Why is it so hard to lose fat in my butt?

Genetics dictates where your body burns fat.  For example, you may desire to lose weight in your hips and buttocks, but very often, the place you most want to lose it is the last place it burns. This is known as spot reducing and it doesn’t work. You cannot burn fat in one particular area on your body. While it's true that you can build muscle in different locations of your body such as your legs and buttocks based on what strength-training exercises you do, there's no way to "spot reduce" fat.  Lastly, women tend to carry more fat in their lower body and buttocks to aid in child-bearing.

If you're having trouble trimming your tush, a slow metabolism may be to blame, says integrative medicine specialist Dr. Mark Liponis. To learn how to speed it up and lose fat from your butt, watch this video.
