>>10852974dunno, but here's my anecdotal evidence.
I eat one meal a day, have for the last 6-7 years. At first it was drug induced, only appetite when i smoked weed. But now that's just how I am. Never passed out, never felt weak, never had any issues with it. I dont get sick often, maybe once a year.
I've always been kind of weird about eating though. I eat to live, that's all. Food is great, i love the taste and shit, but i dont get hungry like other people it seems, i can ignore it completely, sleep while hungry, forget im hungry if i get busy with work, ect.
