Hi,
Just to be clear, your headline should really be understood as "why some vegans fail", not "why vegans fail in general". Because, clearly, not all vegans do. I always ate a large fraction of grains, when I was an omnivore, vegetarian, and now as a vegan. It's all a question of proportion, and not eating more (or less) than your body needs.
To be honest, I think the pursuit of a "low energy density" diet is quite absurd. I realize that people would pay a fortune for "zero calorie food", but the very notion has always struck me as perverse, in a world where there are still people starving. If people get too fat by eating too much, they probably shouldn't try to find ways to trick their bodies (and most research shows that it doesn't work), but rather look for something other than food to satisfy their cravings. Physical activity is actually a pretty good substitute.
