most overweight people I know constantly, and I mean constantly, think about calorie intake const, they berate themselves for a single biscuit, they have done more days restricting calories and exerting huge self control than most normal weight people ever have.
I'm sorry but this is absolute arse. Speaking as a person with a long history of eating disorders, who has spent years living with various overweight people, they don't spend 1/1000th of the time thinking about calories than I do, or other skinny people.
Most of the overweight people I've lived with (including but not limited to immediate family members, husband/boyfriends, flatmates, colleagues) will eat a packet of biscuits, nuts, cheese, bread, crisps, etc without thinking twice about it. Hardly 'berating themselves for a single biscuit'. I can't count how many times I've been the only person in meetings who doesn't take a biscuit (or three) from the plate when it's passed round. Most people exert very little, if any, self-control.
Just because you may think about yourself this way doesn't mean it applies to all other overweight people.
