Well, I've no excuse, I'm educated (University) and know perfectly well how much and what I should be eating. I'm not in the least unhappy, and while not well-off, I can afford food such as lean meat and good quality vegetables and fruit. I cook very well (IMO), I just EAT TOO MUCH and don't seem to want to reduce the quantity. If I DO exercise (walk or swim) I get ravenously hungry and could eat a horse! I haven't any weird genes or anatomical abnormalities (so far as I know) It's all my fault, and I know I ought to be addressing this. Winter isn't a good time though, the cold makes me want to eat. I imagine it's just that food is available and therefore we eat...and eat...and eat....
