Weight loss might seem complicated because it can be difficult to achieve, but it’s really a matter of using up more calories than you consume. Weight loss through diet and exercise involves shrinking the fat cells, rather than eliminating them.
When you start to lose a few pounds, you might not see a major difference right away. That’s because you lose weight all over your body, rather than in a specific area like under your chin or on your upper arms. It’s not possible to spot reduce, or to lose weight in a specific area.
In contrast, liposuction does target specific areas of body fat. It can reduce the number of fat cells in targeted areas such as the belly, hips, thighs, and arms. (Note, however, that lipo can only remove subcutaneous fat just under the skin, rather than visceral fat that surrounds the organs.) However, it’s still possible for the remaining fat cells to grow bigger. This is why it’s important to continue to eat well and exercise.
