Vegans before and after they began their diet, what do they look like? My search revealed most all vegans look pretty healthy after. One kept showing up that featured an extensively skinny woman, to me she looked like she was pushing her weight loss to far, but maybe I'm wrong. Overall, statistically the vegan diet is better for most everyone who tries it. People lose weight, their skin clears up and the feel better. It's a bonus that it helps the environment and animals alike (less forced breeding/needless slaughter). Basically not being a Vegan is like driving an electric car or living off solar energy, it's great for everyone. Seriously.
