Fluctuations in sex hormones at different stages of reproductive life, such as the menopausal transition, have been suggested as players in weight regulation. Indeed, the transition from a predominantly estrogenic state to an androgenic state characteristic of the menopausal transition contributes to changes in body composition with accumulation of fat and simultaneous loss of lean mass. However, whether these changes contribute to the weight gain remains debatable. Other physiological and psychosocial factors come into play. It is therefore important to offer individualized support with the objective to minimize the risk of weight gain and associated complications.
