A tummy tuck is not a shortcut to achieve a flat, toned stomach. It takes exercise and a healthy diet to even get to the point where a tummy tuck can be effective. But no matter how many sit-ups you do, and no matter how careful you are with your diet, sometimes you just can’t get your stomach as flat as you hope it would be. Fortunately, cosmetic surgery can be a solution. A tummy tuck can finish off that last little bit of unwanted skin and fat to achieve a flat, toned stomach.
