Don't forget, some people are genetically predispositioned differently.
What seems easy for you may be all but impossible for me. And vice versa.
An important note: find your metabolic threshold... don't eat nor excersize beyond your "window." Consult your doctor regularly.

doctors will not normally recommend on diet because that is a basic question for them and really how can they say what you should do, not should do because normally nowadays all this information is available on the net for people to access. I am not saying, if your doctor feels there is a real problem, they will not recommend, but it is a general question and I would not even bother my doctor with this sort of issue unless I thought for sure it was effecting my health and she knew that.

What you should do is for a couple of days actually keep track of what you eat, and if your actually exercise, and then analyzise what your doing and then reinvent your eating habits and work in regular exercise. You can be predisposed to alot of things, but when you eat wrong, nothing will help and no excuse will work. It does take work dedication, work and small changes to help your boy look and feel better.
