I don't think you need drugs to lose weight … there is a good way. You can lose five to eight pounds in a week. Half a bag of milk, yogurt … a banana (one dose) … mix them and beat them with a soymilk machine for one minute. Then eat instead of dinner ... If you are eager to lose weight, replace three meals. If you are not in a hurry, take the place of brunch … eat a small amount of rice and light dishes at noon ~ five minutes full. In addition, with exercise, you will soon succeed ... This method is especially useful for loin meat. I hope you lose weight successfully.
