When it comes to improving your self-image and your body, diet and exercise always factor in. Theres undoubtedly room for improvement in both for most of us, and more often than not, a healthier diet and more exercise will help. Yet, there is such a thing as eating fairly healthy and exercising regularly and still finding that belly impossible to shape. In fact, it is often the case that after you lose weight, excess fat and loose skin stubbornly exist around the belly. In situations like this, a tummy tuck (abdominoplasty) might be the best way to tighten abdominal muscles and reduce the amount of excess skin.
