No matter how many ab workouts you do, they won't help you reduce belly fat. Instead of focusing on spot reduction — targeting one specific area on your body — you've got to train your entire body, fuel up with nutritious foods, and make sure that you're recovering (nope, all-nighters won't help) to lose fat in general. And losing body fat all over means you will be losing some on your belly as well.
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
