If you are trying to survive on shakes that is the root of your problem. Solid food will give you more mass in your stomach than shakes. For example, for breakfast, I eat 2 boiled eggs and 3 slices of turkey bacon. For lunch, I each grilled chicken tenderloins and a vegetable. For dinner, I have grilled fish and a vegetable. If I am hungry in between, I will have yogurt or string cheese. I am not hungry most of the time but I do have an issue with being greedy which is another story. From one sister to another, focus on filling with solid food.
