does your friend take supplements?
I don’t think so, not in the conventional weightlifter/bodybuilder way anyway.
There’s a bit of an in joke with vegan weightlifters with “Death Shakes”.
It’s a sort of contest to see who can come up with the best protein shake, usually involving peanut butter, hemp or pea protein powder, flax oil and stuff like that.
Joni’s diet philosophy for weightlifting is pretty much the same as mine for cycling. If you eat plenty of everything you like, you’ll end up with enough of what you need.
According to my Garmin, so probably not accurate, I’ve used 11000 Kcal during 12 hour races and 15000Kcal during 24 hour solos as a vegan.
No supplements, just huge quantities of bread, vegetables and fruit.
