Hello,
I just read a survey about weight and vegans, where more than 50% of those who replied answered that they were overweight.
Maybe many people with weight problems go vegan in the hope that this will reduce their weight, or maybe people who experience side effects of eating too much switch to a vegan diet, and still don't manage to lose weight. The survey doesn't surprise me, but it makes me think that the studies I've seen about vegans and health would be even more convincing if it would cover only people who went vegan without a weight or health problems background.
The perfect study about the effect of a vegan diet would be of course be one that studied people who never had been eating animal products.
