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

Menopause changes the metabolism. Calories that used to get spent on the menstrual cycle don’t anymore, and hormonal shifts can cause hunger regulation to change as well. Menopausal women are also older and therefore tend to lead less physically active lives and struggle to significantly change their habits.

All this means that women who eat the same as they used to suddenly start to gain weight, and they have a hard time making the changes to stop/reverse it.
