It's not so much the actual calorie count for one of these things so much as it's what those calories are composed of. Doughnuts are bad. I love 'em, but they are sufficiently bad that I'll eat maybe half a dozen a year and acknowledge that's too many. Personally, I'll make my dietary indulgences from better prospects. If you're trying to correct a serious dietary related problem, then incorporating foods like donuts and fried chicken is pretty stupid. It's not about "food police" or "health nazis", rather, making intelligent choices as an adult interested in living a decent life. How long until obesity gets classed as a mental disorder as well as a medical one?
Simple glazed Krispy Kreme donut. Nothing fancy.
