I would love to know how they are defining "athletic performance" in this study and how they supplemented protein intake. The nutritional needs of an Olympic swimmer, American football player, cyclist, fencer, powerlifter, etc are nowhere near the same thing.
In the abstract it acknowledges what you're talking about. This biased source, mentions all sorts of pro athletes that are plant based. Strong man, NFL player, and ultra runners. The ultra runners are interesting because plant based probably gives an advantage.
Yeah, I recognize they acknowledged it, but they didn't address it in the abstract. I'm not saying it can't be done, I'm just wondering what their qualifiers are and what their actual approach was. Powerlifters require large amounts of protein intake that can be difficult to obtain from a 100% plant based diet. That could be addressed with plant based supplements, but that feels a little disingenuous to me.
I suppose I could request the full study, but I can't be bothered lol.
Also, by plant-based do you mean that the diet can include meat-based sources of nutrition as long as that's not the main source?
I am not saying that plant heavy diets are bad. On the contrary, I live with one but I still eat meat eggs and dairy and would expect ancient Romans with spending money such as Gladiators to do the same.
Edit. Oh yes, tell me exactly how it works by downvoating me and not providing a source. I forgot that I was not in a place of learning.
