How can i thin my stomach it is very fat?

Exercise: It is difficult to lose weight in spots but exercising aerobically at least 4 times a week for 40 minutes or more in addtion to an excellent diet will help. Stomach fat is directly related to diet, stick to a plant based diet similiar to the mediterranean diet. Best wishes.

Abdominal fat.: For a flat abdomen 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 (i.e., running, swimming, nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.).
