Neither are cundishuns or drugs. They just mean you have to eat less. Nobody said life was fair. On the one hand, everyone is a unique snowflake and beautiful as they are, on the other they get upset when someone can eat the same food as they do (I know, I know, theoretically) and not gain weight when they do, so it's ok for them to be fat. Different people are different. Different people have different abilities and skills and aptitude. If your body requires less food, then you just eat less, that's all there is to it.
