When it comes to belly fat, there's not one specific thing that packs the pounds around your midsection. Fat accumulates at your waistline thanks to a combination of factors, including genetics, stress and sleep habits, but what you eat also plays a major role.
When we talk about belly fat, we mean the hard, visceral fat that lies deep in your abdomen and surrounds your organs. This type of fat is more dangerous than the soft, subcutaneous fat that sits just under your skin. Indeed, too much visceral fat — marked by a waist circumference of 40 inches or more for men and 35 inches or more for women — has been linked to an increased risk for such conditions as heart disease, diabetes and high blood pressure, per Harvard Health Publishing.
The good news is that visceral fat is the first to go when you clean up your diet and start to lose weight. Beyond cutting calories, though, the quality of the food you're eating seems to play a key part in how much visceral fat your body tucks away. Here's what the research says about which foods may lead to belly fat, and which might just help to blast it away.
Foods That May Keep Belly Fat at Bay
Foods High in Fiber
Foods like fruits, vegetables, beans and legumes, nuts and seeds, oats, whole-grain or whole-wheat pasta, whole-grain bread and quinoa could potentially reduce the risk of developing too much visceral fat. These foods are rich in fiber, a non-digestible carbohydrate. A study published April 2015 in The American Journal of Clinical Nutrition found that people who reported consuming more fiber were significantly less likely to have dangerous levels of visceral fat.
There are a lot of benefits to eating a high-fiber diet, per the Mayo Clinic, including: lower cholesterol levels, better blood sugar control, healthy weight maintenance, normalized bowel movements and better bowel health. Eating more fiber has even been linked to living longer.
Unfortunately, only about 5 percent of Americans are getting the recommended amount of the nutrient, according to a paper in the January-February 2017 issue of the American Journal of Lifestyle Medicine, which is 25 grams per day for women and 38 grams for men, per the Dietary Guidelines for Americans.
The Mayo Clinic offers the following tips for increasing your fiber intake:
- Eat a high-fiber breakfast cereal.
- Switch grain products for whole grains and aim for at least 2 grams of fiber per serving.
- Bulk up baked goods by substituting white flour for a whole-grain option.
- Increase fruit and vegetables to meet at least five servings or more per day.
- Include legumes whenever possible
- When snacking, choose fresh fruits and vegetables, nuts and seeds and whole-grain options.
Foods Linked to a Larger Waist
Bacon, sausage and deli meats have rarely been associated with a healthy diet. When it comes to reducing visceral fat and your waistline, though, it may be even more important to cut down on these foods. A large study of nearly 50,000 men and women published August 2011 in PLOS One found that consuming processed meat was associated with a greater BMI and waist circumference.
The good news is that unprocessed meats, including lean cuts of poultry, pork and beef, do not show the same association as processed meats do. So while you don't have to give up meat altogether to reduce belly fat, it would be smart to keep meals with bacon, sausage and deli meats to an occasional treat.
Soft drinks and energy drinks are usually packed full of empty calories with little nutritional value. What's more, research published February 2014 in The American Journal of Clinical Nutrition found that visceral fat tends to increase along with increased soda consumption, so reducing your intake of these beverages is a no-brainer.
Swapping some of these beverages with fruit-infused water, sugar-free options or simply plain water will likely help to reduce belly fat.
According to the Mayo Clinic, drinking excess alcohol can lead to a "beer belly," but the alcohol itself isn't solely to blame. Imbibing too much alcohol of any variety adds extra calories, and those extra calories can contribute to a wider girth.
If you're concerned with the size of your waist, make sure to consume alcohol in moderation, which means up to one drink per day for women and two daily drinks for men.
Fried and Fast Foods
Fast food is a convenient option when you're on-the-go, but too much may wreck havoc on your middle. According to the Harvard T.H. Chan School of Public Health, people who eat more fast food also weigh more, have higher triglycerides and have a larger waist circumference than those who eat less.
Fast food is usually high in saturated fat and salt and low in overall nutrients, like vitamins, minerals and fiber. And while you don't have to swear off fries for life, try to limit fast food to those times when you're in a pinch for a meal or have a specific craving in order to help minimize belly fat.
- Overall, a diet rich in whole grains, fiber, lean meats and vitamins and minerals is the best strategy to reduce your risk of harmful belly fat.
- While there is no way to spot-reduce fat in the abdominal area, making lifestyle changes like eating more nutrient-dense food and moving your body more can help you lose weight and belly fat over time.
