Yes indeed. Wine is my Achilles heal, but you're right, even when we're eating real food it can definitley effect us in different ways.

What's interesting is that in the wild, we will never see an obese animal, but domesticate them and suddenly obesity becomes a possibility.

Obesity by the way, is defined as: having excess fat that presents a risk to health, which means so-called skinny people are just as likely to suffer obesity as people who are so-called overweight, because it's the visceral fat that presents the risk to health, not so much the subcataneous.
