If you believe that you truly can reach your ideal weight prior to undergoing a tummy tuck, you should definitely do so. This will result in the best chances for an excellent result. I often perform tummy tucks on patients who are still much heavier than their ideal weight, however, with dramatic improvement. If you should weigh 50 pounds less than you do currently, for example, but know from years of experience that you realistically will not reach that ideal weight, then a tummy tuck is still possible. Many of my patients find it much easier to lose weight AFTER undergoing a tummy tuck, decreasing to weights that they never could achieve prior to surgery. To summarize, you should try to achieve your ideal weight prior to a tummy tuck if at all possible; if not, do your BEST to lose what you can, then have your tummy tuck.
