i can't tell if "veganism" is gaining popularity or if it's just cause my perception, cause i watch a lot of vegan yt vids.  it's certainly moving through the yt fitness community like a virus.
anyway, i've been doing it for a couple months.  it's not that hard for me.  it's kind of fun, actually, trying to work out new things to eat given the "rules".
i don't miss meat at all.  dairy, a bit.
i will NEVER understand people who say "must be hard to get those calories in"... i could eat a million calories of processed grains a day.  people who legitimately believe they "need" animal products also mystify me.  the only thing is, yeah it's hard to get a lot of protein without getting a lot of calories in total... but protein needs are grossly overstated, imo.
one interesting effect: like falcon, my thinning hair recovered a LOT.  i think i have fewer grays, too, but that's a little harder to tell.
