A tummy tuck or liposuction is for body contouring not weight loss. However, liposuction can be performed in a number of areas:abdomen, flanks, hips, thighs, buttocks, back, knees, neck, arms, and calves, while a tummy tuck is for the abdomen/flanks only. The maximum amount of fat that can be safely removed in one procedure is 4-5 liters or 8.8 - 11 lbs of localized fat. To lost that much localized fat, you would most likely have to lose 20-25 lbs on a diet and exercise program.The cost of liposuction depends on the number of areas and the time necessary to safely perform the procedure. When front and back liposuction is desire, it takes more operative time to prep and drape the areas for the procedure. In my NJ practive, the total cost of three hour (max time) liposuction is $7800, which includes the Board Certified Professional fee, B/C anesthesia fee, and Medicare Approved surgicenter.Best
