Some people speculate that storage of fat specifically in that region of the body might be related to cortisol, a stress-released steroid that affects carbohydrate and fat metabolism. So, if you lead a chronically stressful life, you may be releasing excess cortisol and storing excess fat in that region of your body.
There are a few supplements you can take to target that area, if that's your thing (and something far, far, far, far safer than going under the knife). Here would be my recommendations:
Relora - Relora is an all-natural stress relief formula based off the Magnolia officinalis and Phellodendron amurense herbs. It's non-addictive, no significant side effects. It has been linked to helping eliminate fat from that region of your body, as well as reduce the effects of stress-related eating.
Amino Sculpt - This is a collagen supplement that acts as a cortisol inhibitor. It helps you burn calories, is completely nonstimulant, and since it is a cortisol inhibitor, it targets your spare-tire. You take it at night before bed, and it works while you sleep.
