My friend split up with his girlfriend a couple of years ago, and he put on loads of weight. He says its not to do with her but has admitted that he is depressed now, because of the weight and that he hasnt had a girlfriend since. I feel that the relationship ending is the sole reason he has let himself go, but he gets upset every time i try to talk about it. He has put 10 stone on in two years and I am panicking and very upset about his health as he refuses to get any medical help and insists that the fad diets he is going on will suffice. What do I do?
