There are several reasons why we suddenly struggle with weight gain, but the main culprit is the changing hormonal balance, particularly the decrease in oestrogen production.
This significantly slows down metabolism: the less oestrogen, the slower our metabolism.
Additionally, the lower oestrogen levels cause a loss of muscle mass. And muscles burn more calories than fat, which means your energy needs decrease. This means that if you want to maintain your weight, you’ll need to eat less than before.
