Would a 100cc lipo do any good for a relatively fit person? (Photo)

Thank you for the question and post.  Have you tried Sculpsure or Emsculpt.  These are 2 devices which you did not mention and which can help with stubborn areas of adiposity.  100 cc is a very small volume and it may be difficult to appreciate much difference with this.  Please see a body sculpting expert.  Be well.

Only your surgeon will know what is reasonable for your body with the liposuction that the surgeon usually performs. Liposuction can cause significant swelling. In some cases, this lasts a few months, and your final result will not be visible until then.
