Set yourself up to lose excess belly fat by setting realistic goals. You won't be able to lose fat exclusively from your belly -- it will come from all over your body, including your midsection -- or shed 20 pounds in just a week. You can, however, lose 1 to 2 pounds of fat to start slimming your midsection, using sustainable methods that'll allow for larger weight loss over longer periods of time.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
