Both Hultin and Kinzly agree that drinking alcohol won't help you reduce belly fat. "We say that alcohol is empty calories for a reason; with 80 to 150 calories per drink, these can add up quickly," Kinzly said. "Excessive alcohol will cause the liver to stop metabolizing fat and carbohydrates in order to get the alcohol metabolized first." This leads to the storage of more fat in your body (and your belly), so limit the wine, beer, and cocktails.
