I'll readily admit that I'm for from perfect, but in fairness, I am much healthier then most and I am in great shape. Despite what anybody will tell you, as a vegan it is incredibly hard to get everything in your body that you need. It is a lifestyle in itself just to do a sufficient job. And if you're an athlete or care about your physique, the lack of quality protein (and having to obsessively cycle what you're eating to get a full spectrum of poor quality amino acids), you are holding yourself back in a big way.

The ironman triathlon winners are almost always vegetarian, and often vegan.

assuming this is true (I don't know if it is or not but have no reason to doubt you),

how does this apply to your average person that:

1) does not have freakish genetics
and
2) does not revolve their entire lives around their sport and proper nutrition
