Is no weight loss after 7 liters of fat removal through liposuction normal?

You will likely only lose a few pounds from the liposuction procedures. You will experience bloating and fluid build-up following the procedure.  The purpose of liposuction is to remove the fat from problem areas in your body, thereby contouring your physique for a more pleasing physique.  As the swelling resolves, the fluid is replaced by fat in the non-lipo areas.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA 

Generally, liposuction does not really have a significant effect on the overall body weight, this is because liposuction removes excess fats from a specific body part and would therefore be of little influence to the over all weight of the patient. Liposuction contours the body, it does not significantly decrease weight.
