Why is the period a golden period for weight loss after menstruation

Patient's question:

No

Doctor's answer:

During the menstrual period, the human body consumes twice as much energy from sugar as usual, so even if you eat a little sweet food in the first three days of your period, you won't gain weight. Starting from the fourth day, progesterone levels are at their highest, and metabolism accelerates. Therefore, starting from the fourth day, exercising can be twice as effective in weight loss compared to usual.
