One piece of the puzzle that's necessary to reduce overall body fat (in order to lose belly fat) is to focus on your diet. Jillian said a clean, calorie-controlled diet is important for reducing belly fat, and be careful not to overeat.
Make sure your diet is low in processed sugars and flours. "Don't drink too much alcohol," she advised. "Really try to bring this to four drinks a week, tops." Jillian also said to keep sodium intake down in order to avoid water retention, and make sure to drink plenty of water to help reduce water weight.
