Résumé de l'étude

This study is aimed at women currently going through menopause, either as part of the natural process (physiological menopause) or following hormonal treatment for breast cancer. There are several methods to slow down the weight gain frequently encountered in this situation, to reduce the intensity of menopausal symptoms, and to improve quality of life in this context. In this study, we examine the effectiveness and possible side effects of time-restricted eating (TRE) intermittent fasting (with food limited to 8 hours per day and alternating 16 hours of fasting) compared to a control group. Participation lasts 14 weeks, with an optional follow-up of 12 months from the start of the study. Participants will be randomly assigned to either the intervention group (intermittent fasting) or the control group. In the intervention group, a 16h/8h TRE intermittent fasting is practiced for 3 months. In the control group, the usual eating pattern is continued. The primary objective of the study is to assess the effectiveness of TRE intermittent fasting in terms of weight loss and fat mass, improvement of metabolic profile, menopausal symptoms, and bone health after menopause. We will closely monitor any potential adverse effects.
