The last time I saw my cousin she looked and acted anorexic, meanwhile raving about her new gluten free vegan lifestyle. She looked terrible. My other cousin who suffers from narcolepsy was on the same diet raving about all her new energy while falling asleep at the table. Meanwhile I went from being the fattest person in the family to the most in shape in less than 10 months. I usually jokingly order a side of gluten these days, just to piss the gluten freers off.
Tip for American grocery shoppers: Don't hit the isles. Stay within the vegetable and fruits section, shop there, only there, then leave. That is a healthy diet. Usually there are nuts and meat in that section. Don't be looking for the gluten free potato chips and cookies, that isn't healthy.
