If weight loss is simply cals in / cals out, why do post menopausal women have a harder time losing weight?

Question

Same goes for older people in general. Is it harder to lose weight because they simply move less? What’s happening that makes weight loss so much harder in 30s and above?

Answer 1

Cals out is more than just “walk X miles, burn F(x) calories, run x miles burn G(x) calories”. Different people have different metabolisms and burn different calories based on a number of variables.
