In this video, we learn how to remove body fat or stretch marks in GIMP. First, go to filters, then distort, then warp. When you are in this window, you will be able to see all the different distortions that you can do. To help you remove the fat, use the "move" tool and a proper sized brush. Now, press on the stomach and slowly press down on it until you see the part of the body start to become smaller. Don't do it too quickly, or the picture will look fake. When finished, save your new picture and enjoy a new look!
