Aerobic exercise bests resistance training at burning belly fat

Aerobic exercise is your best bet when it comes to losing that dreaded belly fat, a new study finds. When Duke University Medical Center researchers conducted a head-to-head comparison of aerobic exercise, resistance training, and a combination of the two, they found aerobic exercise to be the most efficient and most effective way to lose the belly fat that's most damaging to your health. This isn't the fat that lies just under your skin and causes the dreaded muffin top. Belly or abdominal fat – known in scientific communities as visceral fat and liver fat - is located deep within the abdominal cavity and fills the spaces between internal organs. It's been associated with increased risk for heart disease, diabetes, and certain kinds of cancer. "When it comes to increased health risks, where fat is deposited in the body is more important than how much fat you have," says Duke exercise physiologist Cris Slentz, Ph.D., lead author of the study published in the American Journal of Physiology. "Our study sought to identify the most effective form of exercise to get rid of that unhealthy fat." The Duke study showed aerobic training significantly reduced visceral fat and liver fat, the culprit in nonalcoholic fatty liver disease. Aerobic exercise also did a better job than resistance training at improving fasting insulin resistance, and reducing liver enzymes and fasting triglyceride levels. All are known risk factors for diabetes and heart disease. Resistance training achieved no significant reductions in visceral fat, liver fat, liver enzyme levels or improvements in insulin resistance. The combination of aerobic with resistance training achieved results similar to aerobic training alone. "Resistance training is great for improving strength and increasing lean body mass," says Slentz. "But if you are overweight, which two thirds of the population is, and you want to lose belly fat, aerobic exercise is the better choice because it burns more calories." Aerobic training burned 67% more calories in the study when compared to resistance training
