Sure. Although there is a major difference between 2-3 stone too fat and obese. One is a typical westerner; the other a mental disorder.
I’m a naturally fat guy who stays super lean due to my job requirements. (I already have to get a waiver for ejection seat due to being too tall.) I work out a lot and don’t eat when I need to. Often sucks. But it’s discipline.
I hear you. I can’t actually tell how much a person weighs - but if you look like you could be hiding a misplaced three week old ham and cheese sandwich between rolls of fat I won’t be hiring you to sell food for my business.
