Brian I would like to help you more. Unfortunately i don't as much as people here. But i can tell you a bit of what my nutriologist has recommended me. When i was on prednisone i gained 10 kilos, i think that is like 20 pounds. I went to the nutriologist and she gave a diet. It was helthy food just as the one you tell us you eat. So i guess what could make you lose more weight would be exercise. Swimming is a good one. I don't know if you're able to do it. But if you are i think you should try it. It can burn more calories thatn walking because you use all your muscles. As far as food is concerned, besides eating healthy food, it is a good idea to eat vegetables first. According to my nutriologist it is easier to process food if you start with veggies. Go see a nutriologist if you don’t loose weight soon. He or she will recommend an adequate balanced program for you. Good luck.
