I have a fat belly. is it possible to lose it completely? what can i do?

Start losing weight: It depends where your belly fat is: under the skin or inside the belly. If you have a large belly, it is likely that you have fat in both areas and you need to lose weight. If it is a localized fat in the upper or lower belly or hips, liposuction can help.

There is no such : Thing as spot fat loss. You need to lose weight in general & a certain % will be abdominal fat. Eat healthfully & be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge & “bicycling” exercise on your back. Engage in regular aerobic exercise.
