The only advise is a protien diet and exercise, though it doesn't seem to help me all that much. But I have fibromyalgia and with that comes belly fat. I know that it is hard to do these things when you are depressed. So I try to turn on some music and dance when I am alone. It has an aerobic affect and it makes me feel good. But I am constantly fighting weight gain also. I have heard topomax can help you lose weight.
Try not to beat yourself up when you gain a few pounds, I think it only adds to the depression. Also go by your clothes fit you and not by the scales. A lot of times the weight is muscle and not body fat. Muscle weighs four times more than body fat. Most of all, don't give up. And try not to get discouraged. Drink a lot of water too. That is suppose to be very healthy.
Good luck to you
