I am one of the "eat whatever shit in a big quantity and never gain weight" people, and I think you may have a point. After discussing it turns out if you add anything I don't eat that much.

First, I never eat in the morning. And I mean never, I can't eat after waking up, I always need a few hours before being able to eat without being disgusted, I know it's bad but I don't think it has an effect really (I don't do it since I'm like 12 or 13).

Second, I NEVER eat between meals. I don't do snacks, unless someone give one to me or whatever, but you get the point, I don't fucking eat some chocolate bar everyday at 4pm, or eat chips all day because I'm bored.

I often only eat good food, or what I think is good food at least. I never use the microwaves, always buy "fresh" meat, eat vegetables aswell (only recently, not when I was a teenagers).

So in the end, I may eat like a savage during the meal earning my reputation, but in the end I don't really eat a lot of shit.

Anyway since I watched Fed Up I understand while US kids are obese. Their public cafeteria in school literally are fast food. Not to mention the retards crying out for freedom when the gouvernement even think about taking action into kids diet.

I won't even start on the sugar and science thing because it sound very threatening but I don't know enough to judge how accurate it is, even though I have no doubt it's very likely given history (hello smoking industry).
