You used to lose weight on an extreme diet. This method not only can't have a good effect, but also rebounds quickly in the later period. The most important thing is that it has great side effects on your body. You don't come during menstruation because you don't have enough calories in your body. If you eat too much, your body's calories can't keep up, which leads to menstrual disorders. Don't worry, you must pay attention to health and effectiveness when choosing weight loss methods in the future.
