> Obesity is a true epidemic and over simplifying the problem is not helping us solve it.

A "Lapalissade". Saying an issue is more complex than its synthesis doesn't make the issue more understandable.

You won't deny we never seen any person in a labor camp or lost on a desert island coming back obese, no matter their genetics.

So yes, everyone is different and for some it is less easy than for others. But obese people should stop trying to make it sound like their body is going against the laws of thermodynamics...
