Exercise Better Than Dieting for Belly Fat Loss

/

Belly fat is something many of us struggle with, especially after pregnancy and going into menopause. The fat stored during pregnancy and the change in estrogen is responsible for fat distribution to your abdomen. And while watching what you eat is essential, a recent research review shows exercise may be even more effective for specifically targeting visceral fat. Visceral fat is the fat that wraps around organs deep in your abdomen. This type of fat increases your risks for things like heart disease and diabetes. So losing it is good for your health.

In a recent research review, researchers compared how well exercise versus cutting calories reduced visceral fat in people with overweight or obesity. Researchers looked at data from 40 different studies with over 2,190 participants. Some people dieted, some exercised, and some did neither. Everyone who dieted or exercised lost visceral fat. The results showed that ONLY the exercise groups showed a dose response, where increasing exercise meant more visceral fat loss. Cutting calories did reduce visceral fat, but diet didn’t show the same dose effect. Eating fewer calories didn’t necessarily equal more fat loss. So in this case, more exercise was better than further calorie restriction.

Exercise causes fat loss via an increase in energy expenditure, while caloric restriction results in fat loss via a decrease in energy intake. Researchers theorize the results can be attributed to exercise preserving muscle while dieting alone possibly causing muscle (lean mass) loss. More muscle means you’re burning more calories at rest, so you definitely don’t want to lose muscle while attempting to rid the postpartum belly fat.

Why This Matters for Moms

Early postpartum before you’re able to do vigorous exercise, nutrition and calorie reduction might be your best tool for losing some of the stored abdominal fat from pregnancy. But, be sure to keep in mind:

  • adequate protein is important to prevent muscle loss (mom butt)

  • there are increased calorie requirements while breastfeeding, and the energy and nutrients needed for tissue healing come from a healthy diet

When you’re able to safely return to physical activity, exercise will be an important part of your fat loss plan. Rather than continuing to cut calories, you’ll increase your exercise.

Another perspective is that yes, your body does need to accumulate fat during pregnancy, but maintaining a healthy weight and not gaining excess visceral fat is also important. So more points for prenatal exercise during pregnancy!

The Takeaway

If your mommy pooch concerns you, focus on both your diet and physical activity. To better your chances of losing the fat around your abdomen, make sure that exercise is a part of your program. If the researchers’ theory is correct and losing muscle mass is responsible for the dose-effect difference between diet and exercise, make sure strength training is the foundation of your fitness program. Lastly, keep in mind that this research review was conducted on overweight and obese individuals, but did not specify if any of the participants were early postpartum or approaching menopause.
