I did notice that in a few recent videos - feels extremely contrived to have a little bottle (or pile) of ketones strategically placed. I'd much rather see good brands of sports nutrition or something else that all athletes would need as a sponsor in videos.

Like a bag of sugar from the store

Ari Klau downing them like crazy in his last video was pretty comical. I'm not gonna give any of these guys/gals a hard time for making whatever money they can in this sport. There's so little money going around in triathlon that it doesn't bother me if they are hawking products that are only marginally beneficial at best.

Let me tell you about the ridiculous bank people drop on bike gear to save a few grams of weight or a couple of watts...

agree. 100%. But that's not ingesting something so unknown, if that's the word I'm looking for. And at times, it's carried some controversy. Not sure that I agree it should or where that goes.

cock-up before conspiracy

Just my n=1 but I've noticed zero benefit from them. Tried them off an on the past few years.

Dave Asprey told me if I put ketone esters in my coffee I won’t need to fuel for an Ironman

Ketones are the new Lactigo.

Exactly! People are dropping loads of money on all kinds of things for marginal gains. Why should ketones be individually picked out?

Ketone esters like MH and TO promote are basically BHB and a PPAR antagonist. Specific
PPAR antagonist compounds are banned per WADA. BHB is a metabolic modulator per research papers and if BHB does what is stated in the papers (and what the pros say) I bet will be on WADA banned list soon.

All I know is that it will be Sam Long’s secret weapon to make up for his swim deficit (not making fun of him), Lance swears they work and they increase EPO https://journals.physiology.org/...2/ajpendo.00264.2022[/url]

I really like Aris videos. I didn’t like that segment. I fast forwarded it. I’m torn too and you make a good point they gotta make money. The couple.com thing is funny, the ketone one didn’t seem so much.

Yeah ketones seem to not have enough bang for the buck in my opinion using during exercise. I hear a lot of info about professionals using them but hard to tell how much is marketing and how much are actually seeing value. Pros pushing them doesn’t bother me, gotta make a buck.

I am following this research and if it turns out to be true, could be more interesting: https://www.mysportscience.com/...-esters-increase-epo

My Strava | My Instagram | Summerville, SC | 35-39 AG | 4:41 (70.3), 10:05 (140.6) | 3x70.3, 1x140.6 | Cat 2 Cyclist

To be honest, this thread has made me more interested in researching Keytones than any pro that has mentioned them.

Streisand effect in action.

Same effect I got from beet juice. Nothing.

Didn't the Norwegians specifically call out Ketones on Rich Roll? Something about seeing other pros take them but that it may be counter-productive. Something about how inflammation is desirable

Yep. I watched it because it was sort of adorable. I have a weakness for Ari and he has to hustle to survive, but if a PRO who has substantial money did this, I would unfollow them for snake oil salesmanship.

"FTP is a bit 2015, don't you think?" - Gustav Iden

This stuff is really not well understood. It has been very much in the margins of WADA legality for several years. Until this year most pro cycling teams and pro triathletes were very reluctant to admit to using it. Side effects are likely not well understood / communicated. Long term impacts for sure not well understood. Just shows that too many athletes are still ready to take whatever performance enhancing substances they can get away with. Plus, even if it does actually deliver some benefits this stuff is heinously expensive and it just makes the arms race at amateur level for those with deep pockets even harder to keep up with.

Yeah, it was definitely Ari's downing 4 in a day that put me over. I like Ari plenty. And 100% agree and appreciate the need for sponsorships. Pushing an exorbitantly expensive supposedly "significantly performance enhancing" supplement would not be one I would engage in. I mean if it helps like they're insinuating, that's probably not going to pass.

Ketones probably don’t improve endurance performance. See https://www.ncbi.nlm.nih.gov/...articles/PMC7442417/[/url] for a decent review.

Also please stop promoting non-alcoholic beer. Near Beer will not make the girl at the bar look any prettier.

If they didn’t cost more than printer ink I might have been suckered into at least trying one.

There is emerging evidence that suggests ingestion of ketones directly after exercise increases blood levels of EPO in the hours after exercise by a significant amount. The theory being that chronically ingesting ketones leads to having elevated EPO levels for a few hours/day which leads to greater RBC counts. To my knowledge there hasn't been a study yet that confirmed ketone ingestion actually increases RBC, but it seems worth looking into.

I agree that like any supplement the marketing is annoying, but I also think there is interesting side effects to this one that may actually be the intended effect.

I can confirm they don't work. Took lots of Keystones back in college and my athletic performance was absolute rubbish.
