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.

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.

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.

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 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. ☺️👍👍

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.

The effect may be a evolutionary trait to increase the chance of a starving individual to gather food for survival, and it may be possible to train the body to use that trait to increase at least mental resilience to a measurable level, probably physical resilience as well. Regarding the questions regarding my thoughts on the usage of ketones, i'm pretty unsure as i don't mind caffeine and the like, but i don't really know at what point we should make drugs illegal.

Alright: 1) Our body needs Glucose and Fructose to perform. Glucose to produce straight energy for the muscles and especially for the brain, fructose to free Testosterone, build up Glycogen in the liver and hel rebuild muscle tissue. 2) When the Glucose and Glycogen levels are too low, the brain triggers ketosis to get an alternative fuel for the emergency cases: Ketones, which come with a penalty when used, especially for the kidneys, unlike normal carbs. 3) When carbs are back in the game, those left over Ketones trigger higher production of Glycogen, so the emergency does not happen AGAIN anytime soon. 4) Ketones are there to save the brain, not the rest of the body which can work with Fat and deconstructed muscle tissue 5) A pro athlete might have up to 7 liters of blood. 25 Nanograms of anything won't increase your wattage or range on a climb, let alone anything fast twitch. 6) Finally, Ketones do make you feel more alert and driven so you survive the emergency your body thinks you are in. If you would feel worse, weaker or depressed with Ketones, you wouldn't go out and search for carbs would you?

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.

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.

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.

I've been low carb for 7 years and very low carb (carnivore) for 3 years. Long rides, 300km plus, (primarily in zone 2) not a problem, and ride the next day as recovery is really quick.

Given the price tag, you should try riding in a fasted state with coconut oil (along with nuts or a piece of dark chocolate). After a few hours it feels exactly like you are in ketosis, but I never tested my ketone levels, so it'd be interesting to see how ketone levels change after a dietary change. For this you'd have to do a HIIT session to deplete glycogen and then consume coconut oil. Coconut oil with dark cocoa tastes so much better than airplane fuel.

If your engine is not able to burn it (e.g your mitochondria) your are going to piss the exogenous ketones directly. That s why at first time you find a lot of ketones in your urine but times to times your body consider to burn it instea waste it. You have to go through a process called "keto adaptation" that means you give the time for your mitochondria to have the right enzyme to burn it. It takes about 4 to 6 weeks to be keto adapted and need to be low in carbohydrate non stop moderate protein and high fat. A well formulated keto diet contains good fat (olive oil cocunt oil) a lot of green veggies, salt magnesium are crucial too (bone broth....) Your areg going through a temporary shut dowin in your performance . But for endurance sport it brings a serious advantage to protect your glycogen for very high intensity . And when you are keto adapted you can be more flexible and cycling carbo hydrate time to time. I m on this diet since 6 years and it's sound to be our natural state . Most of the time in leight to moderate ketosis. When you are healthy you don't need profond ketosis. Professeur Jeff VOLEK wrote a great book on performance on low carb.

0.1 mmol/L (your starting level) means that you are not broken by your carbohydrate consumption - 0.0 would mean you may or may not be broken, and 0.5 or higher means you're engaging in a ketogenic diet. I must admit I've never checked my ketone level.

I took the HVMN keytone ester when i rode up Haleakala the second time. Didn't set a PR going all the way up, but I did get quite a few on segments within. The rides were two years apart and there were some "scientific" differences. PR was April, at the start of the season, fresh out of indoor training; second time was October at the end; and 2nd time I was using my Aeroad w/ AXS and a 50|37 and 10-28 and 60mm wheels (not recommended for the descent!) vs. my lightweight climbing bike with a compact. But, at the end of the ride and day after I felt fine. The second time i actually added an extra 40km to the ride and got a few trophies going home including one 2nd overall on a 12km flat segment. So maybe recovery wise my body benefitted from the ester

this is exogeneous ketones (keto drinks); they're not in ketosis stage which should be the case. Once the athletes who took the exogeneous ketones used up their ketones (intake)--their bodies return to carbo or glucose fuel need. But those who are in ketosis i.e., their bodies use body fat as their fuel, they don't run out of ketones as fuel.

I have this feeling ketone put body in panic zone, tricking brain into thinking it needs to store much glycogen in the muscles as possible for survival. Hence slowing the release rate of glycogen until you need it (sprint, big attack etc...) and for those trained with it, brain & body thinking it is in brink of survival, absorbs whatever energy you intake with much higher rate than normal person who is not in ketosis -》 Giving faster recovery times too. Timing of ketone intake and individual physiology would of course been calculated.

I remember screwing up a synthesis once in the lab, and the professor smelled it and told me it was ketones. They smell nice anyway. If you only have a few competitive rides a year, could you get the same benefit by going into ketosis on a ketogenic diet leading up to the race then carb loading just before the race and during it?
