Күн бұрынKetones have hit the headlines in recent years. There's been a lot of talk of Pro Cycling teams using them at the top races to boost performance and improve their results. Team Jumbo Visma, women's hour record holder Vittoria Bussi, and others have all been very open in their use of the naturally occurring supplement. This gave Ollie the idea: how much quicker could ketones make us up Alpe Du Zwift?

Hello guys, I am a French MD loving sport physiology and triathlon. First I have to say that I enjoy your videos on my turbo-trainer :) Here I have read all 406 comments before commenting myself :) I have no special diet and don't believe in constrained diets for my well being. After a lot of reading I have tinkered with ketones in 2019. It was especially fun to have some experience with it before the hype during the TdF. It gave me some contacts to discuss it with a manufacturer, press and colleagues. I think the safety profile is ok. What work best for me was the recovery. I took a small amount before going to bed. Take a full dose like you did before an all out effort is not a great idea (but I did this mistake the first time I took some too !!) because there is a risk of hypoglycemia. I tried to take a good amount of carbs (like 2 gels) 45 minutes before the start of a 70.3 triathlon and then 30g KE4 30 min before the start with a good flush of sparkling water to wash out the after taste. The protocol was better for me. I did this for curiosity sake since I am mid-pack athlete and feel I have nothing to prove to anyone. The debate around ketones being a PED or not is real question. (In my opinion it lacks the dangerous for health aspect) I hope people shouting against the use of ketones also avoid any form of cafeine around training ;) Also ketones was a subject under scrutiny last year, maybe it has diverted attention from real dangerous PEDs still in use in the world of sports ? I do not stick with its usage because of the complexity of getting some in France and the ridiculous price.

If the workout is intense enough your body will deplete it's tank of Ketones.. I'm not a cyclist, but I'm Ketogenic and do CrossFit and that's one of the things I blood measure: I'll have a ramp up in natural production (double or triple my baseline of 1.0 mmol per liter) then TOTALLY deplete them And drop BELOW 1.0... However, I usually fast for an hour or 3 before I eat (increasing GH levels, Thomas Delauer has a great video about this!) My Ketone levels come ROCKING back and I can be even higher than my normal baseline... But remember I'm following a stringent Ketogenic diet with almost 0 carbs. I can say the mental clarity and feelings are why I love the way of life, and that one is hard to explain. ☺️👍👍

What's been said by individuals within the WT, under high exertion they can deplete that exogenous amount of ketones in as little as 15 minutes. There's a reason some teams spent $100,000 on ketones for a single tour. At that point you're keeping ketones in a typical bidon just to last the day. I'd be surprised if there was anything other than an insignificant amount left in their system.

@Hardcaslte 4 жыл бұрын
It's actually opposite, I have a Hybrid Ford Fusion and the best use of the battery is for steady rolling. You want to use the engine in a limited capacity to accelerate (aka don't floor it) and then when you get up to speed it switches over to battery power to keep the car rolling. That's because it takes a lot of power to accelerate a vehicle, but once you're up to speed it doesn't take much power to keep it moving forward, just like in cycling or anything else. The limitation here is high speed, because let's say at 75MPH the battery doesn't have enough power to hold that speed for more than a very short time, while anything 45MPH or under it can roll on battery power for a good 1+ miles without help from the motor.
@austinshoupe3003 4 жыл бұрын

Then you devise a "test" that is essentially smashing it up a hard effort that almost certainly relied primarily on supra-threshold power. What the heck?

I remember an important yearly race I do every year. Anyway this one year I thought I'd bike to the startline instead of driving for once. It was a hilly hour away by bike from my house and ~560m of climbing to get there. I thought if I went slow I'd just be burning fat so no worries.lol The race started great the 1st hill was fantastic as I was well warmed up. The 2nd Cat 2 started great going along at 18kph in the bunch. Half way up the bonk hit after 1hr40 of very intense racing and I was suddenly down to 12kph(~200W max) and struggled to the finish 40 hilly k's away with nearly the whole field passing me. Terrible! Usually I bonk at the 2hr30 mark which is ok as many other are too so you don't lose too many places. Anyway this was a hard lesson on just how much carbs I burn even when I think I'm biking slowly!

ketoacidosis has nothing to do with normal ketosis: During ketosis, your ketone levels in the blood reach a concentration of 1-6 mM. With ketoacidosis, the blood values reach a concentration of 16-30 mM. This overacidifies the blood - a life-threatening condition. Classic ketosis is not dangerous and can easily be maintained for several months to years. Source: schnelleinfachgesund.de/exogene-ketone/#Ketose_und_Keto-Azidose_8211_Der_Unterschied

Great Video! Exciting to see you test this and experience some of the benefits! I've been using Ketones for cycling fuel for 4.5 years and I don't pay anywhere near $30/serving ((try closer to $6))! The ketones we use are a bio-identical match to what the body produces. I can attest that this alternate fuel source consistently allows me to maintain a higher level of perceived exertion for longer without feeling fatigue, I definitely recover faster, both during rides between hard efforts (HR recovery) and also afterwards (muscle recovery). I ride fasted, fueling only with ketones (no carbs), unless I anticipate a very hard effort and then take a serving of superstarch (low glycemic carbs) and so I can dual fuel on those rides. But 95% of the time I don't include the starch because the Ketones are SO good at providing energy on demand that even hard climbs and sprints don't deplete my energy and I always finish the ride strong! Four years ago I PR'd a century ride in 4h19m after a 30 hour fast just to prove ketones really can provide what your body needs! Simply amazing stuff! The best thing is that I can honestly say i have not bonked once since using this ride fuel! It simplifies my pre-ride routine too. Just shake, drink and go! And the longer you use them, the better it gets!

You can search for Phinney&Volek on googlescholar; theyve had studies with athletes on ketogenic diets and made them ride TT efforts and did muscle biopsies. Result was that fat adapted athletes utilized much more fat on high intensities compared to non-adapted. Hence the theory as far as i know(not specifically that study). Its been somewhat a hobby of mine reading published articles on keto science though im quite unconvinced it has any relevance for the average cyclist. Plus, apart from a handful ultra-endurance runners theres no pro athlete doing such stuff.
@seahog32 4 жыл бұрын
They are not used preferably. They are just a concurrent source of energy to glucose. If present in blood stream, whether exogenous or endogenous, they get used. That covers part of body energy expenditures, hence saves some glycogen (and protein and fat) that would be burned otherwise. Also, the exogenous ketones are absorbed from the bowel using different pathways than the glucose. With the limited amount of glucose that one can absorb before the system gets overwhelmed, mixing ketones with glucose (and fructose) allows for higher energy intake from food per chosen unit of time.

I'm not a cyclist, but I'm Ketogenic and do CrossFit and that's one of the things I blood measure: I'll have a ramp up in natural production (double or triple my baseline of 1.0 mmol per liter) then TOTALLY deplete them And drop BELOW 1.0... However, I usually fast for an hour or 3 before I workout (increasing GH levels, Thomas Delauer has a great video about this!) My Ketone levels come ROCKING back and I can be even higher than my normal baseline... But remember I'm following a stringent Ketogenic diet with almost 0 carbs. I can say the mental clarity and feelings are why I love the way of life, and that one is hard to explain. ☺️👍👍

How about trying to do Keto for a month and test it out in the context of a diet, although then it should be comparing the diets on a 3-4 hour route, not just 45 minutes. Ketones excells in endurance. Meaning you are likely to perform better on a keto diet in a 4 hour race, without a foodbag in the middle of the race than on a carb diet with a foodbag halfway.

Great video and thanks for sharing the results. However not sure if ketones can be used as efficiently by carbs addicts compared to fat adapted. The energy transfer cannot be so automatic. I have increased my FTP by >30% by becoming fat adapted. Usually carb energy needs to be deleted first before jumping to fat, but your body needs to be trained for that. The hybrid example was good but not sure, the energy can be transferred that easily.

My usual ride I about an hour, and normally I feel exhausted when I get home. On keto I feel really fresh in comparison to how I normally feel. I feel like I could do the ride again just after. And on mtb it feels better to. I don't feel depleted of energy as usual.

This was interesting but IMHO would have been MUCH more useful if there had been a longer approach ride at a moderate intensity level, then the climb, and with ketone levels before AND after. Just because you have a circulating level of ketones consistent with naturally induced ketosis, which involves carb depletion, doesn't necessarily mean those ketones will be used much if local carb stores are available. Interestingly, the mood elevation MAY have been due to a carb-sparing shift of the brain's ... and possibly the heart's ... use of ketones as a more primary fuel.

Well meaning but completely flawed. Human physiology has evolved over 4 million years to be ketogenic. Carbohydrates in any form have only been introduced into the human diet in the last 4000 years and actually 400 years ago if you take into account potatoes and refined grains. To the point that we are primarily eating carbs which our bodies can utilise glucose but it causes so many issues. It’s a dirty emergency fuel source and causes most of the chronic diseases we suffer from that didn’t exist 200 years ago. Human physiology has evolved to run efficiently on ketones, our livers produce the 20% of the brains required glucose from fats and this process is called cluco-neogenosis. This doesn’t happen in the presence of digested glucose, nor does ketosite activation. The only times the human body consumes sugars is small amounts of berry’s/low glycemic fruit typically at the end of the summer, which is natural Fructose processed by the liver. Triggering a an insulin spike and that insulin spike signals to our cells to store more energy in the form of fat as nuts for the winter. By eating so much glucose we have an epidemic of insulin resistance and chronic disease. So as an analogy is that the human body runs on diesel and we have forced it to run on petrol. Its also a completely flawed assumption that you need carbohydrates for explosive exercise, wrong on so many levels. 3 years ago I was a carb eater, 16 stone, type 2 diabetic and I was exercising my nuts off on and off the bike. I went ketogenic and I lost all my visceral fat, the diabetes is gone, as is every other issue I had and I’ve put on a stone in lean muscle. I’m clear headed, smarter, stronger and can sprint faster than I ever did in my teens or ride forever without the need to eat or worrying about bonking on dirty carbs.

Not to be disagreeable, but there are any number of studies that place the introduction of starchy foods into the human diet further back than 100,000 years. I'm glad you've become healthier over the last three years, but my own anecdote stands in stark contrast. 30 years of stable weight, endurance sports, and eating carbohydrates like there's no tomorrow. A test with two subjects is indeed flawed, but no more so than a test with just one. Well done on finding a regime that works for you though, keep it up!

Simon Scott hmmmm, grain gathering is proposed from some studies of prehistoric human remains. But nitrogen levels are high indicating that their main diet is carnivore. Based on recent discoverys its now postulated that we are Facultative Carnivores, large red meat nose to tail, if that wasn’t available then smaller mammals and as an emergency food source plants. None of the plants and vegetables we eat today were available even 4000 years ago. Certainly there was NO refined carbohydrates available. Leading academics in this field are rapidly proving this by example and peer reviewed, double blind clinical trials. Reed Dr Paul Saladino’s new book The Carnivore Code. He’s a genius and has broken down all the myths, dogmas and bro-science that we’ve all been told over the last 80 years. If nothing else he uses facts and studies so its worth checking out.

Loanwolfz, well said. I was Omad but have now gone Carnivore Keto and alternate day fasting. I’m never hungry and this eating regiment best mimics how we would have eaten. I never calorie count I just eat within a 6 hour window on my eating days until I feel full. That triggers raised levels of MTOR and insulin promoting a temporary anabolic state post meal to build and heal. Then as levels of MTOR and insulin drop my body enters a natural Catabolic state and I burn body/ingested fats and autophagy can start. Even my arthritis and other inflamatory diseases have gone. I’m 50 and I’m in better shape than most carb eating 20 year olds. There is also NO clinical trial or evidence at all that we need fibre in our diets. None, the original assumption came from an endocrinologists in the 50’s and there have been many studies since all of which showed no benefits to health or bowel movements. In fact a few showed the opposite. I was a huge salad/ carb eating vegetarian. No longer.

One can get into ketosis without using ketone supplements. However, it does take intermittent fasting (which is not easy to do), eating very small amounts of carbs (50 grams or less per day), a high to normal level of protein, fat and water. Get a blood meter that tests ketone levels. You're officially in 'light ketosis' when your blood ketone level reaches a minimum of 0.5 mmol/L. An 'optimal ketosis' level is 1-3 mmol/L. A level of 4-6 mmol/L, is actually a bit high for optimal athletic performance.

I feel good no bonking side effects. I am 70 and was doing this regularly until the lock down due to covid 19. My humble opinion is that one needs to be on a regular Ketogenic diet, generate natural ketones which becomes the primary source of energy for the body. Taking exogenous ketones while still on a high card diet will not be effective because the body has not naturally adopted to using ketones as a main source of energy it still depends on carbs for energy which is quickly exhausted.
