When people reach middle age, the metabolic function of the body is also declining. For example, the fat in meat can't be consumed well, so it can only stay in the body and make us obese. So we can change our eating habits, reduce our meat intake and eat more vegetarian food. It doesn't mean that you have to be a vegetarian to stop eating meat. We want a healthy mix, just to raise the proportion of vegetarian food to a higher level. In this way, combined with scientific exercise, we can lose weight and keep healthy.
