Damn, totally missed out on the call for questions. Can't wait for the next one!
Any chance you could elaborate on the bodybuilding stuff? Because other people seem pretty sure that protein + working out = muscles.
I'd really like to hear your thoughts on it.
I *think* what he was talking about there were nutritional supplements, mostly. Like, getting more of various vitamins and stuff doesn't help with building muscle. I could be wrong though.
UnqualifiedAdvice
Think so too but on the other hand he said protein shakes... And in short even bodybuilders don't need protein supps and especialy if they are not on juice. Why they exist? Well they help. A general rule of thumb is 2g of protein for 1kg of lean body mass per day. And that's the top end, some say it's less and some say it's more. you probably can ignore the ones who say it's more and test out if less is enough for you. You need protein for muscle development and IF you don't eat enough, than supplements might help. That's the same with supps in every part of the life. They only make sense if you are deficient in something, you should allways try to get your macro- and micro nutrions in through "real" food.
I think that the kind of protein (like creatin) you take doesn't really matter because your gastric acid contains pepsin that breaks apart any protein into amino acids. I imagine it could be beneficial to take proteins with amino acids that your body can't synthesize but if that isn't really significant i'd say eating any source of protein is about as good as the other and you don't really need creatin powder.
Teun van den Brand
creatin works. That's one of millions supps that is actually tested in 100. of studies but it'll give you maybe 5% to 10% more strengh, not more. It's not any magic (also not protein).
Coming from being an athlete in college working out 30+ hours per week working out = muscles; protein = muscles get repaired at quickly as possible. Not having enough protein slows muscle repair.
That being said, a balanced diet will provide all of the protein you need. Just don't eat a crappy diet.
This was an awesome video! I love the health myth busting you're doing and I wish everyone I know would watch this
Hey Aaron, could you elaborate more on the questions of vitamins and supplements impacting health? I am aware of a meta analysis in BMJ that showed considerable benefits to having sufficient levels of Vitamin D, and most patients (especially us high latitude folk) have insufficient levels so supplementation would be beneficial. What about Vitamin C prior to an operation or during cold/flu season? What about essential oils like Omega 3? I think there are a lot of misconceptions, but potentially some benefits as well to this topic.
Love your talks, always good for sparking conversation.
Thanks.
Aaron seems so likable in this video. Normally he just seems exasperated and sarcastic.
Really great video! I hope you'll continue making them! :)
I'd love to hear more about the vitamin supplements. (yeah, I know, a simple "NO!" is great, but, atleast here in germany, there are so much contradicting statements)
I can not go to nearly any place in TH-cam with out goddamn John green showing up
You talked in previous episodes about healthcare in the us and canada. Which country do you think has the best healthcare system? Also how would New Zealand rate?
On another note an episode on stretching would be nice
it was fun to see the discourse b/w John and Aaron... made me smile :D
Oh god, the milk bit at the end was hilarious.
Walking after exercise also helps prevent blood pooling.
Strictly anecdotally, I find that warming up before exercise, like bodyweight squats, etc helps to loosen up the joints, decreasing pain during intense exercise, helping flexibility, and preventing sudden popping and moving of joints. Additionally, the joints that have problems are ones that I hurt as a teen, having torn ligaments or muscles or sprained.
Yes, but there is a difference between a warm up and stretching.
alecbg919 He shot down warming up in the same statement.
not exactly, he said walking would be more beneficial than stretching because although there is not alot of evidence to support it, it at least makes sense because you start to move the lactic acid in your body. Again, it all depends on your definition of "warm up" personally, I would not categorize walking as such. I think he is speaking more of a warm up routine than a stroll around the block. I mean we are constantly walking anyways so why would it be considered a warm up exercise? I dunno, just doesn't make sense to me at least.
Jim Mulvaney Mentioning walking and "moving" lactic acid was mentioned as part of a cool down, not warm up, as in after strenuous exercise is completed.
After repeat viewing, it could be construed that the term "warm-up" was used as a colloquial synonym for "stretch" merely to break the flow and prevent redundancy of terminology.
Well, as a fitness freak, I will say that "warm-up" exercises are a necessity to prevent injury. I will never attempt to work a muscle group without "warming up" first.
By "warm-up" I of course mean actually exercising the target muscle group with light weight/medium-high range reps to prime the muscles/joints/ligaments before attempting to lift anything I consider heavy......Not walking, lol
question to future Q&A. How unhealthy are e-cigs? and how unhealthy are they compared to the various forms of smoking? Should I recommend e-cigs to my smoking friends?
I seem to remember that Cigars/Pipe smoking has about the same risk of cancer, but usually it's in the mouth as opposed to the lungs. And I found a study on rats with vaporized nicotine inhalation that the only difference between the control group and the experimental group was body weight. This was of course a single study, and I had trouble getting past the abstract, if I did at all.
Please do an episode about the Myths surrounding fluoride.
I just told my husband this week that chocolate milk worked as well as those expencive protein drinks, but he bought them anyway!
As always, another great video from Healthcare Triage.
LDL = "bad" cholesterol; HDL = "good" cholesterol
Could you talk about the balance between Omega3 and Omega6 fattyacids, and how the ratio has changed drasticly since the 1960s?
Please do an episode on the science of medicinal cannabis, as well as your expert opinion on it. Please!
Well, as far as vitamins go, I've heard that if things change in food production certain things are taken out of food and become far more uncommon. An example is supposedly we used to get iodine out of bread, but changing the way its produced and prepared it doesn't have it anymore ( or most of it doesn't at least ) and it's more difficult to find it in foods, = more people with iodine deficiency.
What to do to live longer? Reduce your calorie intake! A low calorie intake (lower than "recommended", not extremely though) is thought to increase your life span. You'll be verrrrry thin, and might be a little upset because you won't eat a lot of sugary-fatty things, that we naturally crave.
I recommend watching the documentary "Eat, Fast and Live Longer" from BBC Horizon
Could you please do an episode where you expand on the stretching/warm up thing? and could you add in information about stretching for flexibility and muscles shortening from certain exercises?
Also stretching for pulled muscles?
Will you do a video on the science regarding smoking vs. vaporizing? Everyday I see links to articles telling me that vaping is either harmless, or the worst thing I can do to my body. I WANT THE TRUTH!!!!
Stretching is GOOD for you. GOOD the study focused on people who did a stretching routine as their warm up and then did strength exercises. It concluded that if you are doing strength exercises then you'll be less likely to lift as much weight as if you did not stretch and instead did a warm up.
YOU should STRETCH because you will not think that simply stretching is your warm up. This means pair stretching after a 30 seconds of jumping jacks or continuous lunges.
I couldn't believe it when he said this so this is what I've come up with from 10 minutes of googling. If I've got this wrong please let me know, but before you do, please also do at least 10 minutes of googling.
*not a doctor
You guys rock! Keep the light of evidence based medicine shining! :D
This video looked like it was a lot of fun to make. I think that is why I enjoyed it so much :)
2 cents here ... dye subject: a close personal friend has noticed a positive change in her 4-year-old's behavior after eliminating (as much as possible) artificial colors in his food. By the way - when you start to read labels, there are so many foods that contain artificial colors.
It isn’t the carbonation in soda that alters calcium. Phosphate (phosphoric acid) in cola binds with calcium. Not all sodas have phosphate. Clear soda, such as sprite usually don’t have phosphate.
6:57 I’d be curious to know if the problem could be that they’re stretching directly before or after their exercise and not separate from it. I struggle to see how increased mobility wouldn’t translate to decreased rates of injury
Perhaps those studies regarding stretching only looked at injuries. I understand that personal anecdotes don't count but me and pretty much everybody else I know get cramps (not injury) easier if we swim without stretching. There's got to be benefits to stretching beforehand. It makes sense that if you're an athlete and you're pushing yourself to the limits, stretching beforehand could potentially tire you out causing you to perform worse, but if you're just doing medium exercise, stretching is probably beneficial.
30 sec. Workouts is all I need? Got it
I work with a FNP and the way she explained the HDL vs. LDL is that HDL is "H"eavenly" and you want to keep that "H"igh, and LDL is "L"ucifer and you want to keep that "L"ow
I'm kind of embarrassed that you answered a joke question from me haha. Very good video guys!
The warm up thing I have to say I'm pretty skeptical that it isn't true. Just jumping immediately into strenuous exercise without warming up feels substantially different than if you do, I find my muscles just don't respond nearly as well.
They didn't talk about warming up, they talked about streching, wich is not the same at all. Doing jumping jack, running in place a bit and rotating your articulation is good, taking a pose and holding it for 30 seconds is useless.
Marie-Gabrielle Blais 7:14 watch it again. "Warming up doesn't actually help you perform any better." I'll contend that warming up helps performance because my joints aren't hurting or popping as much when I perform dynamic warm-ups, like bodyweight squats and pushups.
I will say that if you are deficient in a vitamin, then you should take that vitamin supplement with a meal and it will normalize your vitamin levels. Personally I'm low in Vitamin D, so I had to take a supplement because being deficient in D has adverse side effects. Other than that, the good doctor is correct.
That stretching one, that blew my mind. I've just finished training for a half marathon during which I was told that the reasons my leg muscles, shoulder muscles, and lower back muscles ached was because I didn't stretch them well enough.
They said that it was to do with breaking down the lactic acid? What's the truth with this?
HDL and LDL are often misunderstood. They both start with an apoprotein which carries lipids as if the proteins were "sleds" of a sort. Straight after a meal, lipids absorbed in the gut get collected by the apoprotein, and that creates LDL (low density lipoprotein). The reason it is low density is because the apoprotein is low in concentration compared to lipids associated with them.
The apoproteins bring lipids around to different parts of the body where they are consumed by cells that need it. To dividing cells, for example, or cells that need more cellular membrane (which is made from lipids). Repairs use lipids, and creation of cells from marrow, bursa, and thyroid. In fact, during illness, the body increases cells that produce antibodies, and making these cells as quickly as they are made, resources are depleted, including lipids.
Okay, the LDL sled gets depleted as it makes its rounds. The lipids are low, and the apoprotein, by virtue of depletion, becomes more protein dense. That is HDL (high density lipoprotein). The only difference in LDL and HDL is how much lipid each carries.
Like anything measured in the body -sodium, potassium, protein, blood cells, bile, etc.- there are expected amounts based on studies over the decades (century?) that doctors look at. And such is the case even for LDL and HDL. Both are needed, and there must be some of both to indicate a healthy balance; the system is doing what it needs to do: fill its apoprotein sleds, distribute the lipids to empty the sleds, then come back for more.
If an apoprotein has a lot of lipids but can't get rid of them and comes back, it might get loaded down with more. Like a true sled, the apoprotein can spill its oversized load in the circulatory system in the form of plaques which get worse and worse till blood flow is restricted.
That's why doctors look for a balance.
And the reason HDL is "good cholesterol" and "LDL" is "bad" cholesterol is mere shorthand and has nothing to do with bad or good. They really are misnomers and should not be called bad and good.
These days, it is more common and more necessary for people to form a peer relationship with doctors, to be partners in the patient's health. If patients learn terms like lymphoma, cholesterol, Marfan Syndrome, Cystic Fibrosis, Fibromyalgia, serotonin, melatonin, GABA, myeloma and others, we should respect patients enough to speak about the details of metabolism and illness and not resort to baby-fied, childish terms.
Re Vitamin Supplements :Winters in Canada normally are a bit grey and miserable. As a result we don't go out much and are often encouraged to take vitamin D to stave off SADS. Is there any justification in this action.
I have a question about exercising for 30 minutes a day. I probably exercise for a little big longer than that but it is over the course of the full day in five or so minute bursts when I decide I need to stop working at my computer and move around. Does the 30 minutes of elevated heart rate need to be continuous or is what I am doing fine?
Am sorry that Aaron doesn't mention increasing exercise as a primary way to increase the good (HDL) cholesterol which helps lower the bad (LDL).
Stretching to warm up/cool down may be silly, but stretching so you have more range and flexibility certainly isn't silly at all.
I loved this video! You should do more Q&As. Keep it up!
John's diet "decent"? but all he eats is pizza! Is pizza healthy? :O nah, seriously, great Q&A, guys, keep em coming!
30 seconds! He said it, I'm going with it!
I love this style of video! do more of them please!
Definitely do more. Free healthcare advice is nice.
CPR question: When giving chest compressions are you really supposed to give them so hard you break the persons ribcage? I have heard this from Dr's, nurses, EMTs and their teachers. I was curious if there are studies? Are rib cages easy to break and this is why it happens? How hard do you have to press to be effective and how hard is too hard? What is hard "enough"? Just wondering if this is a wives tale, or a widespread misconception or if there is even a study out there on this, and if so is it any good? Thanks and love your show!
Ya I've been certified a couple times and also completed my EMT, paid call fire and law enforcement module. In all of those I was also told the same thing. But I've had to re learn a lot of "common knowledge" and "makes sense" "facts" so I was just curious if this was one.
If there's never been a study then, wow lol..
I worked as an EMT and as a patient care tech in an emergency room. I've given a lot of rib-breaking CPR. There's a reason doctors, nurses, and EMTs tell you that - it's true.
The intent is not to break the ribs, but it is not uncommon when CPR is performed correctly. Yes, ribs are relatively easy to break compared to sturdier bones in the body. You have to press HARD for CPR. It is almost impossible for a human to perform CPR compressions 'too hard' - we just aren't that strong. You'd have to kneel on the person's chest or something. (Don't do that.)
Yes I understand what you're saying. Let's say I'm so much larger then the person I can literally break their spine through CPR, obviously too hard, and not compressing their chest at all is too soft. My point is, there has to be an optimal amount of pressure. And what if the difference between the optimal pressure and a non sternum cracking pressure was more beneficial then that extra pressure.
I was wondering if there was a study and now that I've looked I can't find one. We just mapped a flying house fly's insides while flying, we ahould do something similar on a body to see how hard we need to go to be productive. If there isn't a study on how hard to do CPR then don't you think there aught to be?? I know I'm not against more science and education around something that could benefit myself one day. How many times has "common knowledge" been completely wrong, after all.
Found one study, Springer. "CPR: More Rib Fractures, But Better Survival Rates." ScienceDaily. ScienceDaily, 1 June 2007. . Say there is a sweet spot of 100-125lbs of pressure. Most untrained people don't use enough force and most trained people use too much. You don't have to crack the ribs to successfully perform CPR, but too much pressure is better then not enough.
So the mentality of "harder=better" is a double edged sword. There are a lot of unnecessary injuries that could be avoided if the information and training were better. 1.5-2" of compression is what's needed. Breaking ribs and distending abdomens is a side effect of pressure in excess of 125lbs.
Healthcare Triage *****
Hi, this was a great video, would it be okay if you made one on the efficacy of some different anti-depressants and/or whether they're the best method for treating mental disorders/if we're overmedicated? I read a lot of conflicting information about this, so your take on this would be really helpful.
hurray for chocolate milk! My soccer coach in hs use to tell us to drink it after practice for this reason haha. That was a fun Q&A. More of these please! Have you seen Fathead? I thought that was a fun documentary, I especially like the end where he eats bacon cooked in butter and eggs every day yet his weight and cholesterol all stayed healthy.
