As a Type1 (insulin dependant) diabetic and in an effort to help control my blood sugars I've been keto for 7 years. At age 50 and 3 months ago I took up road cycling, I've just completed my 1st 100kms solo and fasted. Felt like I could do it again. The next day pulled up great and rode again, then every day until the next w/end where I rode 150kms over two days. Being keto allowed me to do this without eating or even having a gel. Works for me. Fantastic. I love it.
@@happytrails1963 yes both my basal and bolus rates reduced almost immediately as did my A1C (now 4.7%) I notice IS (insulin sensitivity) lasts for approx. 24 to 36hrs after say an hour ride and tbh I'm not particularly hungry after a longer (2 to 3 hr) ride either. For me keto offers lots of benefits, liked reduced insulin use and hunger, with very little in the way of down side.
I was a fat adapted cyclist when I completed the 2019 Cross Florida Ride. I rode 165 miles in a single day in a nearly fasted state. I had been in a state of ketosis for 8 months 6 months prior to the ride. Its an amazing feeling having basically all the fuel you need already onboard. You're essentially bonk proof. Great video and thank you for being well informed prior to making it.
The quality and edits of Jeremy's vids are fantastic, so many subtle additions to bring overall top quality. Love your enthusiasm for life and gratitude/excitement for simple pleasures Jeremy 🙏🏼
I’ve been a keto rider since 2012. Notable food free rides since then : Dunwich dynamo there and back non stop (400k) , and Margate to Penzance non stop (600k) . My attempt at a 1300 k audax food free failed . I’ll try again
Sad inditement of the human race that it even needs said. It’s like hey folks, watch this but don’t be a dick, if your a dick it’s not our problem. We can’t be responsible for how much of a dick you are. Have a nice day 😂
Man, I was born and raised in that area. Wild to see the bike trails and bridges and roads I grew up with in a video on a British cycling channel. This was weirdly special.
I also have hypoglycemia issues. I have spent the last 10 years struggling because i just could not get my internal combustion going. I tried drinking ketones first, because I heard Keto has been recom.ended for epilepsy control, as well as the annoying symptoms of autism Switched to 20 carbs a day after discovering how good the ketones made me feel...and because I wasn't going to suggest something to my son that I wasn't willing to do. HOLY COW. i have so much more energy, I'm bamboozled. A sensation of well being has descended that I hadn't felt since I was 8. Even my posture has undergone a drastic change. It's nothing short of amazing. It's been 4 weeks and I'm down 20 pounds. I don't care whether it's water, because I was definitely swollen and could t shake it. I'm sleeping better, lost my cravings and my thinking is way more clear. Who knew?!? I'm taking this on as a full.paradigm shift. Once I'm recovered from my health issues, sure I'll train.... but that's a long way off. It feels so good.to be getting my life back. ♡
Read my comment above...I did it for over 3 years...never felt better...slept better...no drops in energy when training... lost tons of weight ..good for you.....now just keep it going....
Some people just seriously THRIVE on keto. I'm a young lad with a tad of extra fat, been feeling really low on energy and depressed the last few years. But then I tried doing keto for a month (would've done more but I got cocky and the addiction kicked back in) and I was like a different person. Clearer mind, WAAAY more energy, more will to live. It's still controversial because not everyone benefits like this but among those of us that still have bodies like our ancient ancestors, keto is a life changer (and saver in some cases)
Jeremy, while I have NO interest in trying this myself, I have enjoyed the series. I'm with several others who enjoy your presentation style and find you really enjoyable to listen to. If comments were as pleasant it would be a nice change. The stunt, the tree, the scenery - all very cool. Hope to see a lot more of your work. Oh... and it was nice to understand the Temps and distances for a change! ;)
Nice experiment! I heard about keto diet early last year and started trying it in Feb 2019. In June, I run a marathon on keto without cab loading before the race and gel during the full course. I felt fresh after the race. At least it worked for me too. Just want to provide another sample. 😉
My first comment on GCN video's: I absolutely love your approach which must have required a lot of research and determination. Perfect balance between science and sport. I'm looking forward to your next video. Your enthousiasm is very catching.
What a cracking video! Really fascinating see how he coped with that physiologically. Also, isn’t Jeremy just the coolest most pleasant man to watch and listen to? Chapeau
Great to see Keto and cycling getting the coverage it deserves. I have been on a Keto diet for 12 months, completed a 110mile ride 4 weeks ago. No issues as all. Diet works really well for me, I only carry energy gels for my cycling partner when he fails to fuel :)
Good job :) !! I'm in a uninterrupted keto for 3 years now. It's the best for long days! Like ski-mountaineering, trail running 50k, biking... Only when I do crossfit with HIIT I feel less power. But the rest periods are improved and shorter. I love it for the every day's life, constant energy levels, little hunger, more time between the meals, better focus and sleep. Ability to fast easily.
I got diagnosed with diabetes and high blood pressure about a year ago. I went Keto in order to lower blood sugar and lose weight. The weight came off, the AIC dropped from 7.8 to 4.5 in a few months and my energy went up. I see a lot of BS about going into ketosis with $50 a week drinks and other stuff... cut carbs/sugars and see how your body reacts. I added spinach and bok choy, while eliminating bread, potatoes, sugar and it works... would not do it if I was suffering from low blood sugar, that sounds dangerous. Also it is hell trying to plan meals and do something healthy and low carb... shopping can be a painful experience. Doctor wanted me to go low salt as well, but research I did determined that the US is nuts with the low sodium diets that actually raise odds of heart attacks and strokes dramatically when the entire reasoning for them is that it can reduce your blood pressure "up to 10%". OK, I use other spices and don't worry about it since I was about ready to commit suicide trying to find low sodium food in the supermarket. Rest of the world recommendation is more than double the American Heart association recommendation and European research indicates under 7500mg a day isn't going to do anything bad for you... the blood pressure bit is a symptom, not the problem. Post heart attack patients in the US on low sodium diets DOUBLE the rate of having another heart attack... wtf. Go for a bike ride and chill...
I’d just like to say that this video is so much better than the last. I feel as though this isn’t a ‘Keto is better’ video, but a ‘This is how keto worked for me’. Jeremy, you were quick to defend your last video against my comment, but I truly feel as this video was way more responsible and ultimately more interesting to watch. Good job dude 🤟🏻
Loving this series - I think it’s cool to see how keto effects different people. While it’s not for everyone I’ve been Keto a little over 2 years and feel better than I have in years.... and as far a sun screen- many people (not all) find they burn less
I have lost 100 pounds in the last 8 months in a very strict keto diet. I had some ups and downs and I believe now everything is OK. The main problem was about electrolytes and now I take supplements of Potassium, Magnesium and an appropriate amount of Sodium. It really worked for me and I know I can do better cycling on Keto. I'm 50 years old now and I feel great, much better than when I was 25 (at that time I was stronger and thinner). Before this keto experience I was high carb fueled all my life and it didn't work for me. Not at all: I was fat, tired, with high blood pressure and with a lot of anxiety. Now even my brain works better. Maybe it gonna be some kind of genetic predisposition about the burning of sugar or fat and I believe in that. By the way, thanks for showing us you tried the keto diet and to be sincere what about happened to you. Cheers from Brazil and keep safe.
Great video! I’m glad you made smart and responsible decision due to the heat. Even more glad you shared with viewers that sometimes the right choice is to adjust your targets. There will be new days, new goals. Keep up the good work!
First of all your London Bridge move was awesome. 👍 As for the carb, keto, vegan, ect diet is an individual choice. What working for one my not work for another. You are doing it right thing by test. Being a type 2 diabetic, I go by what my blood sugar meter tells me. And for me, it’s Keto. My morning 30-40 mile rides are done in a fasted mode. Breakfast after ride. Less cramping and bonking then when I use to carb up for a ride. Save riding my friend.
Thank you for putting yourself through this Jeremy. Most impressive experiment and very interesting. Enjoyed the wonderful scenery too. Look forward to the final video.
You need to go Keto for a full 12 weeks to become properly fat adapted. Then repeat your 100-mile ride fasted with only electrolytes. I happily ride for up to 5 hours with no food. Only have to plan for bottle refills. I could probably go longer but I've never tested my limits.
Nick, this is the most frustrating part of his series. He's not yet fat adapted but is espousing negatives and positives of a ketogenic diet. I think his obvious weight loss and increase in watts/kg says more than any anecdotal musings of what he thinks it's doing for him. He thinks cashews are ketogenic for goodness sake.
Michael Rachal cashews have enough carbs to replace spent glycogen used during hard climbs without kicking you out of ketosis (as long as only consumed during exercise). I found a great resource online talking about that years ago, shouldn't be too hard to find. Then you get the benefits of keto while still having muscular glycogen reserves for the hard parts.
Different bodies fat adapt at different rates depending on physiology, sex and sex hormones, and what your prior diet was. To say it takes 12 weeks is silly. I know people who are so fat adapted that they can do keto for a couple days and be in ketosis then switch back to carbs and repeat. High level athletes are especially good at switching. It really depends on the person and their exercise physiology paired with natural cellular metabolism. Myself? I was on keto for 6 months and NEVER became properly fat adapted. My body would sooner convert protein to glucose than use ketones. Bodies vary. His performance was pretty damn good for having just started keto so he’s definitely fat adapted, or he would have burned out way faster. Edit: and by protein I also mean my own muscle.
Did 100mi on just water a few years ago, very similar conditions. Only regret was not replacing salt... vision got a little blurry that last hour or so. Definitely most hungry I've ever been!
Wow! Excellent video. The ride itself was beautiful to watch, but then to see Jeremy’s pragmatism and rationality throughout and after the ride was really good to see. Very much looking forward video 3.
Oh man this has nothing to do with Keto but those are the roads I used to ride when I was at UMASS, 30ish years ago. Brings back some memories! That road next to the Connecticut River up towards Sunderland was sometimes part of the Friday "easy day, maybe ice cream" ride.
I am not an athlete or a biker. I was a fat dude on a weight loss journey. And I used to ride long distances on a 24hour empty stomach. The energy and head clarity it gives you is amazing. You cannot explain in your head what gives you that energy. But the fat you burn IS energy and it is much more efficient than sugar. You don't need carbs for that. I wouldn't recommend it for skinny dudes, but for weight loss it is amazing
I'm skinny (aftet two year on keto diet ) and I can do it too. Even a skinny person still carries a few kilograms of fat and one kg of fat is about 9000 calories.
yes!! That disclaimer at the start meant something good was coming up. The MAF methode (amongst others) suggests there is a middle ground, basically training the aerobe/fat burning system.
Being om keto diet has been wonderful for my asthma. I used to use a puffer (Airomir) one or several times on every ride or run. Now I don't use it at all. I don't bonk the way I used to. I have no more gas and digestive issues. Maybe I'm not as strong in the sprints and climbs as I could have been on carbs. But, then again if I would have an asthma attack on the same sprint or climb the carbs wouldn't help me.
Really looking forward to the next vid..I did Atkins (properly) for almost 3 years..I played football once a week..circuit training twice a week and cycling once a week... Once all the sugars had gone I can honestly say I never bonked and never had more energy. I think ketone basd diets have been misrepresented over the years..people hear Atkins...or Ketone diet and jump to wild conclusions often based on mis information. It is hard to get your head around not needing carbs to train..and in your case (and i really dont mean any offence) you appear to have lost way too much weight so you dont have much of a natural bank of fat to draw from for energy...so I am impressed with how you did....me on the other hand had plenty of body fat to draw on as an energy reserve... I guess you have to understand the end goal of any diet or eating life change ..mine was to lose weight and try and stabilise my blood sugar.. I wish I had carried on but In the UK at the time it was virtually impossible to just pop into a shop and buy a carb free lunch ..or certainly low enough to sustain my ketosis. So eventually I went back to "normal" eating... I have put on a stack of weight.... I am constantly craving sugar or sugar crashing so I am giving ketosis another shot starting Monday. Carbs for me are a bit like smoking... humans never needed them to survive...but once you introduce them to your system you feel you have to replenish them every time you feel the need....get rid of them totally and go back to the human default setting...ie more of a high protein/fat diet and those urges disappear as do the dips and troughs in energy .... its hard to understand until you have done it so I am not surprised you are struggling to get your head round it... but fair play for giving it a go...
Jeremy, I too border on low blood sugar. I also have the metabolism of a hummingbird at 54 yrs old, 5'10", and 130.lbs. This experiment is really fascinating to me. Thanks so much!
Thank you so much for doing this Jeremy, I am profoundly grateful! Unfortunately I suffer ME (chronic fatigue syndrome) and excess weight is a key issue in my particular manifestation of the illness. Further, in the ME community, the keto approach to eating is the only one slated to work for those of us who have issue avoiding excess weight (others have the opposite problem). One of the few able to exercise (with great care), cycling is the only type of exercise I am both able to undertake and actually enjoy and I was enormously concerned that following keto for the past three months, I would not be able to extend beyond short rides. Your two videos have already helped both with ideas/example and all important inspiration and visual proof, that following keto doesn't mean longer rides are simply unobtainable. Thank you and I look forward to the third and concluding video with great anticipation.
Thanks for doing this. I am a fan of keto eating and what it has done for me (reversed obesity and allowed me to do much more activity) I just did a 20 mile fast hike on a small bag of macadamia nuts, passing many much younger people too. I have never been super high output, but keto fueled I can go long and far on very little, or no, food. I am planning some long bike rides now.
Its such a coincidence I started going Keto around the same time this Ketogenic series started in order to lose a few pounds. Found similar results to Jeremy, can keep going longer without fuelling/bonking. Lost 4kg in two weeks, close to losing the HGV sign when going up hill LOL!
I'm on low carb for 4 months, bought my first serious bike 2 months ago and yesterday did my 1st 100 km ride. Being older and somewhat overweight made this into quite a challenge but it felt definitely natural. I drank a lot, made one longer stop and couple shorter ones, ate some 100 gms dried sausages. I'm not very fast so this took me 4h40. All in all, I'm glad I don't have to choose between low carb and cycling.
I do all my riding Fasted now and mostly Carnivore, did something similar back in the 1990’s with Maffetone but did use more sugars on race days. I have found adding Redmonds Salt & potassium citrate to your drinks helps as well as chicken broth cubes and Thermotabs.
Jeremy should do a video on the rails to trails system in Connecticut and Massachusetts. The trails used to be a train line but have been converted to biking and walking trails. It would make for a great epic ride video and deserves more love
Very interesting video. I was a bike racer for over 25 years, but didn't discover the keto diet until years after I retired from the sport, and no longer do long rides, just short, HIIT style workouts now. But I have always wondered how I might have done if I'd known about the keto diet way back then, so I'm glad you made this video. And the reason you didn't bonk is because when you're in ketosis, instead of burning carbs and glycogen, you burn body fat for fuel, and even if you are very lean, you still have way more body fat to burn than you do glycogen. Oh, and in case you didn't already know, cashews are actually relatively high in carbs. Walnuts, pecans and macadamia nuts are the best keto nuts to eat.
Top effort jeremy... wonderful scenery! Regarding my reply in the previous video, it is safe to assume doing 100 miles in ketosis is feasible. While in ketosis not only fat oxidation rates are adaptively increased but also the muscles are supplied with ketones from fatty acid ketogenesis which compensates lower glycolysis rates (Glucose sparing effect thus lower glucose oxidation rate) and so glycogen depletion isn't virtually a problem (way more relevant at higher intensities). Also, some glucose can be produced from gluconeogenic amino acids and glycerol from triglycerides (very mild gluconeogenic effect) which could sustain a minimal degree of glycolysis. Only concern I see is maintaining proper hidration and eletrolyte intake particularly in the heat. Bonking can be real regardless of glycogen status. Did you consider MCT oil? Consuming foods with high-fat content provides inefficient fuel for working muscles because of the extended period of time for digesting and absorbing regular fats. Fat digestion takes longer because fats needs to be appropriately emulsified and solubilized. Fats are then broken down into fatty acids and glycerol, which are then absorbed by the intestines. After this, these fatty acids then need to be reassembled connected with certain proteins to be transported. This process can take a long time so fats don't provide a quick release of energy. Medium-Chain Triglycerides (MCT) however, are a form of fat characterized by shorter than usual fatty acids which are digested and absorbed at a much faster rate instead of relying on nuts or nut butter sandwiches with bacon like you described. A quick supply of energy is essential and these foods will only provide energy within hours after ingestion. Let's hear what experts and pro athletes think in regard to ketosis.
MCT could also lead to "nasty pants" situation. So it may take some time for the body to adjust to absorbing and utilising without the "unfortunate" side affects. Nut butter /MCT mix could be worth a try?
@@charliemackenzie3647 Thanks for your reply. I’ve read about it. Apparently, it’s one of the side effects of MCT oil supplementation. Also, MCT oil can be risky for athletes with certain conditions like diabetes. The price is another disadvantage. A supplement worth mentioning are ketone salts or ketone esters. In this regard, there is a company - HVMN - that has been doing a substantial research in ketone ester supplementation. They are trying to improve synthesis and production scale to make ketone esters as cheap as possible. With an inexpensive ketone ester drink, MCT oil would get outdated. Ketone ester absorption simply surpasses that of MCT oil. However, atm is really expensive and may have side effects as well. There is a rumor that some WorldTour Teams already used ketone esters in water bottles. They play with marginal gains and since ketone ester drink is just a supplement after all, it isn’t considered a bannable substance. Regarding your question, I honestly don't know. Despite my curiosity with nutrition and biochemistry, I never attempted low carb. Nevertheless, could be a solution to allow the body to adjust to the MCT oil by mixing with some nut butter.
Awesome video! What your doing is so hard for so many reasons. Really doubt your body is fat adapted yet even though your in ketosis. It can take weeks. So your body probably isn't burning fat as a fuel efficiently yet but your not supplying any carbs for fuel either. Almonds were a great idea. Maybe one of the nicest things about keto is you dont get the rollercoaster effect from eating carbs. Its just high energy all the time without lows unless you go low on sodium/electrolytes.
Love these videos and part of the reason I now always bring my bike to visit the in-laws in Greenfield, to bike around that area. It is a great place to ride without the craziness where I live. Even though hot there last week, was at least able to get out for a few rides.
I remember my first 100 mile ride on keto. It does feel weird to ride all that way on very little fuel, think I had some cheese and few bits of sausage. Thanks for making this video!
Enjoyed this video - even though I couldn’t imagine sticking with that diet it is impressive to see how you are managing it and are able to pull off that ride. Nice tree duck too!! Looking very trim as well - great work!
@SEAL CYCLE Whoa, someone is a bit insecure little snowflake LOL - It was just a fact, no other meaning behind it. Just something to think about that that big ol' tree was there even before the Independence...
Carnivore is just a zero carbohydrate diet. You are usually in Ketosis on it. I know, but the protein...ideal carnivore diet includes fatty meats, so you are basically eating keto. And without carbs, you have to produce ketones.
This is awesome, I am on the ketogenic lifestyle and getting into the longer rides. It is awesome that I don’t have to worry about having to implement carbs in my life.
Great video, just the right amount of information. Thought it was good vid' then you negotiated that tree like no one I've ever seen before! As the saying goes 'like a boss!'
This has been a great series of videos. I've done keto on and off for years and I'm about ready to get back on it. I'd like to lose 15 quarantine pounds, and just got a new Commencal Meta TR 29 SX that I'm loving after 10 years away from mountain biking. Excited to see how keto works with enduro-style SoCal riding!
Thanks so much for providing this perspective. I have performed up to metric centuries on keto consuming only electrolytes. I am intrigued about going further but with no organized rides or SAGs not brave enough yet. Looking forward to your 3rd segment
Thank you for including that old sycamore tree. Your efforts are appreciated. If asked about diet I say " I am on a see food diet, I see food, I eat it.". Nobody asks. I have been weighing myself before and after rides. I have a standard route that is 32 miles, is fairly flat, temperature is about 70 F, it takes me just about 2 hours and I rarely consume a whole bottle on the trip and I loose two pounds. My average weight is about 158 pounds. I figure this is water weight.
A. G. North of Hartlepool, in the 20% most deprived areas in U.K. Though it has been rated one of the better places to live in UK in some surveys......
I did 5 years of cycling following conventional (high carb) wisdom, and now 5 years as LCHF/keto. I would never go back to high carb. I have completed 4 ultra endurance races as LCHF (although I find I do need some carbs after 1000-1500km). I can easily ride 300km fasted, on just water and electrolytes, at constant power (my FTP is the same as pre-LCHF days). Going LCHF is a lifestyle change, like going vegetarian. It takes a long time to adjust properly and understand what works for you (maybe a year). It’s not something you can fully appreciate or benefit from by doing a test over a few weeks. If you have spent your whole life fuelling your muscles with glucose, you can’t expect to switch fuel to ketones and overnight expect the same results. I had blood tests taken during the high carb 5 years, and the low carb 5 years. The difference is amazing and the results from low carb blood tests are near perfection.
Jason Sypher fair question and I probably used the wrong word I should have said “much improved and consistently within recognised limits for good health”. The main blood markers that change when you switch from high carb (standard western diet) to low carb is cholesterol and triglycerides. I high triglyceride count being a prime indicator of future cardio vascular disease, but the Triglyceride:HDL ratio is key. The closer (or below) one, the better. When I was on a high carb diet it range between 2-4 (elevated risk of heart attack and stroke, 4 was when I wasn’t training much, 2 was when I was training a lot). Since switching to low carb I have been consistently at or below 1.
Trying to figure out my style of eating love this video you’re my favorite presenter please keep up the diet videos I’m in a slump as of recently due to being sick and my diet changing can’t wait for the next one to come out!
Fun fact: cashews are the least keto of all nuts (well if you exclude chestnuts but you get what I mean lol). Go look up the carbs to lipids ratio...you're better off with brazil nuts, macadamia or pecans...as for me, well I'm not a true cyclist. I do cycle as my mode of transportation, enjoy some longer rides here and there, or use cycling as cardio when my legs are shot but not much more. My main sport is boxing and keto fares pretty bad there usually. So I'm a carb guy definitely (plus I'm half-French half-Italian so waddaya expect? lol). Ten years as a vegetarian though, and it works terrific for me!
@@glennoc8585 why bad? They contain way less carbs than cashews. Cashews are like 40% lipids, and peanuts 50%, but in terms of carbs cashews are like 30+% while peanuts have half of that (15+%ish). Peanuts have more protein for the fillin' :-D
@@glennoc8585 but that is the whole point of the keto diet, maximizing the fats while reducing the carbs! That is why I was making the comments about cashews. Peanuts are totally better from a keto perspective.
@@DearSoldierGP for me the carb counting to get into ketosis was hard but there is an easy variant carnivore or zerocarb where you only eat animal products. Animal products (except for dairy) contain no carbs at all. Just eat meat and eggs and you should be fine (and digestion will be fantastic too believe me)
@@DearSoldierGP nothing except for water and maybe electrolytes initially but once you are active you become very insulin sensitive and a banana won't kick you out of ketosis
Would you like to train on a keto diet? Let us know in the comments 👇
hell no, not for long rides anyway. Western MA is looking pretty good these days
As a Type1 (insulin dependant) diabetic and in an effort to help control my blood sugars I've been keto for 7 years.

It's still controversial because not everyone benefits like this but among those of us that still have bodies like our ancient ancestors, keto is a life changer (and saver in some cases)
Omg that's amazing!! Co grants on the life change. I'm also doing keto and am still new and adjusting to fat burning.
Jeremy, while I have NO interest in trying this myself, I have enjoyed the series. I'm with several others who enjoy your presentation style and find you really enjoyable to listen to. If comments were as pleasant it would be a nice change.
The stunt, the tree, the scenery - all very cool. Hope to see a lot more of your work. Oh... and it was nice to understand the Temps and distances for a change! ;)
Nice experiment! I heard about keto diet early last year and started trying it in Feb 2019. In June, I run a marathon on keto without cab loading before the race and gel during the full course. I felt fresh after the race. At least it worked for me too. Just want to provide another sample. 😉
Have been trying keto this summer and have also been surprised with results of training. Can't wait for episode 3. Great job GCN
My first comment on GCN video's: I absolutely love your approach which must have required a lot of research and determination. Perfect balance between science and sport. I'm looking forward to your next video. Your enthousiasm is very catching.
I love the Montague Book Mill! I used to hang out there in college a lot. "Books you don't need in a place you can't find."
What a cracking video! Really fascinating see how he coped with that physiologically. Also, isn’t Jeremy just the coolest most pleasant man to watch and listen to? Chapeau
David D Yep!
Jeza is SO enthusiastic about everything all the time. Like a labrador in human form! It's infectious.
he is mr peanut butter
Great to see Keto and cycling getting the coverage it deserves. I have been on a Keto diet for 12 months, completed a 110mile ride 4 weeks ago. No issues as all. Diet works really well for me, I only carry energy gels for my cycling partner when he fails to fuel :)
did you keep this up? whats your experience been long term?
Really interesting experiment. Plus a beautiful ride and I love Jeremy's style of presenting.
Thank you GCN. I I love the curiosity, passion and generosity that you bring to all of your videos. Much love!
Awesome stunt at 8:50! The fact that you found joy while suffering in the heat is a testament to your positive attitude. Keep rolling, Jeremy!
Expecting the words carbs and keto a lot. Turns out the most used word is HEAT :)
Northeast US has some miserable weather
He rode past my high school! Great to see some beautiful content from western MA :)
Good job :) !! I'm in a uninterrupted keto for 3 years now. It's the best for long days! Like ski-mountaineering, trail running 50k, biking... Only when I do crossfit with HIIT I feel less power. But the rest periods are improved and shorter. I love it for the every day's life, constant energy levels, little hunger, more time between the meals, better focus and sleep. Ability to fast easily.
I got diagnosed with diabetes and high blood pressure about a year ago. I went Keto in order to lower blood sugar and lose weight. The weight came off, the AIC dropped from 7.8 to 4.5 in a few months and my energy went up. I see a lot of BS about going into ketosis with $50 a week drinks and other stuff... cut carbs/sugars and see how your body reacts. I added spinach and bok choy, while eliminating bread, potatoes, sugar and it works... would not do it if I was suffering from low blood sugar, that sounds dangerous. Also it is hell trying to plan meals and do something healthy and low carb... shopping can be a painful experience. Doctor wanted me to go low salt as well, but research I did determined that the US is nuts with the low sodium diets that actually raise odds of heart attacks and strokes dramatically when the entire reasoning for them is that it can reduce your blood pressure "up to 10%". OK, I use other spices and don't worry about it since I was about ready to commit suicide trying to find low sodium food in the supermarket. Rest of the world recommendation is more than double the American Heart association recommendation and European research indicates under 7500mg a day isn't going to do anything bad for you... the blood pressure bit is a symptom, not the problem. Post heart attack patients in the US on low sodium diets DOUBLE the rate of having another heart attack... wtf. Go for a bike ride and chill...
That tree is even older than Dan Lloyd
Poor Dan copping it.
Close run thing
Good one....lol!!
Who is Dan Lloyd
I hear it used to be on the Sycamore Test Team....
I’d just like to say that this video is so much better than the last. I feel as though this isn’t a ‘Keto is better’ video, but a ‘This is how keto worked for me’.
Jeremy, you were quick to defend your last video against my comment, but I truly feel as this video was way more responsible and ultimately more interesting to watch.
Good job dude 🤟🏻
Loving this series - I think it’s cool to see how keto effects different people. While it’s not for everyone I’ve been Keto a little over 2 years and feel better than I have in years.... and as far a sun screen- many people (not all) find they burn less
Really enjoy watching Jeremy's videos I always find him so enthusiastic! Great work GCN team.
I have lost 100 pounds in the last 8 months in a very strict keto diet. I had some ups and downs and I believe now everything is OK. The main problem was about electrolytes and now I take supplements of Potassium, Magnesium and an appropriate amount of Sodium. It really worked for me and I know I can do better cycling on Keto. I'm 50 years old now and I feel great, much better than when I was 25 (at that time I was stronger and thinner). Before this keto experience I was high carb fueled all my life and it didn't work for me. Not at all: I was fat, tired, with high blood pressure and with a lot of anxiety. Now even my brain works better. Maybe it gonna be some kind of genetic predisposition about the burning of sugar or fat and I believe in that. By the way, thanks for showing us you tried the keto diet and to be sincere what about happened to you. Cheers from Brazil and keep safe.
This long-form in-depth type video is awesome! Love the change in pace videos coming out on the weekends, keep it up GCN :)
Jeremy lives in a really beautiful place. Last year I was in keto state on almost all my rides, and I felt good and did several sportives.
Great video! I’m glad you made smart and responsible decision due to the heat. Even more glad you shared with viewers that sometimes the right choice is to adjust your targets. There will be new days, new goals.
Keep up the good work!
Thanks for watching, Jeremy worked pretty hard for this one!
08:46 GCN should make an on-bike limbo competition for their presenters
That caught my eye... I'd have been struggling to get under that tree while off the bike.
this is a awesome series looking forward to next one, also loved the trails and routes wow . thank you great work Jeremy
First of all your London Bridge move was awesome. 👍 As for the carb, keto, vegan, ect diet is an individual choice. What working for one my not work for another. You are doing it right thing by test. Being a type 2 diabetic, I go by what my blood sugar meter tells me. And for me, it’s Keto. My morning 30-40 mile rides are done in a fasted mode. Breakfast after ride. Less cramping and bonking then when I use to carb up for a ride. Save riding my friend.
Thank you for putting yourself through this Jeremy. Most impressive experiment and very interesting. Enjoyed the wonderful scenery too. Look forward to the final video.
You need to go Keto for a full 12 weeks to become properly fat adapted. Then repeat your 100-mile ride fasted with only electrolytes. I happily ride for up to 5 hours with no food. Only have to plan for bottle refills. I could probably go longer but I've never tested my limits.
Yep he's just Making a fool of himself to give carb fanatics a boner
Nick, this is the most frustrating part of his series. He's not yet fat adapted but is espousing negatives and positives of a ketogenic diet. I think his obvious weight loss and increase in watts/kg says more than any anecdotal musings of what he thinks it's doing for him. He thinks cashews are ketogenic for goodness sake.
Michael Rachal cashews have enough carbs to replace spent glycogen used during hard climbs without kicking you out of ketosis (as long as only consumed during exercise). I found a great resource online talking about that years ago, shouldn't be too hard to find. Then you get the benefits of keto while still having muscular glycogen reserves for the hard parts.
Eric Mercer that's good info, thanks. What do you use for electrolytes?
Different bodies fat adapt at different rates depending on physiology, sex and sex hormones, and what your prior diet was. To say it takes 12 weeks is silly. I know people who are so fat adapted that they can do keto for a couple days and be in ketosis then switch back to carbs and repeat. High level athletes are especially good at switching. It really depends on the person and their exercise physiology paired with natural cellular metabolism. Myself? I was on keto for 6 months and NEVER became properly fat adapted. My body would sooner convert protein to glucose than use ketones. Bodies vary. His performance was pretty damn good for having just started keto so he’s definitely fat adapted, or he would have burned out way faster. Edit: and by protein I also mean my own muscle.
Love these videos, can’t wait for the next one!
Thanks!
huge respect and admire your willingness and curiosity to experiment
Been on keto for about 2.5 years. It's really helped my performance. The first 2 months were tough getting adapted but after that it's been amazing.
All that work but equally enthusiastic! Haha! Love your videos man! Jeremy is to GCN who Blake is to GMBN.
Dude this was great info and very interesting
Hope you enjoyed it
Did 100mi on just water a few years ago, very similar conditions. Only regret was not replacing salt... vision got a little blurry that last hour or so. Definitely most hungry I've ever been!
The hardest thing about watching this video is getting distracted from the science by the awesome scenery
Haha!
I road a similar route on Saturday, it's a great ride. Was much much cooler fortunately.
superb couple of videos. Really enjoyed watching these and the level of info is just right. Thanks.
Lawyer: please don't recreate anything on this video
JPOW: I'M TIRED
Really interesting line of videos, looking forward to the next.
Amazing vid full of info and your own experience. Keep up the good work. Can’t wait for the third vid.
Keto reminds me of those guys who convert old VWs to run on vegetable oil.
vegetable oil is not keto, creates inflammation
@@ccamire Trolls be trollin'...
Wow! Excellent video. The ride itself was beautiful to watch, but then to see Jeremy’s pragmatism and rationality throughout and after the ride was really good to see. Very much looking forward video 3.
Glad you enjoyed it!
Oh man this has nothing to do with Keto but those are the roads I used to ride when I was at UMASS, 30ish years ago. Brings back some memories! That road next to the Connecticut River up towards Sunderland was sometimes part of the Friday "easy day, maybe ice cream" ride.
I am not an athlete or a biker. I was a fat dude on a weight loss journey. And I used to ride long distances on a 24hour empty stomach. The energy and head clarity it gives you is amazing. You cannot explain in your head what gives you that energy. But the fat you burn IS energy and it is much more efficient than sugar. You don't need carbs for that. I wouldn't recommend it for skinny dudes, but for weight loss it is amazing
I'm skinny (aftet two year on keto diet ) and I can do it too. Even a skinny person still carries a few kilograms of fat and one kg of fat is about 9000 calories.
yes!! That disclaimer at the start meant something good was coming up. The MAF methode (amongst others) suggests there is a middle ground, basically training the aerobe/fat burning system.
Being om keto diet has been wonderful for my asthma. I used to use a puffer (Airomir) one or several times on every ride or run. Now I don't use it at all. I don't bonk the way I used to. I have no more gas and digestive issues. Maybe I'm not as strong in the sprints and climbs as I could have been on carbs. But, then again if I would have an asthma attack on the same sprint or climb the carbs wouldn't help me.
Looking forward to the next video! Thank you for doing this, love the nerdy content!
Really looking forward to the next vid..I did Atkins (properly) for almost 3 years..I played football once a week..circuit training twice a week and cycling once a week... Once all the sugars had gone I can honestly say I never bonked and never had more energy. I think ketone basd diets have been misrepresented over the years..people hear Atkins...or Ketone diet and jump to wild conclusions often based on mis information. It is hard to get your head around not needing carbs to train..and in your case (and i really dont mean any offence) you appear to have lost way too much weight so you dont have much of a natural bank of fat to draw from for energy...so I am impressed with how you did....me on the other hand had plenty of body fat to draw on as an energy reserve... I guess you have to understand the end goal of any diet or eating life change ..mine was to lose weight and try and stabilise my blood sugar.. I wish I had carried on but In the UK at the time it was virtually impossible to just pop into a shop and buy a carb free lunch ..or certainly low enough to sustain my ketosis. So eventually I went back to "normal" eating... I have put on a stack of weight.... I am constantly craving sugar or sugar crashing so I am giving ketosis another shot starting Monday. Carbs for me are a bit like smoking... humans never needed them to survive...but once you introduce them to your system you feel you have to replenish them every time you feel the need....get rid of them totally and go back to the human default setting...ie more of a high protein/fat diet and those urges disappear as do the dips and troughs in energy .... its hard to understand until you have done it so I am not surprised you are struggling to get your head round it... but fair play for giving it a go...
Awesome video as usual ! Great work JP and GCN !!
DurianRider must be by now editing a react video to this 😂😂
Was looking for this comment.
Actually can't wait for it to be released
Jeremy, I too border on low blood sugar. I also have the metabolism of a hummingbird at 54 yrs old, 5'10", and 130.lbs. This experiment is really fascinating to me. Thanks so much!
Thank you so much for doing this Jeremy, I am profoundly grateful! Unfortunately I suffer ME (chronic fatigue syndrome) and excess weight is a key issue in my particular manifestation of the illness. Further, in the ME community, the keto approach to eating is the only one slated to work for those of us who have issue avoiding excess weight (others have the opposite problem). One of the few able to exercise (with great care), cycling is the only type of exercise I am both able to undertake and actually enjoy and I was enormously concerned that following keto for the past three months, I would not be able to extend beyond short rides. Your two videos have already helped both with ideas/example and all important inspiration and visual proof, that following keto doesn't mean longer rides are simply unobtainable. Thank you and I look forward to the third and concluding video with great anticipation.
Thanks for doing this. I am a fan of keto eating and what it has done for me (reversed obesity and allowed me to do much more activity) I just did a 20 mile fast hike on a small bag of macadamia nuts, passing many much younger people too. I have never been super high output, but keto fueled I can go long and far on very little, or no, food. I am planning some long bike rides now.
This is such a beautiful ride regardless of fuel. Great work showcasing your part of the world :-) Mad skills at 8:47?!?!?
Its such a coincidence I started going Keto around the same time this Ketogenic series started in order to lose a few pounds. Found similar results to Jeremy, can keep going longer without fuelling/bonking. Lost 4kg in two weeks, close to losing the HGV sign when going up hill LOL!
Jeremy's enthusiasm is bloody brilliant, would love to go for a ride with the guy!
I'm on low carb for 4 months, bought my first serious bike 2 months ago and yesterday did my 1st 100 km ride. Being older and somewhat overweight made this into quite a challenge but it felt definitely natural. I drank a lot, made one longer stop and couple shorter ones, ate some 100 gms dried sausages. I'm not very fast so this took me 4h40. All in all, I'm glad I don't have to choose between low carb and cycling.
This is excellent stuff Jeremy, have loved the meto series so far. Keep the good work!
Paul Wieringa ....”keto”...😬
Not too interested in the topic , but as usual, Jeremy made it quite fascinating. Keep up the great content !
this kind of video is awesome. thanks jeremy for doing this
8:45 holy cow, that's some skill
I do all my riding Fasted now and mostly Carnivore, did something similar back in the 1990’s with Maffetone but did use more sugars on race days. I have found adding Redmonds Salt & potassium citrate to your drinks helps as well as chicken broth cubes and Thermotabs.
Jeremy should do a video on the rails to trails system in Connecticut and Massachusetts. The trails used to be a train line but have been converted to biking and walking trails. It would make for a great epic ride video and deserves more love
Very interesting video. I was a bike racer for over 25 years, but didn't discover the keto diet until years after I retired from the sport, and no longer do long rides, just short, HIIT style workouts now. But I have always wondered how I might have done if I'd known about the keto diet way back then, so I'm glad you made this video. And the reason you didn't bonk is because when you're in ketosis, instead of burning carbs and glycogen, you burn body fat for fuel, and even if you are very lean, you still have way more body fat to burn than you do glycogen. Oh, and in case you didn't already know, cashews are actually relatively high in carbs. Walnuts, pecans and macadamia nuts are the best keto nuts to eat.
Top effort jeremy... wonderful scenery! Regarding my reply in the previous video, it is safe to assume doing 100 miles in ketosis is feasible. While in ketosis not only fat oxidation rates are adaptively increased but also the muscles are supplied with ketones from fatty acid ketogenesis which compensates lower glycolysis rates (Glucose sparing effect thus lower glucose oxidation rate) and so glycogen depletion isn't virtually a problem (way more relevant at higher intensities). Also, some glucose can be produced from gluconeogenic amino acids and glycerol from triglycerides (very mild gluconeogenic effect) which could sustain a minimal degree of glycolysis. Only concern I see is maintaining proper hidration and eletrolyte intake particularly in the heat. Bonking can be real regardless of glycogen status.
Did you consider MCT oil? Consuming foods with high-fat content provides inefficient fuel for working muscles because of the extended period of time for digesting and absorbing regular fats. Fat digestion takes longer because fats needs to be appropriately emulsified and solubilized. Fats are then broken down into fatty acids and glycerol, which are then absorbed by the intestines. After this, these fatty acids then need to be reassembled connected with certain proteins to be transported. This process can take a long time so fats don't provide a quick release of energy. Medium-Chain Triglycerides (MCT) however, are a form of fat characterized by shorter than usual fatty acids which are digested and absorbed at a much faster rate instead of relying on nuts or nut butter sandwiches with bacon like you described. A quick supply of energy is essential and these foods will only provide energy within hours after ingestion. Let's hear what experts and pro athletes think in regard to ketosis.
MCT could also lead to "nasty pants" situation. So it may take some time for the body to adjust to absorbing and utilising without the "unfortunate" side affects. Nut butter /MCT mix could be worth a try?
@@charliemackenzie3647 Thanks for your reply. I’ve read about it. Apparently, it’s one of the side effects of MCT oil supplementation. Also, MCT oil can be risky for athletes with certain conditions like diabetes. The price is another disadvantage. A supplement worth mentioning are ketone salts or ketone esters. In this regard, there is a company - HVMN - that has been doing a substantial research in ketone ester supplementation. They are trying to improve synthesis and production scale to make ketone esters as cheap as possible. With an inexpensive ketone ester drink, MCT oil would get outdated. Ketone ester absorption simply surpasses that of MCT oil. However, atm is really expensive and may have side effects as well. There is a rumor that some WorldTour Teams already used ketone esters in water bottles. They play with marginal gains and since ketone ester drink is just a supplement after all, it isn’t considered a bannable substance.
Regarding your question, I honestly don't know. Despite my curiosity with nutrition and biochemistry, I never attempted low carb. Nevertheless, could be a solution to allow the body to adjust to the MCT oil by mixing with some nut butter.
Awesome video! What your doing is so hard for so many reasons. Really doubt your body is fat adapted yet even though your in ketosis. It can take weeks. So your body probably isn't burning fat as a fuel efficiently yet but your not supplying any carbs for fuel either. Almonds were a great idea. Maybe one of the nicest things about keto is you dont get the rollercoaster effect from eating carbs. Its just high energy all the time without lows unless you go low on sodium/electrolytes.
Love these videos and part of the reason I now always bring my bike to visit the in-laws in Greenfield, to bike around that area. It is a great place to ride without the craziness where I live. Even though hot there last week, was at least able to get out for a few rides.
I remember my first 100 mile ride on keto. It does feel weird to ride all that way on very little fuel, think I had some cheese and few bits of sausage. Thanks for making this video!
How many calories did you before and during? I've done 75 with eating a lot, but am not sure if that's the best strategy...
@@ryancjanus Two eggs, some bacon & bulletproof coffee, sounds wrong but it works
Well done Jeremy! I could almost feel the sweat and heat here! Tough as nails!
Enjoyed this video - even though I couldn’t imagine sticking with that diet it is impressive to see how you are managing it and are able to pull off that ride. Nice tree duck too!! Looking very trim as well - great work!
Awesome vid as always JPow ! Great work
That tree is older than the USA...
@SEAL CYCLE Moon landings were faked.
@SEAL CYCLE Whoa, someone is a bit insecure little snowflake LOL - It was just a fact, no other meaning behind it. Just something to think about that that big ol' tree was there even before the Independence...
SEAL CYCLE why so sensitive?
Yep, we love our forestry. Texas many century oaks and the California redwoods are ridiculously old also!
L. K. So was SpaceX! Completely fake.
Very diplomatic Powers. Great job pushing through the heatwave, curious to see the last segment.
Carnivore is just a zero carbohydrate diet. You are usually in Ketosis on it. I know, but the protein...ideal carnivore diet includes fatty meats, so you are basically eating keto. And without carbs, you have to produce ketones.
This is awesome, I am on the ketogenic lifestyle and getting into the longer rides. It is awesome that I don’t have to worry about having to implement carbs in my life.
Great video, just the right amount of information. Thought it was good vid' then you negotiated that tree like no one I've ever seen before! As the saying goes 'like a boss!'
Awesome video, Jeremy! Safety first with the heat but it was a great effort nonetheless 👏 👍
This has been a great series of videos. I've done keto on and off for years and I'm about ready to get back on it. I'd like to lose 15 quarantine pounds, and just got a new Commencal Meta TR 29 SX that I'm loving after 10 years away from mountain biking. Excited to see how keto works with enduro-style SoCal riding!
So nice to see you ride all through central mass. Used to jam those roads every day for a couple years when I lived there!
Thanks so much for providing this perspective. I have performed up to metric centuries on keto consuming only electrolytes. I am intrigued about going further but with no organized rides or SAGs not brave enough yet. Looking forward to your 3rd segment
Thank you for including that old sycamore tree. Your efforts are appreciated. If asked about diet I say " I am on a see food diet, I see food, I eat it.". Nobody asks. I have been weighing myself before and after rides. I have a standard route that is 32 miles, is fairly flat, temperature is about 70 F, it takes me just about 2 hours and I rarely consume a whole bottle on the trip and I loose two pounds. My average weight is about 158 pounds. I figure this is water weight.

8:50 Yeah, that was class.
Watching this video as I'm drinking bulletproof coffee, getting ready for an 80+ mile ride while in ketosis.
How was the ride.?
He said “lights poking through like a disco ball”. Lmfao 😂.
6:56....That endorphin rush! Real cyclists know the feeling
I did 5 years of cycling following conventional (high carb) wisdom, and now 5 years as LCHF/keto. I would never go back to high carb. I have completed 4 ultra endurance races as LCHF (although I find I do need some carbs after 1000-1500km). I can easily ride 300km fasted, on just water and electrolytes, at constant power (my FTP is the same as pre-LCHF days).
Going LCHF is a lifestyle change, like going vegetarian. It takes a long time to adjust properly and understand what works for you (maybe a year). It’s not something you can fully appreciate or benefit from by doing a test over a few weeks. If you have spent your whole life fuelling your muscles with glucose, you can’t expect to switch fuel to ketones and overnight expect the same results.
I had blood tests taken during the high carb 5 years, and the low carb 5 years. The difference is amazing and the results from low carb blood tests are near perfection.
So your ftp hasn't risen in 5 years, despite racing and training?
What constitutes blood perfection? (New to this, serious question)
Jason Sypher fair question and I probably used the wrong word I should have said “much improved and consistently within recognised limits for good health”. The main blood markers that change when you switch from high carb (standard western diet) to low carb is cholesterol and triglycerides. I high triglyceride count being a prime indicator of future cardio vascular disease, but the Triglyceride:HDL ratio is key. The closer (or below) one, the better. When I was on a high carb diet it range between 2-4 (elevated risk of heart attack and stroke, 4 was when I wasn’t training much, 2 was when I was training a lot). Since switching to low carb I have been consistently at or below 1.
Jason Dakin I’m also getting older! I’m 48.
Trying to figure out my style of eating love this video you’re my favorite presenter please keep up the diet videos I’m in a slump as of recently due to being sick and my diet changing can’t wait for the next one to come out!
Fun fact: cashews are the least keto of all nuts (well if you exclude chestnuts but you get what I mean lol). Go look up the carbs to lipids ratio...you're better off with brazil nuts, macadamia or pecans...as for me, well I'm not a true cyclist. I do cycle as my mode of transportation, enjoy some longer rides here and there, or use cycling as cardio when my legs are shot but not much more. My main sport is boxing and keto fares pretty bad there usually. So I'm a carb guy definitely (plus I'm half-French half-Italian so waddaya expect? lol). Ten years as a vegetarian though, and it works terrific for me!
Peanuts are bad but to.be correct peanuts aren't nuts:-)
@@glennoc8585 why bad? They contain way less carbs than cashews. Cashews are like 40% lipids, and peanuts 50%, but in terms of carbs cashews are like 30+% while peanuts have half of that (15+%ish). Peanuts have more protein for the fillin' :-D
@@anthonymarconi761 it too.much.fat for my.liking.I prefer more protein but the carbs is too low.
@@glennoc8585 but that is the whole point of the keto diet, maximizing the fats while reducing the carbs! That is why I was making the comments about cashews. Peanuts are totally better from a keto perspective.
@@anthonymarconi761 I tried them.by found I got tired not enough carbs for me. I don't get much from the keto diet
Been on Keto for 7 month and i'm never going back! Keto is not a diet, it's a lifestyle. And as far as i can see, the most healthy one.
i wanted to try this but what can i eat then? only nuts ,eggs, steak, butter???
@@DearSoldierGP for me the carb counting to get into ketosis was hard but there is an easy variant carnivore or zerocarb where you only eat animal products. Animal products (except for dairy) contain no carbs at all. Just eat meat and eggs and you should be fine (and digestion will be fantastic too believe me)
@@arhu74 thanks i will try it some time but i like bananas when i go cycling. i dont know what i can take then with me haha
@@DearSoldierGP nothing except for water and maybe electrolytes initially but once you are active you become very insulin sensitive and a banana won't kick you out of ketosis
