Is weight loss effective during menstruation

In theory, weight loss during menstruation may slightly improve fat metabolism efficiency, but it is not advisable to deliberately pursue results.

During the luteal phase to the beginning of menstruation in women, there may be a slight increase in basal metabolic rate. This is due to changes in progesterone levels leading to an increase in body temperature, which in turn increases basal energy expenditure. At this stage, the daily calorie expenditure is about tens to 100 calories more than during the follicular phase, but this difference has limited impact on overall weight loss. Deliberately increasing exercise or reducing diet may lead to endocrine disorders. During menstruation, the body is in a state of blood loss, and excessive restriction of calorie intake can easily lead to discomfort such as anemia and dizziness.

Some women gained weight due to water and sodium retention in the premenstrual period, and the false appearance of weight loss may be caused by water excretion after menstruation. But this belongs to fluid changes rather than fat reduction. A very small number of people may naturally reduce their food intake due to decreased appetite during menstruation, but this situation varies from person to person and is uncertain, and cannot be used as a universal weight loss plan.

During menstruation, it is recommended to maintain moderate exercise such as walking, yoga, and other low-intensity activities to avoid exacerbating pelvic congestion with vigorous exercise. Diet can increase the intake of iron rich foods such as animal liver and duck blood to supplement nutrients lost during menstruation. To control weight, it should be achieved through a balanced diet and regular exercise at other stages of the cycle to avoid disrupting hormone balance. When experiencing severe dysmenorrhea or abnormal menstrual flow, it is advisable to seek medical attention promptly rather than attempting to lose weight on one's own.
