Aid in weight loss

I'm leaning out everywhere except my stomach. Loosing mostly my butt and boobs :( but stomach is the same exact size
even though I lost over 20lbs. Its all subcutaneous fat and can't seem to even lose a centimeter of it. even with
exercise, eating low calorie and relativly low carb. Looking for advice on any supplements that aid in targeting stubborn fat,
that seem to be effective. I was looking at trying Hydroxycut Harcore Elite (powder form)
