Excessive eating during menstruation can lead to weight gain if it results in daily intake being greater than daily consumption.
Most research evidence suggests that a woman’s basal metabolic rate does not change significantly during menstruation and is comparable to that during non-menstrual periods. Therefore, if one eats too much during menstruation, resulting in daily intake exceeding daily consumption, the excess intake will be converted into fat accumulation, resulting in weight gain.
There is generally no special difference in metabolism between menstruation and non-menstruation periods, and excessive intake can lead to weight gain as well. It is recommended to adopt a balanced diet and regular exercise habit, and consume a variety of foods such as fruits and vegetables, high-quality proteins and coarse grains in moderation to maintain a healthy body weight.
