I am 64 and started riding 30 months ago when pretty unfit. I am very diabetic but my blood sugar and insulin levels are normal (HbA1c of 5.2% to 5.7% so far - aiming at 4.8%) with no drugs for the last 8 years thanks to low carb/keto. In March, I did a 100km Gran Fondo with 1400m climbing, and finished after a bit over 5 hours. I was as strong at the finish as at the start and I didn't have to stop or eat along the way. After finishing, I wasn't hungry and had no stiff muscles. Low Carb/Ket reverses Type 2 Diabetes to the point of no medication and better health in at least 50% of Type 2 diabetics - even if they were on insulin initially. The diet is a no-brainer for diabetics.

I would have to first go back to a high carb diet for a day or two before I do the tolerance test to get an accurate result - something I do not want to do. This is pretty well known in the low carb world. But I only have to be non-diabetic on the diet I am eating - not the diet I am not eating. It is not like I actually need to eat carbs for any reason. One of the definitions of diabetes is a HbA1c of over 6.5% and my last reading was 5.3% so by that definition, my diabetes is reversed.

My experience is that ketosis helps most in HR zones 1 and 2, but not above that, so best for long endurance, but not speed work. It’s amazing for Ironman triathlons and maybe for tour riders. It’s a game changer for recovery since ketosis naturally reduces inflammation.

I have been on the Keto diet twice. The first time I was pretty dedicated to getting into full ketosis that I went both low carb and low protein and never reached full ketosis. I did lose a lot of fat mass but I also lost just as much muscle mass. Although I could go for hours with low intensity activity, I couldn't really keep up with those who were on a normal carb diet. When I re-introduced carbs, suddenly I was the one that was difficult to beat. The second time I tried it it was just after I took up DH MT biking. I really struggled with recovery and I was usually out for 3 days before I could get back on the bike. The following season after re-introducing carbs I could bike back to back days with no problem. I think keto is great for people who need to lose a lot of weight but also maybe those who do long hours of moderate exercise. High carb diets tend to retain a lot of water, and glycogen is stored in both muscle and fat mass. Being lighter will make it easier to ride faster, but there is something to be said for a carb driven fuel system when it come to power. And also recovery is much faster, at least that is what I found.

But I just found that I couldn't get the power and recovery I needed to compete or even just enjoy being active. It could be a personal thing because I prefer to exercise every day as opposed to taking days off for recovery. It could also be the type of sport too. DH biking is very different than road cycling. I am also a skier and I struggled more with skate skiing than DH or classic XC. I didn't run much when I was on Keto but I could see it would benefit a marathon runner over a sprinter. I don't know if professional athletes really go full keto. Keto is great for weight loss though, but not if you have low body fat to start with, because I found that I lost 10lbs in fat but also 8lbs in muscle mass. Yes, I was lighter but I don't know if overall it benefitted my athletic performance. I am not convinced that just being lighter wins the race.

Great vid, thx! I have been doing keto for over a year and a half, lost 50 pounds, and am more active than ever and finally at a good weight at 51. It takes a while to be back to full power when you first start that diet, but after adapted I feel stronger. I have been climbing big western US mountains and power to weight is a major benefit. I can climb a big volcano mountain on very little food. Setting PRs on my bike routinely still. It is not hard to stay on for me, but I understand everyone is different.

Great stuff. I've been keto for about a year now. And I lost 50 lbs and cured my fatty liver, high blood pressure, lowered blood sugar, and a few other ailments.

I find it funny that we need to consult a medical professional to eat high fats but we don't need to consult a medical professional to eat high carbs.

It takes several rides to break your mental limit to push beyond the lactic threshold once on keto, but when you do, your legs just keep churning. I've done a 5 hour ride in zone 3/4 fully fasted, at the end wasn't even hungry.

I'm on keto for ~5 years, never felt better. To avoid infamous performance drop at high intensity, increase your protein intake above normally recommended. Ignore myth that too much protein would kick you out of ketosis. In ketosis glycogen stores are replenished mostly via gluconeogenesis, at expense of dietary protein intake, so you have to eat much more protein to fully recover and avoid breakdown of muscle tissues, especially on workout days.

@Brainjock You sound like a keto-basher fanatic that likes to spread misinformation. You should stop doing that.

I have been doing the Keto during fall/winter months for the last 3 years and am started up again at the beginning of the month. I also think understanding what it is you are targeting and if the diet will support that is very important and often lost. For me, it works great this time of year when I am doing very few hard rides/efforts, I am busy with work, kids are starting up school and the typical pre-winter lull in motivation begins to creep in. 3 important things it does for me: No more winter weight gain that I then have to suffer to drop at the start of the season. Second, I LOVE the foods available on the diet and have gotten comfortable with it at this point which makes staying on the diet much easier. Lastly and most importantly, the mental clarity, mood and semi-euphoric body feeling it creates has been life changing for me! It takes me about a month (the window seems to shrink every year) to feel this way but once I do, it is the best part of the diet! I get way more work done, I sleep better, I wake up easier and my anxiety, stress and depression normally felt over the winter months is no longer an issue. It's not for everyone, I'm not going to preach it to people. But if you do try it, accept it is going to suck for a few weeks but once you truly get into ketosis (clean keto, not dirty), that point of clarity is simply an amazing feeling.

Thanks Jeremy! Good info and something to consider. Ride on, ride healthy!

I really appreciate your comments at the close of the video. I started with a whole foods diet because my acid reflux was creating significant health issues. After a month, I had really dropped some unwanted weight. I stuck with it and dropped 22 pounds. Eventually, I moved to more of a keto diet (not a big change from what I was doing), and the two amazing aspects for me are that I stopped taking antacids as I didn't need them, and have not experienced a bonk since, including on some wicked hill climb days. Even with hard effort, I have the stored energy to keep going. Anecdotally, I would say that if you have struggled with stomach issues eating a high carb diet, consider this alternative.

Very similar experience for me. Loved the video. Thanks for experimenting!

The point is, Ketogenic Diets have been around a long time and there is solid science behind the effects. In the end, it comes down to a sustainable lifestyle for yourself and those close to you.

Thank you for (the effort you put into) this video. I consider now my pre/full/off/winter seasonal variations in performance and nutrition more from a "cetone point of view" - it is just that my body shows me the limits/interactions of both "high carb" (which is not sustainable all year for me in a healty way) and more"cetone like/style" (which is typically during "boarder season" for me) nutrition. @durianrider and others who disagree any "cetone" approches : Numbers are seasonal and teleogic/syncronic - Health (mental and physical) is/should not.

Been on for 2yrs now, I can ride just as hard hungry as I do when I’m full....and no more carb crashes.

You need to try this with a longer ride, 80+ miles or so. A distance like that is ROUGH on keto, trust me.

Been in and out keto for the past 4 or so years and would recommend to give yourself a little more time to get really fat adapted. Having the body produce ketones and being able to fully use them are not the same. But great comparison and definitely looking forward to a next evaluation. Try the same thing after 6 weeks of ketosis and things might look different. Also, the idea that high protein kicks you out of ketosis is kinda a thing of the past. Don't worry about too much protein, you can go as high as 45% protein, 45% fat and 10% carbs, test yourself, every body reacts differently.

Another excellent vid from Jeremy

I just took up cycling this year and was losing weight cycling in ketosis but listened to a lot of advice saying that I had to eat carbs in order to cycle well so I stopped. Since exiting ketosis I've started gaining weight back, lost some of the mental clarity that I had, don't like the fact that I need to eat more during my long rides and my blood sugar (which was a bit high before I started but had normalized while on ketosis) is starting to creep back up. Hats off to JP for tackling a complex and controversial subject; you've encouraged me to take up the keto diet again. Also I would say that I had the same problems sleeping while on a keto diet but I realized that I don't need as much sleep when I eat this way (I go down from about 8 hours needed per night to 6 hours). That in turn makes it easier to wake up at 5am for a ride... :)

I haven't read into Keto diets vs high-carb diets in a long time, but this video made me think of it in a new way. I've got two new categories that I want to find data for now: 1. Is one better than the other for a steady state diet while training to develop cycling fitness? Are certain training zones benefited more than others by each diet, or is one simply better for developing all training zones? If the former, coaches could prescribe diet switches within a long-term training phase in order to target specific gains within a zone! 2. Similarly, are there single day performance gains to be had by maintaining one of these steady state diets and then abruptly (a few weeks) switching to the other? Great video that makes me think. Thanks Jeremy & GCN!

Great video Jeremy. Like you my Total FTP increased and i lost weight. That is great. We could also include 2 benefits from low carbs which is better recovery and no bonking. But the main focus to go low car is better health. Because people are slim and doing lots of exercise they think they are healthy. Healthy is better defined by blood and urine test to cover tg, hdl, white blood cells, lymphocites, red blood cells, liver enzymes, blood glucose, insulin sensitivity, nutrients such as vit b12, iron and especially CRP. The overall analysis will certainly predict if you will get a certain disease. In many low carbs people they have improved many of these biomarkers. Exercise is good but food is the main variable for your health.

​@@bobbyhempel1513 I was the same when I first tried out fasting. That's why I thought about it and did some research on the topic for roughly two years before I had the courage to finally try it. The following are just my opinions, so you don't have to feel you have to take it if you don't want to. No worries. Most people are okay with skipping breakfast once in awhile, so if you are in fairly normal health, you can consider doing this routine first: the 18-6 intermittent fasting routine. 16 hours of not eating means you will eat two meals a day (lunch+dinner) and those two meals will ideally be within 6-8 hours of each other. I always have black coffee to start my day--because any protein intake will stop your fast, so skip the milk/cream--because I do feel droopy and coffee is an appetite suppressant. (I'd go easy on the coffee if you find you start to get shaky hands or a racing pulse.) You can consider trying an early lunch, when you first start out. I wouldn't recommend eating a late lunch; that would KO a beginner. TBH, I actually started with 24-hour fasting first, in the very beginning. So I picked Saturdays for the deed, because I could stay at home and take it easy, and I went on a dinner-to-dinner fast. That means I ate dinner as normal the night before, then skipped breakfast and lunch the next day. I would go take a nap in the afternoon when I was hungriest and weakest, and when I woke up, it was basically time for an early dinner. I did this every week until I could venture to leave the house while fasting, and then eventually, watching other people eat while I was fasting. Took me a couple of months and teeth gritting! Then I eventually tried going to work while fasting. That was very hard at first, but then I found that not eating actually made me feel super alert and switched on. If I may, I would recommended doing a dinner-to-dinner fast and not breakfast-to-breakfast. And that you are not the one preparing your own dinner while you're fasting (that was torturous for me. It was a dumb move). It also helped that I am single and so I don't have to watch other family members eat, when I first started fasting. Not sure how you will tackle that one as perhaps you may live with family members. 🤣 Lastly, if I may add this: 30 mins before you have your dinner again, on the day your break your fast, it would be good to have some kind of protein as a snack, ie nuts or an egg. This tells your body to stop the fasting process, so that the body will not go into some kind of "super nutrient absorption mode" when it senses there is food incoming again (mildly related to what's called "refeeding syndrome"). That would make you gain weight rather easily. And for the fast-breaking dinner, it's easier to tolerate if you avoid carbs that meal, and also eat more protein. This has to do with the spike in production human growth hormone that you'll experience 12 hours in during your fast, which is an effect that encourages muscle production. If you want more information on what I mentioned, you're welcome to contact me. If you don't want to, that is fine too. Thank you for listening. (I am not a medical professional, I just happened to work in a hospital before. Also, if you go online and look up fasting and intermittent fasting routines, you will find roughly the same info as what I've mentioned here. Hope this helps!

Love the video, I've been doing keto and researching it for two years, the number one problem with comparisons on traditional or high carb and keto is that we forget the fat adaptation phase of the mitochondrial mechanism so in layman's terms we are switching from burning gas to burning diesel.... so it takes form 6 to 9 months to switch completely and come back or even better our average performance, one of the benefits is increased metabolic fat oxidation capabilities 😉 so don't quit and maybe do a monthly video update untill you are 100% fat adapted.... 👍🏻www.ncbi.nlm.nih.gov/pmc/articles/PMC6410243/ some research on this.

I have been doing the keto diet off and on for about 2 years now. I have lost over 100lbs doing it. Last year I got into riding my bicycle. I have tried a higher carb intake for riding and also just sticking to keto. For me what I realized was when I am in ketosis I actually can go further and not bonk. The only time I have ever bonked was actually when I was eating carbs. when on keto, before a ride I will drink coffee with MCT oil in it. That extra fat will give me more energy to ride. I also found out that with keto I am not as sore. The only problem I have while riding and doing keto is cramping.

Can you do a 'test' to see the effects of a full plant based diet afterwards? Perhaps using recipes from the plant based cyclist book.

When it works its amazing, the smoothest energy release ever, no lows, just a constant flow of energy. But its hard to get right! A low (not zero) carb lifestyle has benefited me in terms of less joint pain etc. I've lost weight and am fitter than I've ever been at age 50. But I tend to have some carbs before excersise, and bananas during a ride, then protein and fats after. Keeps the weight off but means I'm not relying on those ketones, as if they are not there, and you have no carbs in you, any bike ride will feel like you've done 100 miles before you start! If you trained for months for a race, would you really go out without carbs and some gels etc with you on the big day? You'd have to be very sure of yourself to do that.

Great effort Jeremy. Seems challenging to maintain the require effort for Ketosis. Not on my radar of diets to try at the moment. Maybe in the future for the sake of interest and personal science experiment.

The main benefit of a keto/low carb diet is health not performance. The goal of keto is to lower insuline restance, loose visceral fat, lower chronic inflammation etc... Performance wise, you gain low intensity endurance (good for ultra endurance), but you loose in high intensity performance (not good for sprint), althought I gained back my sprint performance after 6 months into keto.

The low carb approach is erroneous for sports. The reason is fat is a "slow" fuel. While it is correct that ATP yield is much larger for fat breakdown, since every molecule of glucose oxidized yields 36 ATP versus the complete oxidation of a triacylglycerol which yields about 460 ATP (each triglyceride molecule contains three fatty acid molecules (3 x 147 ATP) plus 19 molecules of ATP formed during glycerol breakdown, generating a total of 460 molecules of ATP the body uses a completely different set of enzymes to metabolize glucose and triglycerides. The rate of triglyceride breakdown is much slower and requires more oxygen for complete oxidation. On top of that, fat can only be converted to ATP through aerobic metabolism. Glucose can produce ATP not only aerobically but also anaerobically, through glycolysis. While largely inefficient (2 ATP yield) it can produce massive quantities of ATP all at once without oxygen. In fact, fast-twitch muscle fibers rely on the quick glycolytic pathway to meet high power output the reason lacking myoglobin to process oxygen but fatigue fast unlike slow-twitch muscle fibers which are rich in myoglobin and mitochondria able to breakdown both fat and glucose aerobically. Low carbohydrate diets are just nonsensical for strength sports. Regarding, endurance sports the rate limiting factor is oxygen availability. Our bodies rely on fat on low intensity exercise (up to 80% while walking) because there is enough oxygen available to thoroughly oxidize fat. As exercise intensity increases, oxygen becomes a limiting factor. Our muscles shift energy metabolism to carbohydrate as carbohydrate breakdown uses less oxygen and can be used anaerobically during peak efforts. Most long distance races are actually about speed endurance (unlike ultra distance events which are pure endurance) relying more on glycogen stores like strength sports only a bit less having fat some contribution aswell. The only remote possibility in which ketogenic diet could work are ultra distance races.

That is the result of every test conducted under 4 months... Yet to find any tests conducted longer term. The fact that it's believed you cannot eat carbs in keto shows the limited knowledge out there. I increase my carbs and protein on heavy, threshold session days and weight training days, in turn I also increase the fat intake to maintain my macros. This means you end up with a caloric surplus, but keto allows me to train on a deficit on lighter days, and fast 24/48hrs without giving it a second thought, balancing out my calories through out a full week. What the majority fail to see is the ability to manipulate your macros and not affect your state of ketosis once you are fully fat adapted. No study out there has looked at a properly, fat adapted athlete. Why? Because no athlete is willing to forego 4 months of what they perceive to be under performance.

@AlexeyOsodoev

One thing you get wrong is that there is shift from fat to glucose at high intensity. Yes, proportionally more glucose utilized at high intensity, but quantitatively more fat as well. In ketosis glucose from muscle glycogen stores is utilized as well. Fat oxydation rate bottleneck applies to both glycolysis and ketosis, there is no difference in this regard. Study a lot of people reference as proof of fat oxydation being limit of performance in ketosis was administered with mistakes. high carb and low carb groups protein intake was equal, while low carb group needed higher intake to replenish glycogen and recover. Check recent studies where protein intake and training was adjusted, performance was the same or better.

@@AlexeyOsodoev Yes. Surely some fat is continuously oxidized, but carbohydrate oxidation picks up with intensity. Fat can't fuel properly efforts above a certain percentage of a given VO2max value. It's like an inverse relationship between fat and carbohydrate oxidation rates and exercise intensity. And if you hit a sprint/anaerobic zone there is shift for other energy systems, like the anaerobic glycolysis or the creatine phosphate pathways. Certain people get the notion that the laws of biochemistry can be bent and/or don't apply to them because reasons. While it's true that endurance training increases the muscle capacity to store and oxidize triglycerides even at higher intensities which if additively combined with the ketogenic diet that assumedly increases fat oxidation rates, one could theorize about the potential of such approach. In reality the benefits from both training and keto still wouldn't enclose the difference with proper carbohydrate fueling if performance is the objetive.
