My stomach has been able to handle less food?

Not surprising since you have started to burn the fat, alot is also psychological, not in a bad way. Butif you have decided to get and stay fit your body will respond. If, to get in shape, you decided you needed to lose weight then psychologically your body is responding.. Muscles require food to keep strong, but what happens depends on the type of food. Keep carbs, soda and fast food out of your diet. Foods high in fat will make you feel full and you will start to lose muscle.
