Drink a bowl of porridge or a bag of skim milk in the morning, eat some bread, eat a small bowl of wonton at noon and drink water in the afternoon. You can't eat anything. Afternoon is the most important thing. Even if you want to eat, you should eat before 4 o'clock. Remember that it's 4 o'clock. As long as you follow my method, you can see the effect in a week. Once it works, stick to it.
