My waist is 32' what can i do to reduce it ...

Spot fat loss does: not occur naturally. By losing weight in general some will probably be waiste fat. But, we don't get to choose what area of body fat is lost from. Eat healthy & be physically active. Calories burned must > those consumed. Engage in regular aerobic exercise (i.e. running, swimming, Nordic track, bicycling, kickboxing, walking, cross country skiing, hiking, etc.)
