No, tummy tuck is not considered an effective way to lose weight. You should not have tummy tuck if your goal is to lose weight. For best results, you should be close to your ideal weight before surgery. Tummy tuck may remove a few pounds of excess skin and fat but the amount is negligible. Keeping that in mind, some tummy tuck patients do lose weight after surgery because they are inspired and motivated by their results to eat right and exercise regularly.
