Create a calorie deficit through your
diet. Eating fewer calories than you use makes your body use the fat storage in your belly to provide energy. The Centers for Disease Control and Prevention recommends a calorie deficit of 500 to 1,000 calories daily for 1 to 2 pounds in weight loss. To lose belly fat fast, aim for at least a calorie reduction of a 1,000 calories daily.
