Hello, my friend. I heard that you put some weight. Well, i try to help you, because i was fat many ears ago. I think you  already tried different diet. And that do not work, i guess. You can also count calories, and that will be work. But i want to say something. Some secret  between you and me.There is the reason that people eat to many food. The reason is - problems with life. People seize up their pain. That is all. If you dont have a pain - you dont need eat too much. So, relax, and try to got good without food.
