Discipline is really the key. In China, there is a dietary food like oatmeal, people lost more than 20kg within a week and they feel good. The product is called 159. It's really popular now in China. If you have it for 3 meals a day without eating anything else but tons of water, you will achieve unbelievable result. I don't want to lose weight, my husband and I have been using it to control our weight. The key theory of it is same as what we've know- control your mouth. I am not promoting this product here, but trying to say weight control is all about disciple.
