What's a good way to fight belly fat?

Diet & Exercise: The best way to lose fat is to lose weight. The best way to lose weight is to exercise regularly and maintain a healthy diet. There is no way to selectively 'lose weight' from one body part, unless you choose cosmetic surgery or body sculpting procedures. You can tone your abs, but this alone will not help you lose belly fat.

There's no such: Thing as natural spot fat loss. You need to lose weight in general & a certain % will be abdominal fat. Eat healthfully & be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge & “bicycling” exercise on your back. Engage in regular aerobic exercise.
