As per observation ,it is found that the fat people are habitual to eat food with great speed.And just opposite to these it is found that the thin people are very slow during eating their food.I had two friends with same properties i.e the fat one eats fast and the thin guy eats slowly.I just told them to change their eating habits.Then the stout started eating slow and the other one started eating fast.The effect that resulted was unbelievable,I worked with great result which helped the stout one to reduce weight and the other one to increase the weight.I don't know how it affected internally but it worked.
