Chromium stabilises the blood sugar, and prevents binging on carbohydrates, if that's of any help to you. Green tea extract should be good for everything, including metabolism.
You can also get different plant fibers (all natural) in capsules as well. You take them 1 hour before your main meals, and drink a lot of water with it. The plant fibers in the capsule will expand as they suck up all the water you drink, and at the same time make you feel full longer as they are slower digested. I've actually tried ones, and I think they work pretty well. I end up feeling really full at one serving, even though I would usually be able to go for at least 2. After I stopped taking them, I was kind of a habit, only eating one serving instead of 2 or 3. So in that sense, I felt like it worked.
