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

As we age, our metabolism slows down and we lose muscle mass, which makes it harder to burn calories. Hormonal changes in postmenopausal women can also contribute to weight gain.
