There is no reward, such an effective method is cheap for you. Cassia seed is soaked in water and only eats breakfast every day (no more than 200g, mainly carbohydrates, supplemented by a small amount of food from protein). After that, don't eat all day. If you are hungry, drink a cup of honey and soak in water. Only last for one week, and lose more than 5- 10KG per week (don't overeat or rebound).
