This documentary changed my life. I have lost 65lbs, gotten stronger and reversed early onset of metabolic syndrome. Grateful for this man and wisdom he has shared. Unfortunately so many ignorant beliefs on food and sugar addiction. As an addiction specialist I am ecstatic with the development of brain science and physiology of the endocrine system.
If a product says its low in fat then you can guarantee it will be high in sugar. Food labels can be very deceiving. And healthy foods are always very expensive compared to fatty and sugary food, which are so cheap and seem to be everywhere you go.
Lynda Murray okay to circumvent that, don’t buy any processed prepackaged foods or any junk food and eat your sugar and fat from natural plant sources.
Fast food used to be a treat. I remember my folks (who both worked) ) late 60s early 70s, would buy it for us kids on a Friday night when we would all go out to the drive in movies. Kentucky fried chicken once or twice a year. Pizza 3 or 4 times a year. Chinese rarely. Now people eat these (food treats) as dinner, and for most of their meals? Also, my folks wouldn't dream of serving soda with any meal, except for summer BBQs and picnics, a weekend treat. Jeez, soda used to be expensive, and you never got free refills. I raised my kids the same way. I'm tired of being visually assaulted every time I leave the house. Most have no shame and flaunt it with tattoos and skimpy clothing. Its just unbelievable how quickly obesity has become the norm. Make time to cook at home once in a while, and when your kid is hungry between meals, give them an apple or an orange to suffice. Its OK and used to be normal to feel hunger between meas. Its just awful the things I see kids eating, that their parents choose to give them, as they walk around the grocery store and streets. I'm really beginning to think, now that there are so many obese people. How in the world are they going to raise normal weight and able children, when they themselves refuse to see the light. Just sickening. Stop buying all that processed sugary garbage, and reeducate yourself on eating life giving foods. Its really not that difficult. Sorry for the rant. Just spent!
***** There is no way to lose fat fast. You are destined for failure. Stop spreading your scam. Eat sensibly and watch your daily calories and move. Pretty simple.
+larkatmic who's selling anything? Dr. Lustig is giving you information for free! This isn't some quick fix buy my book video.. There's no scam being spread.. get a clue daily calorie counting doesn't work.. Did you not watch the video???
in my college evrybody eats fast food and i pack my own food in tupperware and eat that instead, they always make fun of me for it and call me a health freak. and im just like really... just because i dont wanna eat pizza and burgers evry single day im a health freak, but thats society today.
I lost 80 pounds counting my calories (1000 less a day = 2 pounds a week), eating GOOD QUALITY food, and exercising. Counting calories does work. You are just look for excuses.
Joe Edwards, Keep it up! I hope you aren't hungry. I am on almost 2000 calories a day, not that I'm really counting, just eating twice a day until I'm full, exercise 2 - 3 times a week on a treadmill and rowing machine for about 70 minutes each time, getting my heart rate to approximately 2.5 resting (resting = 43). I have been doing this for less than 6 months so about 2 lbs a week. Why are my daily calories double yours and I'm losing the same amount of weight each week with only a small amount of exercise? Probably what I am eating and how the body metabolizes it, wouldn't you say? I'm never hungry except before eating of course. No snacks.
good fat is limit 20-30 grams per day and protein under 50 gram per day. if you need workout can more protein and also you need good carbs limit because you need energy. NO Bread and pasta is bad carb.
i am doing the high carb ovovegetarian diet. i am satisfied with what I eat and slim. but I don't use table sugar. so yes for complex carbs and fiber and a big no no for sugars. but fruit is ok (as there's plenty of fiber).
I'm from Norway, when I visited the USA I went into the supermarket and picked out a cereal that looked like it had little suger in it( it was a bit hard to compare since it's not in %', but it was among the better once). I then picked out some low fat milk to go with it. It was so sweet I couldn't stomach it. I forced down a bowl, the rest went in the trash. Back at the supermarket, new reading og labels of a dozen of cereals, came back with what seemed the lowest in sugar, made a bowl with milk. Again I ate one bowl, threw away the rest, it was too sweet to sweet to eat. After 2 weeks I went back to Norway, but 8 months later I came back to America for a 2,5 month stay. This time I brought with me the cereal I ate in Norway. Bought the low fat milk again, (didn't knew any better back then), and again the cereal tasted sweet. What was going on? This time I could eat it, but it was still way sweeter than back in Norway. It's not like someone poured suger in the box while I flew over the Atlantic. The only thing that was changed was the milk, so I checked it. In Norway, low fat milk is low fat milk, In the USA low fat milk is low fat milk with 37% more sugar. I poured out the milk and gave up totally on cereals at that point. My diet wasn't great when I was over there. I ate some hamburgers and fries, some pizza and tacos and sandwiches, but since the products was different than the Norwegian once, I didn't knew how to cook with them, so I ended up eating a LOT of cheddar cheese, almonds and apples. Tended to be my evening meal almost every day and sometime during the day too. I also snacked on seeds now and then. Now I was NOT dieting, and ate whenever I was hungry, I still lost 5 pounds during that time. Without thinking about it I had increased my fat intake and, despite some bad meals, decreased my carb intake. And it caused me to loose weight. So I say Americans probably have a harder time avoiding the sugar products as they are way more abundance than in some other countries, but it's still possible. I did it without even trying. Of course cheese and almonds is not a good long term solution, but the LCHF defiantly helps regulate your appitate and will probably cause you to loose weight.
I'm a bit of a homebody and thought that this will do well for me, since exercising requires a lot of time, effort, and equipment. Weight loss green store tea worked very well for my needs and was an excellent appetite suppressant.
adding to that is our odd hours at jobs such as driving trucks, working lengthy periods where excess to healthy food isn't available because it's just grab and go. some ppl skip breakfast altogether while others can't seem to put down the fork. ppl are emotionally tied to food, they are socially tied to food. also, mothers who work more than one job or single households where food becomes less of a priority because the emphasis is what doesn't kill me right now is alright to keep doing.
for those of you that are over weight watching this video, all it takes is one click, the right mindset, the ability to research what you need and the desire to get it done! if you find what you need you'll be a new you in less than a year! or even far less than that!!!
Lustig says "it hasn't worked" referring to the idea that a calorie from carrots is the same as a calorie from cake. While that may be true, he's also ignoring the fact that Americans haven't even been trying to get their calories from sources like carrots; people in this country do not eat anywhere near the recommended amount of fruits and vegetables.
Not so. Fruit is a simple sugar, unlike refined sugar and cane sugar. The body does not usually have a problem with fruit raising insulin levels. Did you know that sugar is also in vegetables as well? Basically any carn is a sugar. Fruit also helps people get sweet tasting food without as many calories, and it has many vitamins we need.
Just bought hamburger rolls at Costco. By the label you would think you are buying health food. The label contains the USDA food plate, and some bogus statement about how grains are essential for your well being. And no trans-fats of course (did hamburger buns ever have trans-fat?). It is a very sad state of affairs. And who is head of the USDA? The former governor of Iowa. And whose interests does he represent? That's right, the wheat and corn (HFSC) producers. What a joke.
I almost never eat fast food and Im still 30 lbs over weight at least. I do jogging, tennis, bike riding, swimming, weight lifting. I count calories.. I still cant lose this excess fat. Most of it is the flabby kind of fat, not the dangerous visceral kind. But its still very hard. I know some thin people and they dont diet or exercise. Its really frustrating. People dont understand how hard it is to lose weight.
@@dylanisaac1017 Pretty sure drinking pure H2O (actual distilled water) is harmful for you. You'd have to look it up to verify. Nothing wrong with a charcoal filter though :)
So true... the only person to blame is yourself.... learn proper nutrition and portion control and practice it.... you will get use to it and you will drop the weight. I was recently in the hospital for and infection due to complications with uncontrolled diabetes and basically forced into a low cal portion controlled diet, by the time my hospital stay was over I was already used to it and have kept eating that way. I have dropped 15lbs in 2 weeks and plan to continue eating like this for good.
This excellent presentation omits a sacred cow--the contribution of rapid growth and increased height to the obesity epidemic. Birth weight is tied to the mother's height and weight before pregnancy. These factors promote higher birth weight and birth weight is correlated with overweight and obesity. Freedman also found that children that are tall at about 8 years of age are 5 times more likely to become obese adults compared to 8 year olds that are shorter than average. Thomas Samaras
i am doing the high carb ovovegetarian diet. i am satisfied with what I eat and slim. but I don't use table sugar. so yes for complex carbs and fiber and a big no no for sugars. but fruit is ok (as there's plenty of fiber).
Liz, I have worked with several clients who do follow the low fat, high fiber diet. For example, eating Fiber One bars and many other "diet products. It doesn't work for long term sustainable weight loss.
You are right. There are so many factors involved in metabolism and weight loss that we are still discovering new things regarding this. The body is a very complex mechanism, more so than anyone has previously realized. And then there's the genetic component...people who were able to hold onto fat lived through famines and thus passed these "fat genes" along.
maybe you have a food sensitivity that is causing inflammation... losing weight requires more than exercise and not eating fast food. It is about the TYPE of food you eat. Its about eating real food...not foods with preservatives and junk in them. I totally understand what you are saying though. It isn't easy. It requires research and lifestyle changes. Watch some videos or read some blogs by Dr. Mark Hyman. He has some really great tips that WILL help.
Yes, there are other factors, but exercise and a healthy diet help regulate hormones, insulin levels, serotonin levels, etc. That said, it might not make you a supermodel; however, it will help maintain weight at a reasonable level, unless you have a severe condition, such as brain tumors, etc.
As someone on the Paleo diet now for nearly two decades, I also have kept my weight down ( do have good, healthy muscle and bone mass), my blood serum markers are all inl the right places, and my skin is clear and soft. In fact, despite being in my mid-40s, people routinely mistake me for a 30 year old. So, does what you do work because like me you gave up grains and most sugars? Think about that.
No. Sugar causes a "feel good" response in the reward center of your brain, so you crave more. This is equal to the response delivered by cocaine, heroin, caffeine, nicotine and several deadly-addictive compounds. And the more sugar you eat, the more that is required to get that pleasurable feeling, so your intake multiplies exponentially.
That's why I look mainly at calories, sugars & carbs. Fats are viewed too, but usually when calories are high so are the fats. If you decrease calories, you're also decreasing fats. Fats & calories are twins, If one is high, usually the other is just as high or higher. :) I also noticed that calories aren't always the case of gaining weight, carbs are. I decrease my carbs intake to 70-90g & I lost weight fast. If I were on the stricter end of Atkins (0-50g Carbs.) I would be a size 0 in a month.
Yes but it can be almost always tracked back to what I have mentioned. And yes, Enviromental toxins mainly aditives in junk food. When it comes to insulin resitance that is almost always caused by having more sacharide in your diet than you can handle. I have lost huge amount of weight simply by cuting sacharide (adjusting to the level of the activity), ditching plant oils and eating much more satfat. In two years I have lost 40kg and got tremendous muscle gain.
and expensive. I'm not trying to be negative but there was a time I couldn't afford fruits and veggies and gained a lot of weight. In some places you can buy 3 tomatoes for the same price as 20+ ramen packets. When you need to stretch your money, which are you going to choose?
sorry, the graph for both increases together - i can always mislay the single important fact. NB top tip if trying to cut the fat but needing the taste hit, something strong tasting like horseradish sauce, not good for you (sugar & fat) but if you put it only on top of your food, not in it, you do use less sugar usually
And last of all. If you are having problems like bad headache after eating sugary food you would do well to have yourself checked up by the doctor. They can actually measure how well your body responds to glucose and insuline and pinpoint the problem.
Saccharides is the correct term used for what anglo-american people are used to call carbohydrates. That is archaic term derived from poor udnerstanding of their chemical structure. The sachs aren't problem on themselves nor is it neccesary to cut them. You nearly have to adjust them depending on your level of physical activity. You can't sit in school/job all day eating bagels and stuff but sure as hell can't go through heavy exercise without having some stockpiled ready to be used.
Could someone explain to me, how does this presented here information that high glycemic index carbohydrates are a major cause of the obesity epidemic in the US reconcile against diagrams of chartsbin . com, which show that fat consumption in the US is much bigger than in most of other countries, while carbohydrates intake percentage is actually lower in the US? I don't understand it.
I can remember when the mantra was: simply take in less calories than you burn (some still are sticking with this). It should have become apparent a long time ago that it's not that simple. The body processes different foods in a different manner. Plus the fact that people fall into different metabolic groups. What works for one does not necessarily work for another. For instance, I need a high activity level coupled with low fat diet, while others can get by with moderate exercise.
This is good to hear. I'm sure there are others like yourself who benefited, but this does not validate the diet, nor does it refute the arguments made by medical community re. its dangers. There are always exceptions to each case. There are people who get well from placebo but it does not mean we start using placebo as a treatment medicine.
Question: If Sugar intake has decreased 40% and consumption of animal fats has also been reduced, where have the calories that are making people obese coming from? I don't think anyone is claiming a magic bullet. But if we can turn the clock back 30 years, that would be a real achievement. Eating like we did 30 years ago would go a long way to bringing that about.
what constitutes saccharides? Is it just chocolate, table sugar, white/bleached/flour? It's really hard to cut them out since these foods are literally everywhere and when I eat them I get a tremendous headache....how did you do it? just went cold turkey?
This is a great video. Though it is a little daunting to those who aren't familiar with these facts or a fan of nutritious eating.. However, as a recent vegetarian and having given up fast foods, pastries, and over sweetened coffees and desserts my life has only changed for the better. I've lost 20 lbs with little effort, have clear skin and don't crave obnoxious amounts of foods, fats, or salts/sweets.. Everyone should re-evaluate their diet. UCSD Grad, Muir college class of 2011
I know fast food, and bigger portions have a lot to do with the increase in obesity, but facts are people, these days, are so much lazier than they were 30 years ago. I'm only 33 but when I was a kid, I played outside all day. Running, playing sports, swimming etc etc. Today, many kids sit in their hosues and play video games, or chat on computers. Sugar has always been around. The people are different, the sugar isn't.
Good on you. Glad to hear you were successful and I hope you're just as successful in keeping it off. I was 295+ this time last year, and am presently just under 210. Another fifteen pounds or so will put me in the healthy BMI range, but I intend to keep losing and changing until the body fat percentage is healthy and the fitness is obvious, so if I'm successful I'll probably end in the 180 range.
I went low carb---less than 20g a day (mostly from vegetables) and completely eliminated my cravings for sugar, without much effort on my part, and I stopped craving sweet things. My treat is mixed berries with a couple of tablespoons of heavy cream. I've lost 7 lbs in five weeks.
Epidemiological studies provide trends not absolutes. Whenever a study says that birth weight correlates with the mother's weight and height, it represents a general trend but there are exceptions as in the example of your 10 lb infant.
@obits3 And feeding formula.. though in cases of adopting and foster parenting, that can't be helped. But babies don't need cheerios. They can and should eat soft fruits and veggies tocstart with for solid foods.
I appreciate your input. I'd like it if you'd PM me and let me know more about the way you arrange your diet for health and budget. I do still maintain that there are many reasons why poverty does contribute to obesity (stress being major), but I'm always eager to learn new ways of approaching a problem.
it's not just absense of physical activity or eating too much, hormones have to do with it too! and sometimes it's genetic. there are some people like me who work out and diet yet they can't lose weight b/c they have PCOS or insulin resistance...so NO it's not that simple, other factors play a part too
The problem is not laziness, but lack of knowledge about what to eat. Even the experts can't agree on what a healthy diet really is, so I wonder how anyone else should know. It's not a lack of motivation, but a lack of knowledge about what to do. Think of the thousands of people who starve tons of weight off their bodies just to put it back on again and then starve it off again. That takes work and a lot of motivation.
Plain and simple: Lack of physical activity. Americans drive everywhere. People in other countries ride bikes and walk far more than Americans. The people of other countries eat very similar food. They have soda, candy , chocolate etc. The difference is in the level of physical activity.
I didn't say it was Atkins, never even read the book. I actually began with Protein Power's induction phase and just stuck with it. I didn't see a point in trying to keep a gross amount of carbs in my diet when the deconstruction of triglycerides provides all the glucose I need. You're right, it's not practical at all. I always have to throw away the bun from my burgers.
one thing I don't understand : so if I eat less junk food and exersice more I won't get fit and won't lose weight? if it's not that simple why some people are fit and eat healthy, if it's not personal choice why not every body is fat? are we honest with ourselves or we are afraid of admitting it that the life style we CHOSE is not correct, who's choice is that?
I've been steadily reducing sugar intake over the past two years. It's amazing...I bought into the whole deal of "metabolism slows in the early 30's" but that's a crock. The hard part was the withdrawals and ravenous hunger. It was much worse than quitting smoking.
i took a screenshot of the list of diseases sugar causes, by pausing the video, using Ctrl and + to increase the picture to fill the screen, & 'snip' (windows) to take a .png picture (.jpg pixellates for some reason) and i'm hoping this will motivate me to cut my sugar intake as my new screensaver.
I've always thought a calorie isn't a calorie but the majority want to convince otherwise, which is not correct in my opinion. Well, to some degree, it has a lot to do with the source of the food you eat, not a number of calories. Like, cake v.s. carrots, though in the same amount of calories, cake is more fattening due to its substances. I've gone for the liquid diet all the way for a week and noticed a difference. And if they say liquid's calories and solid calories are the same, not true.
You are 100% correct! I absolutely am eating them in mostly fat (>= 75%) and protein. The glycerol molecules (from triglycerides, a.k.a. "fat molecules") is my source of glucose AND energy. The human body REQUIRES exactly 0 g carbs/day. This is easy to understand because there are NO diseases resulting from a carbohydrate deficiency. There are, however, myriad diseases resulting from fat and/or protein deficiencies, and, as you already know, problems with TOO much carbohydrate intake. :)
Thank you for getting it! Of course, even good education and cooking skills don't overcome all problems that inherently make poverty "fattening". There's a lot to be said about total stress, and the TYPE of stress, as well as facing the same problems in the kitchen pantry as on convenience store shelves. I can only shop for groceries twice a month. I try to buy fresh foods, but must buy foods that will last long-term too. That usually means starch. Also, starches "stretch" meals. What can I do?
I have no idea if this was mentioned, but around 7:22 Dr. Atkin's book is listed with many of the diets that limited FATS, not sugar. If anything Atkin's was on the right path.
I noticed the same thing last time I went to Tennessee for a family reunion. I live in California. I couldn't believe the plethora of lard butts I saw walking around, including within my family. It's really sad. I did not eat most of what was served. I made smarter eating choices ,and not just at that reunion. I do that at home too. For some reason when it comes to food, many people are not mentally strong, and don't listen to their bodies, and they are lazy when it comes to exercise.
They said to cut fat and we got fat. Dr. Atkins said the opposite and his patients lost weight. Now we can finally see them start to re-evealuate the great advice they've been pushing for 40 years plus. Whether you're successful as a vegetarian/vegan or keto/low-carb the true culprit is the same: Easily digestable carbohydrates that raise insulin and turn into fat as soon as the body absorbs them.
Lustig and his colleagues even acknowledge the fact that there are so many hypotheses to choose from that it’s hard to keep track. Seems like in order to address obesity, we’re going to have take a balanced approach by eating less and exercising more. If there’s no one cause that we can point to, then there’s certainly no magic bullet that can fix it.
I used to be 230lbs two years ago. When I saw videos of people starving in Africa, I thought it was immoral of me to be obese and starting to loose weight. I still weigh a hefty 170lbs, but I'm improving. The corporations won't change what they are putting in out food. You have to take initiative and do it yourself unfortunately.
I had to actually get a journal and write down what I eat each day in order to track my calories. I figured out I'm comfortable with an average of 1546 calories a day and exercising 5 days a week. I also eat high protein... And finally I figured it out, but I'll have to journal what I eat for the rest of my life.
I don't know if I would want to journal what I eat for the rest of my life, let alone exercise 5 days a week. But it's good that you found a way with which you feel comfortable.
Because I'm so small and expense every little calories, I have to eat far less than you do and vegetarianism, but it works so well compare to other diets. I'm so close to my prefer weight and size. I feel comfortable at size 2-4. Zero I feel like I would lose too much of my fluff and make me have wrinkles. I rather stay my hobbit-self. :) Not everyone is met to have the same lifestyle. We humans are one of the most diverse creatures on the planet and should be. All this bickering and fighting over food is stupid... just be glad it is there. I sometimes want to shove all these haters of diet diversity and shove them into famine country, see what then. Anyways, I do apologize for any offense with that last statement. I'm so glad and happy that you found something that works for you TheDtfamus89. I agree that a food journal is a very wise thing to do. I do it too. You aren't alone. Best to you on sticking to it. :) Peace be.
It could also have to do with your age. If you are younger you are able to get away with eating more food but staying physically fit. As you age your metabolism slows and you will no longer be able to keep it up.
Snackwells and Fig Newtons make up a tiny portion of the cookie and cracker aisle. Snackwells aren't even very low fat! It is very efficient for the body to store dietary fat. Making fat out of carbohydrates is inefficient and consequently the body doesn't do very much of that (about 5% of overconsumed carb calories can be turned into fat).
You might consider watching it again then, he explain that the "you don't do enough exercise" is not the answer by showing the exemple of 6 month obese kids (that are fed with product loaded with corn sirup).
my amily loved me or showed me love by feeding mean, i have been obese since i was probably 6 years old,in 3rd grade i was over 200 lbs.. i feel so stuck and like there was nothing i could have done to stop it, how could i know at 6 years old that what my family was feeding and doing to me could make me sick and would make me seriously unhappy.. i had no choice n the matter... my childhod was snatched from me and destroyed beore i even had one
I basically realized all this along time ago. Food is made to be addictive. The food the food industry gives us evolves over time to become the kind of food people will buy the most of. And that kind of food will be the most addictive kind. That's why i try to stay away from all processed foods.
Is he an athlete? That is phenomenal. Going by the BMI can be really misleading with folks like your partner, because muscle weighs so much. I saw a list not long ago with people who would be considered obese by the BMI, and they were all athletes in great physical condition. I wish I had 9% body fat!
** That's pretty good for a year and half.. I had a friend who lost about 80 but I believe she lost to quickly because she has a lot of excess skin flab. I thought being younger (she's 19) you're skin would heal better then someone who's older losing that much weight.. but congradulations!!
If you learn to prefer water over anything containing sugar, it will be even easier for you to remain healthy and fit. I used to drink diet soda until I learned that it causes neurological problems.
Nearly everyone believes that, but does the science back it up? I recommend "Why We Get Fat" by Gary Taubes. Just finished it--it blew my mind! And I've read dozens of diet books over the last 20 years or so, so hopefully that indicates something.
Okay, as I understand it, polycystic ovarian syndrome is a cause of obesity, not a result. Interesting. This is the 2nd place I've heard that. Is there a study available that states whether this is a cause or result of obesity? Anybody got a good link to peer-reviewed literature on this?

Wow that is awesome
I am a dietitian and this guy is 100% correct. I do not practice what I was taught in school. Its false
David De Nicola what were you taught
@@grimreaper2773 I am a student in dietary education. My guess is David is educating his patients on a plant-based diet.
If a product says its low in fat then you can guarantee it will be high in sugar. Food labels can be very deceiving. And healthy foods are always very expensive compared to fatty and sugary food, which are so cheap and seem to be everywhere you go.
@Ariel Zades: my buddy got the method from
the public web resource ,>>> *FirstGQ. com*
she have lost over 30 pounds, 21 inches, 8% body fat,
Lynda Murray okay to circumvent that, don’t buy any processed prepackaged foods or any junk food and eat your sugar and fat from natural plant sources.
What are the best foods to eat?
Angie S Which foods are those?
Even Greek yogurt?

I lost 80 pounds counting my calories (1000 less a day = 2 pounds a week), eating GOOD QUALITY food, and exercising. Counting calories does work. You are just look for excuses.
Joe Edwards, Keep it up! I hope you aren't hungry. I am on almost 2000 calories a day, not that I'm really counting, just eating twice a day until I'm full, exercise 2 - 3 times a week on a treadmill and rowing machine for about 70 minutes each time, getting my heart rate to approximately 2.5 resting (resting = 43). I have been doing this for less than 6 months so about 2 lbs a week. Why are my daily calories double yours and I'm losing the same amount of weight each week with only a small amount of exercise? Probably what I am eating and how the body metabolizes it, wouldn't you say? I'm never hungry except before eating of course. No snacks.
It's all about the money folks.
I'm staying on a high fat/protein diet - with no sugar. Works really good.
good fat is limit 20-30 grams per day and protein under 50 gram per day. if you need workout can more protein and also you need good carbs limit because you need energy. NO Bread and pasta is bad carb.
i am doing the high carb ovovegetarian diet. i am satisfied with what I eat and slim. but I don't use table sugar.
so yes for complex carbs and fiber and a big no no for sugars. but fruit is ok (as there's plenty of fiber).
William Rabig jr
References? I just aim to keep the carb low >75 grams per day and eat until satiated .
This is awesome information and it was 10 years ago! I don't even want to know the obesity stats now in 2023. Yikes!
I'm from Norway, when I visited the USA I went into the supermarket and picked out a cereal that looked like it had little suger in it( it was a bit hard to compare since it's not in %', but it was among the better once). I then picked out some low fat milk to go with it. It was so sweet I couldn't stomach it. I forced down a bowl, the rest went in the trash. Back at the supermarket, new reading og labels of a dozen of cereals, came back with what seemed the lowest in sugar, made a bowl with milk. Again I ate one bowl, threw away the rest, it was too sweet to sweet to eat.
After 2 weeks I went back to Norway, but 8 months later I came back to America for a 2,5 month stay. This time I brought with me the cereal I ate in Norway. Bought the low fat milk again, (didn't knew any better back then), and again the cereal tasted sweet. What was going on? This time I could eat it, but it was still way sweeter than back in Norway. It's not like someone poured suger in the box while I flew over the Atlantic. The only thing that was changed was the milk, so I checked it. In Norway, low fat milk is low fat milk, In the USA low fat milk is low fat milk with 37% more sugar. I poured out the milk and gave up totally on cereals at that point.
My diet wasn't great when I was over there. I ate some hamburgers and fries, some pizza and tacos and sandwiches, but since the products was different than the Norwegian once, I didn't knew how to cook with them, so I ended up eating a LOT of cheddar cheese, almonds and apples. Tended to be my evening meal almost every day and sometime during the day too. I also snacked on seeds now and then. Now I was NOT dieting, and ate whenever I was hungry, I still lost 5 pounds during that time. Without thinking about it I had increased my fat intake and, despite some bad meals, decreased my carb intake. And it caused me to loose weight.
So I say Americans probably have a harder time avoiding the sugar products as they are way more abundance than in some other countries, but it's still possible. I did it without even trying. Of course cheese and almonds is not a good long term solution, but the LCHF defiantly helps regulate your appitate and will probably cause you to loose weight.
There are so many cereals here that have zero sugar. Rice Chex, plain Cheerios, Kix, Grape Nuts and on and on.
I'm a bit of a homebody and thought that this will do well for me, since exercising requires a lot of time, effort, and equipment. Weight loss green store tea worked very well for my needs and was an excellent appetite suppressant.
Bella Lo This product looks great.
adding to that is our odd hours at jobs such as driving trucks, working lengthy periods where excess to healthy food isn't available because it's just grab and go. some ppl skip breakfast altogether while others can't seem to put down the fork. ppl are emotionally tied to food, they are socially tied to food. also, mothers who work more than one job or single households where food becomes less of a priority because the emphasis is what doesn't kill me right now is alright to keep doing.
Such a well edited documentary. Calm and reserved. I like it.
for those of you that are over weight watching this video, all it takes is one click, the right mindset, the ability to research what you need and the desire to get it done! if you find what you need you'll be a new you in less than a year! or even far less than that!!!
Lustig says "it hasn't worked" referring to the idea that a calorie from carrots is the same as a calorie from cake. While that may be true, he's also ignoring the fact that Americans haven't even been trying to get their calories from sources like carrots; people in this country do not eat anywhere near the recommended amount of fruits and vegetables.
Not so. Fruit is a simple sugar, unlike refined sugar and cane sugar. The body does not usually have a problem with fruit raising insulin levels. Did you know that sugar is also in vegetables as well? Basically any carn is a sugar. Fruit also helps people get sweet tasting food without as many calories, and it has many vitamins we need.
I think the movie Wall-E is an accurate future for us.
True
I am still watching the movie and ya I'm agree with u..
Just bought hamburger rolls at Costco. By the label you would think you are buying health food. The label contains the USDA food plate, and some bogus statement about how grains are essential for your well being. And no trans-fats of course (did hamburger buns ever have trans-fat?). It is a very sad state of affairs.
And who is head of the USDA? The former governor of Iowa. And whose interests does he represent? That's right, the wheat and corn (HFSC) producers. What a joke.
Nothing wrong with whole grains; the people of Europe have been harvesting them for 40-50,000 years.
@zipit flygirl And that thick dough super cheesy slice of pizza and a large Coke will probably run you 1,000 calories.
@@blaisetelfer8499 Why lie ? Its only about 10000 years. An hour in human existence.
What an awesome documentary. Very informative. I appreciate it
I almost never eat fast food and Im still 30 lbs over weight at least. I do jogging, tennis, bike riding, swimming, weight lifting. I count calories.. I still cant lose this excess fat. Most of it is the flabby kind of fat, not the dangerous visceral kind. But its still very hard. I know some thin people and they dont diet or exercise. Its really frustrating. People dont understand how hard it is to lose weight.
I only drink distilled water triple charcoal filtered and then magnetized.
But why
@@dylanisaac1017 Pretty sure drinking pure H2O (actual distilled water) is harmful for you. You'd have to look it up to verify. Nothing wrong with a charcoal filter though :)
So true... the only person to blame is yourself.... learn proper nutrition and portion control and practice it.... you will get use to it and you will drop the weight.
I was recently in the hospital for and infection due to complications with uncontrolled diabetes and basically forced into a low cal portion controlled diet, by the time my hospital stay was over I was already used to it and have kept eating that way. I have dropped 15lbs in 2 weeks and plan to continue eating like this for good.
This excellent presentation omits a sacred cow--the contribution of rapid growth and increased height to the obesity epidemic. Birth weight is tied to the mother's height and weight before pregnancy. These factors promote higher birth weight and birth weight is correlated with overweight and obesity. Freedman also found that children that are tall at about 8 years of age are 5 times more likely to become obese adults compared to 8 year olds that are shorter than average.

i am doing the high carb ovovegetarian diet. i am satisfied with what I eat and slim. but I don't use table sugar.
so yes for complex carbs and fiber and a big no no for sugars. but fruit is ok (as there's plenty of fiber).
Really good video. That guy has his information well spoken.
Liz, I have worked with several clients who do follow the low fat, high fiber diet. For example, eating Fiber One bars and many other "diet products. It doesn't work for long term sustainable weight loss.
I always check the nutiction facts label on products, and I'm just an 11 yrs. old kid.
You are right. There are so many factors involved in metabolism and weight loss that we are still discovering new things regarding this. The body is a very complex mechanism, more so than anyone has previously realized. And then there's the genetic component...people who were able to hold onto fat lived through famines and thus passed these "fat genes" along.
Documetário espetacular, uma aula muito produtiva🙌👏
Interesting info on a relevant problem - I'm looking forward to see this series. Thanks.
Thank you for this excellent material!
maybe you have a food sensitivity that is causing inflammation... losing weight requires more than exercise and not eating fast food. It is about the TYPE of food you eat. Its about eating real food...not foods with preservatives and junk in them. I totally understand what you are saying though. It isn't easy. It requires research and lifestyle changes. Watch some videos or read some blogs by Dr. Mark Hyman. He has some really great tips that WILL help.
Yes, there are other factors, but exercise and a healthy diet help regulate hormones, insulin levels, serotonin levels, etc. That said, it might not make you a supermodel; however, it will help maintain weight at a reasonable level, unless you have a severe condition, such as brain tumors, etc.
As someone on the Paleo diet now for nearly two decades, I also have kept my weight down ( do have good, healthy muscle and bone mass), my blood serum markers are all inl the right places, and my skin is clear and soft. In fact, despite being in my mid-40s, people routinely mistake me for a 30 year old. So, does what you do work because like me you gave up grains and most sugars? Think about that.
well if you replace the sugary drinks etc with water etc, isn't that just a calorie reduction?
No. Sugar causes a "feel good" response in the reward center of your brain, so you crave more. This is equal to the response delivered by cocaine, heroin, caffeine, nicotine and several deadly-addictive compounds. And the more sugar you eat, the more that is required to get that pleasurable feeling, so your intake multiplies exponentially.
TheYutubesteve "Well i doubt that sugar is addictive."
Your doubts are completely fucking irrelevant.
TheYutubesteve Sugar is addictive
TheYutubesteve No, but didn't you just hear in this video about 60% of Americans DYING because of thier Oreos?
That's why I look mainly at calories, sugars & carbs. Fats are viewed too, but usually when calories are high so are the fats. If you decrease calories, you're also decreasing fats. Fats & calories are twins, If one is high, usually the other is just as high or higher. :) I also noticed that calories aren't always the case of gaining weight, carbs are. I decrease my carbs intake to 70-90g & I lost weight fast. If I were on the stricter end of Atkins (0-50g Carbs.) I would be a size 0 in a month.
Yes but it can be almost always tracked back to what I have mentioned. And yes, Enviromental toxins mainly aditives in junk food. When it comes to insulin resitance that is almost always caused by having more sacharide in your diet than you can handle. I have lost huge amount of weight simply by cuting sacharide (adjusting to the level of the activity), ditching plant oils and eating much more satfat. In two years I have lost 40kg and got tremendous muscle gain.
and expensive. I'm not trying to be negative but there was a time I couldn't afford fruits and veggies and gained a lot of weight. In some places you can buy 3 tomatoes for the same price as 20+ ramen packets. When you need to stretch your money, which are you going to choose?
sorry, the graph for both increases together - i can always mislay the single important fact.
NB top tip if trying to cut the fat but needing the taste hit, something strong tasting like horseradish sauce, not good for you (sugar & fat) but if you put it only on top of your food, not in it, you do use less sugar usually
And last of all. If you are having problems like bad headache after eating sugary food you would do well to have yourself checked up by the doctor. They can actually measure how well your body responds to glucose and insuline and pinpoint the problem.
Saccharides is the correct term used for what anglo-american people are used to call carbohydrates. That is archaic term derived from poor udnerstanding of their chemical structure. The sachs aren't problem on themselves nor is it neccesary to cut them. You nearly have to adjust them depending on your level of physical activity. You can't sit in school/job all day eating bagels and stuff but sure as hell can't go through heavy exercise without having some stockpiled ready to be used.
Could someone explain to me, how does this presented here information that high glycemic index carbohydrates are a major cause of the obesity epidemic in the US reconcile against diagrams of chartsbin . com, which show that fat consumption in the US is much bigger than in most of other countries, while carbohydrates intake percentage is actually lower in the US? I don't understand it.
I can remember when the mantra was: simply take in less calories than you burn (some still are sticking with this). It should have become apparent a long time ago that it's not that simple. The body processes different foods in a different manner. Plus the fact that people fall into different metabolic groups. What works for one does not necessarily work for another. For instance, I need a high activity level coupled with low fat diet, while others can get by with moderate exercise.
I've been on the paleo diet for about a month and have lost 15 pounds and counting!
How's the progress after 8 years?
Babies are fat at 6 months because they are overfed for 6 months...
That should legally count as child abuse
Some babies are born obese.
Type "sumo babies".
Scolecite, It's far more complicated than that.
This is good to hear. I'm sure there are others like yourself who benefited, but this does not validate the diet, nor does it refute the arguments made by medical community re. its dangers. There are always exceptions to each case. There are people who get well from placebo but it does not mean we start using placebo as a treatment medicine.
Question: If Sugar intake has decreased 40% and consumption of animal fats has also been reduced, where have the calories that are making people obese coming from?
I don't think anyone is claiming a magic bullet. But if we can turn the clock back 30 years, that would be a real achievement. Eating like we did 30 years ago would go a long way to bringing that about.
Is jaggery(brown sugar) less damaging than refined white sugar??? Or are they same???
What is his name?
@7:22 why is Dr. Atkins book put in the group with the low fat diets??
what constitutes saccharides? Is it just chocolate, table sugar, white/bleached/flour? It's really hard to cut them out since these foods are literally everywhere and when I eat them I get a tremendous headache....how did you do it? just went cold turkey?
This is a great video. Though it is a little daunting to those who aren't familiar with these facts or a fan of nutritious eating.. However, as a recent vegetarian and having given up fast foods, pastries, and over sweetened coffees and desserts my life has only changed for the better. I've lost 20 lbs with little effort, have clear skin and don't crave obnoxious amounts of foods, fats, or salts/sweets..
Everyone should re-evaluate their diet.
UCSD Grad, Muir college class of 2011
Thank goodness for people like you. Thank you for all your work and enlightenment
I know fast food, and bigger portions have a lot to do with the increase in obesity, but facts are people, these days, are so much lazier than they were 30 years ago. I'm only 33 but when I was a kid, I played outside all day. Running, playing sports, swimming etc etc. Today, many kids sit in their hosues and play video games, or chat on computers. Sugar has always been around. The people are different, the sugar isn't.
That's true. I think what he's trying to say is that the nutrients that may or may not be coming along with matter more.
Good on you. Glad to hear you were successful and I hope you're just as successful in keeping it off. I was 295+ this time last year, and am presently just under 210. Another fifteen pounds or so will put me in the healthy BMI range, but I intend to keep losing and changing until the body fat percentage is healthy and the fitness is obvious, so if I'm successful I'll probably end in the 180 range.
Yes I am fighting back and helping others to fight back for their health.
I went low carb---less than 20g a day (mostly from vegetables) and completely eliminated my cravings for sugar, without much effort on my part, and I stopped craving sweet things. My treat is mixed berries with a couple of tablespoons of heavy cream. I've lost 7 lbs in five weeks.
Did you know that caffeine spikes insulin so it slows weight loss on a ketogenic diet?😉
Epidemiological studies provide trends not absolutes. Whenever a study says that birth weight correlates with the mother's weight and height, it represents a general trend but there are exceptions as in the example of your 10 lb infant.
I am 6"0 and weigh 240 pounds and am 14 with a super deep voice. Does that seem normal or no in the weight department?
@obits3 And feeding formula.. though in cases of adopting and foster parenting, that can't be helped. But babies don't need cheerios. They can and should eat soft fruits and veggies tocstart with for solid foods.
Maybe you should look into reversing that insulin resistance
He is a fighter/semi-pro boxer, and at 6'4 he is considered severely obese by his BMI which is 37.6. I wish I had 9% body fat too. :)
I appreciate your input. I'd like it if you'd PM me and let me know more about the way you arrange your diet for health and budget.
I do still maintain that there are many reasons why poverty does contribute to obesity (stress being major), but I'm always eager to learn new ways of approaching a problem.
it's not just absense of physical activity or eating too much, hormones have to do with it too! and sometimes it's genetic. there are some people like me who work out and diet yet they can't lose weight b/c they have PCOS or insulin resistance...so NO it's not that simple, other factors play a part too
The problem is not laziness, but lack of knowledge about what to eat. Even the experts can't agree on what a healthy diet really is, so I wonder how anyone else should know. It's not a lack of motivation, but a lack of knowledge about what to do. Think of the thousands of people who starve tons of weight off their bodies just to put it back on again and then starve it off again. That takes work and a lot of motivation.
Plain and simple: Lack of physical activity. Americans drive everywhere. People in other countries ride bikes and walk far more than Americans. The people of other countries eat very similar food. They have soda, candy , chocolate etc. The difference is in the level of physical activity.
This is a problem that needs to be solved ASAP. It's getting out of hand

I didn't say it was Atkins, never even read the book. I actually began with Protein Power's induction phase and just stuck with it. I didn't see a point in trying to keep a gross amount of carbs in my diet when the deconstruction of triglycerides provides all the glucose I need. You're right, it's not practical at all. I always have to throw away the bun from my burgers.
Existe un enlace del video en español, subtitulado?
one thing I don't understand : so if I eat less junk food and exersice more I won't get fit and won't lose weight? if it's not that simple why some people are fit and eat healthy, if it's not personal choice why not every body is fat? are we honest with ourselves or we are afraid of admitting it that the life style we CHOSE is not correct, who's choice is that?
I've been steadily reducing sugar intake over the past two years. It's amazing...I bought into the whole deal of "metabolism slows in the early 30's" but that's a crock. The hard part was the withdrawals and ravenous hunger. It was much worse than quitting smoking.
This series is a real eye-opener
i took a screenshot of the list of diseases sugar causes, by pausing the video, using Ctrl and + to increase the picture to fill the screen, & 'snip' (windows) to take a .png picture (.jpg pixellates for some reason) and i'm hoping this will motivate me to cut my sugar intake as my new screensaver.
I've always thought a calorie isn't a calorie but the majority want to convince otherwise, which is not correct in my opinion. Well, to some degree, it has a lot to do with the source of the food you eat, not a number of calories. Like, cake v.s. carrots, though in the same amount of calories, cake is more fattening due to its substances. I've gone for the liquid diet all the way for a week and noticed a difference. And if they say liquid's calories and solid calories are the same, not true.
You are 100% correct! I absolutely am eating them in mostly fat (>= 75%) and protein. The glycerol molecules (from triglycerides, a.k.a. "fat molecules") is my source of glucose AND energy. The human body REQUIRES exactly 0 g carbs/day. This is easy to understand because there are NO diseases resulting from a carbohydrate deficiency. There are, however, myriad diseases resulting from fat and/or protein deficiencies, and, as you already know, problems with TOO much carbohydrate intake. :)
Fructose becomes addictive as well. Besides doing all sorts of bad things to your organs, it eventually rots the teeth by causing cavities.
Thank you for getting it! Of course, even good education and cooking skills don't overcome all problems that inherently make poverty "fattening". There's a lot to be said about total stress, and the TYPE of stress, as well as facing the same problems in the kitchen pantry as on convenience store shelves. I can only shop for groceries twice a month. I try to buy fresh foods, but must buy foods that will last long-term too. That usually means starch. Also, starches "stretch" meals. What can I do?
I have no idea if this was mentioned, but around 7:22 Dr. Atkin's book is listed with many of the diets that limited FATS, not sugar. If anything Atkin's was on the right path.
I noticed the same thing last time I went to Tennessee for a family reunion. I live in California. I couldn't believe the plethora of lard butts I saw walking around, including within my family. It's really sad. I did not eat most of what was served. I made smarter eating choices ,and not just at that reunion. I do that at home too.
For some reason when it comes to food, many people are not mentally strong, and don't listen to their bodies, and they are lazy when it comes to exercise.
They said to cut fat and we got fat. Dr. Atkins said the opposite and his patients lost weight. Now we can finally see them start to re-evealuate the great advice they've been pushing for 40 years plus. Whether you're successful as a vegetarian/vegan or keto/low-carb the true culprit is the same: Easily digestable carbohydrates that raise insulin and turn into fat as soon as the body absorbs them.
Not easily - no study has shown that. You would have to binge eat to excess.
Lustig and his colleagues even acknowledge the fact that there are so many hypotheses to choose from that it’s hard to keep track. Seems like in order to address obesity, we’re going to have take a balanced approach by eating less and exercising more. If there’s no one cause that we can point to, then there’s certainly no magic bullet that can fix it.
I used to be 230lbs two years ago. When I saw videos of people starving in Africa, I thought it was immoral of me to be obese and starting to loose weight. I still weigh a hefty 170lbs, but I'm improving. The corporations won't change what they are putting in out food. You have to take initiative and do it yourself unfortunately.
I had to actually get a journal and write down what I eat each day in order to track my calories. I figured out I'm comfortable with an average of 1546 calories a day and exercising 5 days a week. I also eat high protein... And finally I figured it out, but I'll have to journal what I eat for the rest of my life.
good job!
I don't know if I would want to journal what I eat for the rest of my life, let alone exercise 5 days a week. But it's good that you found a way with which you feel comfortable.
Because I'm so small and expense every little calories, I have to eat far less than you do and vegetarianism, but it works so well compare to other diets. I'm so close to my prefer weight and size. I feel comfortable at size 2-4. Zero I feel like I would lose too much of my fluff and make me have wrinkles. I rather stay my hobbit-self. :) Not everyone is met to have the same lifestyle. We humans are one of the most diverse creatures on the planet and should be. All this bickering and fighting over food is stupid... just be glad it is there. I sometimes want to shove all these haters of diet diversity and shove them into famine country, see what then. Anyways, I do apologize for any offense with that last statement. I'm so glad and happy that you found something that works for you TheDtfamus89. I agree that a food journal is a very wise thing to do. I do it too. You aren't alone. Best to you on sticking to it. :) Peace be.
smart phone apps are an easier way to track calories.
It could also have to do with your age. If you are younger you are able to get away with eating more food but staying physically fit. As you age your metabolism slows and you will no longer be able to keep it up.
Snackwells and Fig Newtons make up a tiny portion of the cookie and cracker aisle. Snackwells aren't even very low fat! It is very efficient for the body to store dietary fat. Making fat out of carbohydrates is inefficient and consequently the body doesn't do very much of that (about 5% of overconsumed carb calories can be turned into fat).
Dr. Atkins said this and sadly I went the other way. It is now hard to break it again and I have to.
Sir! Also tell us about the metabolism of fats(that we eat) in our body especially by our liver....
You might consider watching it again then, he explain that the "you don't do enough exercise" is not the answer by showing the exemple of 6 month obese kids (that are fed with product loaded with corn sirup).
One of the best videos I have seen but it is not just sugars it is the lack of FIBRE
It doesnt work as easy for everybody. I eat very healthy and exercise, Im still overweight. It took me 5 years to lose 85 lbs .
my amily loved me or showed me love by feeding mean, i have been obese since i was probably 6 years old,in 3rd grade i was over 200 lbs.. i feel so stuck and like there was nothing i could have done to stop it, how could i know at 6 years old that what my family was feeding and doing to me could make me sick and would make me seriously unhappy.. i had no choice n the matter... my childhod was snatched from me and destroyed beore i even had one
i weight 47kg i never get fat i eat everything unhealthy i wanna gain weight what to do
I basically realized all this along time ago. Food is made to be addictive. The food the food industry gives us evolves over time to become the kind of food people will buy the most of. And that kind of food will be the most addictive kind. That's why i try to stay away from all processed foods.
Is he an athlete? That is phenomenal. Going by the BMI can be really misleading with folks like your partner, because muscle weighs so much. I saw a list not long ago with people who would be considered obese by the BMI, and they were all athletes in great physical condition. I wish I had 9% body fat!
** That's pretty good for a year and half.. I had a friend who lost about 80 but I believe she lost to quickly because she has a lot of excess skin flab. I thought being younger (she's 19) you're skin would heal better then someone who's older losing that much weight.. but congradulations!!
I know. I was talking more about how long it takes and how fast food is cheap. I know I can buy healthier stuff at the store
If you learn to prefer water over anything containing sugar, it will be even easier for you to remain healthy and fit. I used to drink diet soda until I learned that it causes neurological problems.
My father developed type two diabetes from obesity... God bless.
Nearly everyone believes that, but does the science back it up? I recommend "Why We Get Fat" by Gary Taubes. Just finished it--it blew my mind! And I've read dozens of diet books over the last 20 years or so, so hopefully that indicates something.
great info. i have changed my diet, but why is dr. lustig obese?
Okay, as I understand it, polycystic ovarian syndrome is a cause of obesity, not a result. Interesting. This is the 2nd place I've heard that. Is there a study available that states whether this is a cause or result of obesity? Anybody got a good link to peer-reviewed literature on this?
