- Ketones 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?

I always love when Oli gets let loose and can show of his past as a Phd Organic Chemist. He actually knows what is going on instead of just reading something and reciting it.
Yep, GCN tolerating science and letting the nerd in Ollie loose. I wonder if this is the reason he opted out of cycling/marketing weekly. 😂
If only they'd use just slightly more scientific titles for their videos instead of these clickbaity ones. What about "We tested the effects of ketones on a short climb and only found minor improvements"?
@@jan4946 To be honest, your alternative title kind of spoils the video. Sure, it's more accurate, but it makes the video less entertaining, because the results are already spoiled. This is after all, a video that is supposed to be entertaining as well as being informative, as opposed to a study, which has the sole purpose of being informative. Also, the title isn't overly clickbaity. It's not like it's: "We tested ketones, and the results SHOCKED us!!!"
@@rezoanalom9732 you hit the nail on the head with your click baity title. As soon as i read it i got angry ;)
Can't tell if this is totally my style of sarcasm or just a plain talk about him..

LOVE the content - more 'Ollie does chemistry" please
I was all-in on ketones until the end, when Ollie revealed the price. I guess I'll continue to use pancake syrup.
I think pancake syrup will taste a lot better too.
Have a look at MCT oil. It's the same thing at around $15/16oz at whole foods.
Lucas Robinson not the same thing. Similar. Your body still needs to break down the MCFA. The idea of these are you skip the break down step. It actually takes carbs to metabolize fat. Physiologist say “fats burn in the flame of carbs” so when taking MCFA you still need some carbs for the metabolism. With ketones you don’t need any carbohydrate. Wouldn’t it be nice though.
Same here. $89 is waaaaaayyyyy out of my budget. I'll stick with Hammer Nutrition gel.
Just make sure that's pure maple pancake syrup eh? ;)
Hank is the kind of friend who would never let you come up with a stupid idea and complete it alone! What a legend
"Exogenous carbohydrates": aka eating.
You really should start selling GCN branded towels, judging by the amount of spillage under Hank (not to mention under Simon's bike under the virtual Ronde)
llandor they sell towels
@@troycollett8540 To be fair I was thinking they already did, but not using them and instead getting salty water over their fancy bikes (not to mention carpet/floors), that's just not taking care of your posessions (and using a towel would've reminded me to get one)
@@llandor this is a good point. There is probably dramatic value in them sweating all over the place, makes the workouts looks genuine and difficult, which they are, but I would agree that outside of that you definitely want to keep all that sweat off your fancy equipment.
@@llandor That's the thing, they don't own the fancy equipment they're using. They haven't paid for it and they're not going to keep it.
That and a GCN training mat.
I love when scientific Ollie is activated 😂
I love you doing pre- and recaps more often recently! Thats production Quality! …. And I love you wearing your "science-glasses"!

Ollie, you are the best! Your brains are showing, and its great. Love your approach, keep up the great work. I teach some complicated and involved topics and a laugh while you are doing it makes it go down so much easier. I had some good laughs here and learned, finally, what this keto thing is all about.
Great work Ollie and Hank. The video I've been waiting for!
Enjoyed the detail and Ollie doing well.
Hello GCN I love all your videos and wish you all good health in this time of madness
Next do a Bicycle Day special. Recreate the day Albert Hoffman discovered LSD and rode his bike tripping on the first acid trip.
Competence and inherent aptitude to explaining tricky topics. Bravo!
I have hypothyroid AND ADHD. Ketones helps me with feeling normal due to having more energy, puts me in a positive mindset, and somehow it helps with my ADHD. I’ve also heard other people that have ADHD were able to drop their medication for it due to taking ketones. I’ve never taken meds for it, but it absolutely helps.
Extremely well explained. Bravo
I'm most impressed that Ollie called it a magazine!
Love the science, Ollie. More please. Great content!
Ollie ollie ollie !!! Welcome back, that was an interesting and entertaining video. Props to beating Hank
Well done guys. Appreciate the combo of humor and science.
Awesome vid, laughed so hard! As someone who does intermittent fasting I could appreciate being able to get the physical and mental clarity without the hunger.
You were talking about how you felt more positive and ready towards the exercise - this is me on keto all the time. To be fair, it was coming from a very high carb diet with lots of processed garbage, so improvement was guaranteed, but keto for people like me really is a life changer
Just had to explain to my other half that "bonking on the bike " was nothing to do with having sex while riding.
It doesn't??? I guess I've been doing it all wrong, then
Super interesting. Thanks for putting together GCN! Hank should re-do his 24 hour Zwift ride as an additional data point!!
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.

Hi Olie , Ken here , I used to work in a Phenolic resins plant as a lab tech , we used MEK (Methal Ethel Keaton) to clean the lab glassware .
Great video Ollie, I've been very curious about ketones but never enough to actually buy them. I can't say I'm surprised based on anecdotal experience from acquaintances who are on keto diets. A science of cycling show with Ollie wold be great.
Great research doc Ollie and Hank the tank
Those are the two hardest workers at GCN.
Hmmmm, science. High energy nutrition for the mind. Another great Oli video, thank you GCN..
*Was watching your videos and then notification drop*
Very informative. Great video. Typically Ollie humour with great info
You just became my chemistry teachers. Thanks!🤙
You forgot to mention the hour record attempt. Great video, thanks.
Probably worth noting the car engine analogy is actually the wrong way around. The internal combustion engine is most efficient at steady speeds whereas the electric motor is used to accelerate up to speed! The limited capacity of a Prius battery fits pretty well with limited glycogen stores in a human as well.
Pierre Receveaux to my knowledge, priuses aren’t set up like that.
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.
The confusion comes about because purpose built electric vehicles are quicker to accelerate than ice vehicles. You have instant toque because nothing has to spin up.
But as was said above, there are power limits to what a hybrid can put out electronically since it was designed for two system to cooperate.
@@austinshoupe3003 Priuses are set up to use mixed power for high speed acceleration, and flip between electric and gas for low speed (30mph) cruising.
Was satisfied with my 1h11m but now... 90+ rpm? 300w?? Damn. Hats off, mate.
Why is 90+ rpm impressive?
@@mitchellsteindler Because he must have done this on a pretty high gear while being disciplined to maintain that cadence. Can't imagine doing this on the smallest gear. I'm doing Zwift for about 5/6 months now and climbed the Alpe 5 times. Each time I struggle in finding a good rhythm... Which is embarrassing because I already am riding a compact (50/34 & 11/28). Often find myself grinding, reaching 70/75 rpm at most. Personal goal is to climb it within an hour. 45min.. I can only dream that haha.
@@Bertos13 Ditch that 11-28 and get a mountain bike cassette 11-36. I never understood why road bike have to have greater than 1 gear ratios as the smallest ratio. Not everybody weighs 60 kilos and produces 400 watts.
@@cristiansmochina9056 Because roadies. 23T used to be lowest sprocket in the mountain stages of the tour for the pros. Only very recently has cadence been shown to be effective - thanks Lance for that.
@@Stumpy77 Except cadence is only *that* effective if you have an, um, artificially enhanced cardiovascular system. Unless you're putting out fairly serious power, there's not actually a huge advantage to higher cadences.
Really interesting and informative video!
Interesting trial. I'm on a Keto diet and can vouch for improvements in energy and other benefits. Your body does need to adapt to using Ketones on a cellular level over time however so I'm not sure of the validity of taking ketones and getting an immediate return from them when not adapted. Love GCN. Another great video !!!
I‘m on ketogenic diet too. Never felt this good before. Since then, I never had problems with low blood sugar again. Before, I had hypoglycemia on almost every ride.
Ah, hence why they didn't get the Popeye or Hulk effect in their muskles. I wonder if Hank and Ollie would consider changing the experiment to ingesting ketones for a longer duration, say several weeks, if a ketone-manufacturer sponsored them. Or would they decline on account of the taste of the swill? Questions, questions.
Seriously I love it when Ollie gets his nerd on. The science is SUCH a nice complement to the sport
You should have measured your blood levels after the tt to see if your ketone levels dropped in order to see if you utilized it as a fuel source. If levels stayed the same it’s just a placebo?
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.
Yes, I would have liked to have seen this as well. It makes no sense to measure pre ketone levels, and post ketone levels, but then not check levels after the climb.
COME ON OLLIE !
@@cup_and_cone Is that why World Tour riders have an expression of suffering on their faces... it's because they're pouring yucky ketones down the hatch? Kidding! This is kind of like when I finally found out why smoking cowboys have that hard look and screw up their faces when they have a cig dangling off the lip... was just smoke gettin' in the eyes. Lost all the romance for me in an instant.
Thanks guys, that satisfied my curiosity

Pro tip- the finger poker needle goes in the sides of your fingers where there are much fewer nerves than the pads.
I really need those ketones. They have now both beaten my PB.
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!
You should do a video on what the gains are from competition. I.e. doing the course on your own vs with someone else. Supposedly you push harder when training with others. It's a key factor in this test that you don't acknowledge Vs your previous times.
I recently did a 00:49:07 up Alpe de Zwift and I tought I was on top of the world :-D good effort guys !!!
Ketones? I was their drummer in the 60s. I think.
"I think". I feel that's accurate for the 60s
@@mitchellsteindler Mitch, I know I was there, my birth certificate is proof. But....
Ystadcop HA! Winning comment today.
It would be interesting to see to what level you could spike ketone production by diet alone.
Love your vids, especially when y'all are in "GCN Does Science" mode, but I don't get this one. You do a great job of explaining the benefits ketones provide: providing an alternate fuel during long low intensity efforts, preserving precious glycogen for harder efforts. 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? Wouldn't it have been a better test if you had ridden for a couple hours on the flats first at an endurance pace, then gone all out up AdZ?
$89!! Interesting until we heard the price. Wow 😉
Oh this is brilliant. While GCN Does Science I get an ad showing how someone got a bracelet and had a wonderful life, lost a bracelet and their life was terrible, then turned to Feng Shui so they could hock me a bracelet which has
"powerful" stones.
Such wonderful irony...
(I admit I didn't watch all 5+ minutes of blather on the add, but there is an ad I clicked on to see what was actually being sold. Hurry.. it's a sale!)
Si & Lloyd sleeping got me😂😂😂
Great video on the power of placebo effect
Hmm, I understand that your test followed this journal article but, as you also mention yourself, recently Ketones seem to be thought not an instant performance booster but rather as support in "ticking over" efficiently, in recovery. There was quite an interesting article in Pro Cycling a while back where they also mentioned that for grand tour riders it might also help with having an appetit and thus simply being able to eat enough.
yes it's Peter Hespel work
Love the new look, uh, D'Artagnan.
*chuckle*
I have bin on a keto diet for about 4 months now and I don't really see a performance increase it is about the same on and off keto. But I see a difference in how tired I get after a ride. 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.
Having a type one diabetic daughter seeing 4.0mmol keytones in the blood scares me. Great effort as always guys.
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
@@frompong6682 thanks for that was just saying it worried me although I know it's safe in people without diabetes.
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!
Where are you getting your ketones?
@@solomontownsendwhich ketones? Some of us are broke and leaving an affordable option would make a big difference

Good analogy and way to use the proper term magazine instead of Clip.
i'v been doing keto for 3 months, so this was very much interesting for me. i was wondering what would happen if i went on a long ride
Which is worst tasting, Ketone Ester or Malort? That's a vid I'd love to see. Kudos GCN, great stuff.
The mental effects of ketones you described does make some sense after hearing it increases during fasting.
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.
I found this video a lot more interesting than i thought it would, i especially enjoyed the bonking.
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.

Dr Ollie... like Bill Nye the Science Guy, except pushing more watts!! Well done, on an excellent video!
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
Two very smart fellows. Great stuff. Questions to be answered in high performance may be questions like, can ketones be IV fed in glucose or injectable? With oxygen enrichment in sprint packs?
Two friends of mine were involved in the testing for the Oxford University study. The things they had to do sounded brutal.
Glad to hear "grandma's pants" make a comeback 😉

Oli, thee needs to tidy up, tyres and shoes on the mantle piece! Good bit of real science Doc
Ketones are typically considered an energy source of last resort for the human body because of more complex biochemical pathway and lower ATP production than for carbs, fat & even proteins, so what’s the theory that exogenous ketones would somehow be preferentially utilized before carbs?
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.
@@Patrnga Ooh. Re: endurance athletes, I want to know what Mark Beaumont thinks of this!!
@@seahog32 Thanks, informative! That dual absorption pathway brings to mind the interview Emma Pooley once did with a race nutritionist, about the two nutrient transporter aspect in gut absorption: czcams.com/video/2jOYNKTEpdI/video.html
Btw, may I know, on a cellular level, what is the physiological reason that a person, who drinks ketones, and who is used to fasting or the keto diet over a long-term, responds better in terms of ability to produce increased physical effort, as compared to a person who drinks the same amount of ketones but isn't fat adapted?
Thanks, Oli and Hank. Great presentation, very honest, but I don't think the ketone manufacturers will be calling any time soon to get you to advertise for them! Shame, you'll just have to keep making videos on GCN for us!
i think ollie is spending more time looking after his hair than he is after that plant beside the TV.
"all the molecules in ketones are also naturally made by the body" so are steroids 🤔
Or EPO.
And testosterone
But Ketones are food-like and not hormone-like
@@natanbrastap7752 ABSOLUTELY correct. But they do have "hormone LIKE" properties, like protein sparring effects. It's a pretty interesting molecule
@@DreamsOfLegend I don't really know much about them but aren't they (ketones) solely produced when certain hormones like insuline aren't being produced by the body?
Hi, What did your whoop say on both occasions before the climbs? Might have a bearing.
Great video. If I were to find natural sources of ketones, what would I eat?
When I was in ketosis, I would go for long runs and to my absolute awe and wonder, I was fully recovered the day after! This never happens on a high carb diet. Ketosis is fantastic but it’s extremely limiting in terms of what you can eat.
Good to see you guys are still taking social distancing seriously...
Not only is there the potential for placebo effect but training status and readiness but also hydration status, recovery status, the list goes on. There's too much interpersonal variability from day to day to draw any kind of meaningful conclusion. With your background in science, you should know this as well as anybody.
Respect for saying magazine instead of clip.
the advantages - depending on which you use, will help preserve glycogen, dampen muscle stress, perhaps increase endurance, but in a stage race, this could be a big difference. moreover, regular use can have anabolic effects and reduction in fat %
One question id love to know, how does this compare to a normal gel, electrolyte gel and caffine gel as well as when to use each one?
Hi Hank 'n Ollie,
Thank you for this video. If i understood correctly, at low level of exercise we can use our own ketones produced by liver as needed. When the intensity raises we "jump" to carbohydrates process. So, is a high level of both ketones AND carbohydrates in the body can be obtained by any kind of diet ? If not, i think that by creating a non natural state it is kind of doping, not that doping which can make a race horse from a mule but something not that clear. What do you think of that ?
Ollie besting Hank, Proof Ketones work!
bonking !!!! 😂😂😂😂 where am from this translates to getting some engine / legover / geting your end away
Why would cyclists or any sportsman - be taking ketones? They are our body's preferred "brain food" not meant for physical activity
I would love to see when coronavirus will be gone. The biggest gcn challenge ever with for example Ollie,Simon and James they could do something like a tour of europe or reproduce the tour de france. I think this would be epic. And with Gcn filming quality this video will certainly have a lots of vues. So guys maybe worth thinking about it.
I love science!
