Hello, women should never lose weight during menstruation. First, it didn't work. Second, it is very harmful to health. In fact, try not to eat or drink after 5 pm, and the weight loss effect will be obvious. Combined with doing some hula hoop and other sports, the effect will be better. It's best to eat some soy products, which will make the skin relax due to weight loss. It's best not to eat too much of those diet pills. They should be bad for your health.
