Nature has intended for these areas to be energy storehouses when people weren't assured of easily finding food. These were the reserves that kept them alive until they were able to find food. The fat in these areas has a different metabolism that attempts to maintain it as long as possible. As you diet and lose fat in other parts of the body, these areas seem even more out of proportion. There is no exercise that can spot reduce these areas.
Liposuction is the only true spot reducer.
By introducing a thin cannula beneath the surface of the skin, the fat in these troublesome areas can be sculpted to attain the ideal contours. The excess fat cells are permanently removed. The body has formed all its fat cells by the time you reach puberty. After that, if you lose or gain weight, the existing fat cells become larger or smaller. Once the cells are removed, you will no longer accumulate fat in those areas.
