Melissa McCarthy Weight Loss : Melissa McCarthy has gone from fat to fit. The Oscar nominee though is not letting people know how she did it. The only thing that she has said is that she did not worry about losing weight and that could be one of the reasons for her weight loss. Also she feels that she will again gain weight and probably lose it again. She feels that weight loss should not be the only thing to live for, there are many other things that women can do rather than thinking of just how they look.
