We Tried Ketones And This Is What Happened | GCN Does Science

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.

[petinka]

Ollie going after them one by one! Soon he beated them all at GCN. The boss tremble now.

[mnbvcxz]

LOVE the content - more 'Ollie does chemistry" please

[Den_i_am]

Hank is the kind of friend who would never let you come up with a stupid idea and complete it alone! What a legend

US citizen here:

I’m glad cycling and soccer are so popular in England cause the American you-tubers are not very funny typically. It makes learning about things much more enjoyable.

I was all-in on ketones until the end, when Ollie revealed the price. I guess I'll continue to use pancake syrup.

"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)

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.

I love you doing pre- and recaps more often recently! Thats production Quality! …. And I love you wearing your "science-glasses"!

[doxasnob]

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.

[Isaax]

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

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 .

Next do a Bicycle Day special. Recreate the day Albert Hoffman discovered LSD and rode his bike tripping on the first acid trip.

I love when scientific Ollie is activated 😂

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.

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.

[MachielG]

Great work Ollie and Hank. The video I've been waiting for!

[MrStu]

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 !!!

[TheBassallyear]

I'm most impressed that Ollie called it a magazine!
