Uh. No? Where are you getting this? Seriously. People like you spout theories like this as though they are gospel truth, but you have literally nothing to back this up.
Not to mention--you are treating being overweight as though it is a literal crime.
Being 100 pounds overweight is not an actual crime! It is not immoral!
How would you even tell if someone is 100 pounds overweight vs 50 pounds vs 10 pounds!
100 pounds "overweight" means ?????
I am in fact very, very fat and most guys have no damn clue because they are too busy staring at my giant tits.
You literally cannot tell a woman's weight from looking at her. You only think you can.
So get the fuck over it.
