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

Because when you’re postmenopausal, the hormone changes result in your body needing less calories to operate than before, so unless you change your diet you will likely gain a little weight or have trouble losing it.
