Feet and Fork Fight Belly Fat

Call it a muffin top, beer belly or middle-aged spread–the fact is, by the time most Americans reach adulthood they’ve added inches to their waistline. And those extra inches put you at a higher risk for coronary artery disease, type 2 diabetes, stroke, high blood pressure and certain types of cancer.

Even if your weight, measured as Body Mass Index (BMI) is normal (18.6 to 24.9), you could still be at a higher risk for disease if your waist circumference is too high. Your lifestyle choices, including diet and exercise, can help you fight belly fat.


There are two different types of fat: subcutaneous fat and visceral abdominal fat, which behave differently metabolically. Subcutaneous fat is distributed throughout the body, including the abdominal area, and as the name suggests, it’s the fat that lies underneath the skin. It’s what wiggles and jiggles when you walk or what you wrestle with as you squeeze into your jeans.

And while having too much isn’t benign, the role it has on adverse health risk factors pales in comparison to the other kind of fat. Visceral fat, also called abdominal fat, is fat that’s deposited inside the abdominal cavity around organs.

High levels of visceral fat are linked to adverse health indicators: high blood triglycerides, low “good” HDL cholesterol, high “bad” LDL cholesterol, increased markers of inflammation, insulin resistance and nonalcoholic fatty liver disease.

A meta-analysis published in the May 2011 issue of the Journal of the American College of Cardiology looked at data from over 15,900 people with coronary artery disease and concluded that those with abdominal obesity–even with a normal BMI–had double the risk of death.

A high waist circumference, especially in women, is also a risk factor for developing type 2 diabetes, according to a recent study of biometric markers in over 300,000 Europeans, published online in MedlinePlus in June 2012.


Unfortunately, the measurements typically taken in the doctor’s office–weight and height, which are used to calculate BMI–are not sensitive enough to determine abdominal fat. People often considered to be at a healthy weight may still have an elevated risk due to abdominal adiposity.

A study published in the May 2012 issue of the International Journal of Obesity compared BMI classifications to body fat percentage. Results showed that 29 percent of people classified as normal weight and 80 percent of people classified as overweight had body fat measures putting them within the obesity range (defined as over 25 percent body fat for men and 35 percent for women).

Another study published in the January 2012 issue of the same journal, which looked at BMI vs. waist circumference as a predictor of health outcomes in 8,064 Canadian adults, concluded that the risk of death from all-causes and specifically cardiovascular disease and cancer was consistently higher among those who had large waist circumferences compared to those with a higher BMI.

BMI does not distinguish between individual variations in body composition and variations due to ethnicity, sex and age. Considering your waist circumference is a much more accurate method of determining your risk for disease.


Increased age, sex (men more than women), menopause, smoking, a high-caloric diet, sedentary behavior and ethnicity (Asians are at increased risk and African Americans are at lower risk) are risk factors associated with increased abdominal fat. However, making and sticking to lifestyle choices that include diet and exercise can lower levels of abdominal fat. Several diet and lifestyle strategies have been linked with reducing abdominal fat.


As little as 150 minutes per week of moderate intensity aerobic activity, such as brisk walking, dancing and stationary cycling, appears to be enough for reducing abdominal fat, concludes a systematic review and meta-analysis of the effects of exercise on abdominal fat published in Obesity Reviews 2012.

While a significant relationship between weight loss and abdominal fat reduction was observed, the benefits of aerobic exercise were seen even without weight loss, and surprisingly, were not dependent upon exercise intensity. Resistance training did not appear to reduce visceral fat. However, it may be effective in preventing abdominal fat in the first place, or its re-accumulation when weight is regained after weight loss.


Weight loss reduces fat mass overall, as well as abdominal fat.
“Research shows that losing as little as 5 to 10 percent of body weight has real health benefits,” says obesity research expert Jean Harvey-Berino, Ph.D., R.D., professor and Chair of the Nutrition Department at the University of Vermont and founder of Vtrim, a research-based behavior modification weight loss program which is funded by the National Institutes of Health at the University of Vermont.

“The key is making the behavioral changes that allow you to maintain the weight loss over time. People gain back about a third of what they lose within the first year, so without making behavioral changes, success may be fleeting,” says Harvey-Berino.


The keys to successful, behavior-based weight loss and weight maintenance programs, such as Vtrim, include:

  1. Setting realistic weight loss goals, such as losing 10 pounds at a time.
  2. Lowering caloric intake to between 1,200 and 1,800 calories per day, depending on your initial height and weight (visit www.win.niddk.nih.gov to determine your calorie needs.)
  3. Learning new eating patterns that you can maintain throughout your life.
  4. Tracking and monitoring your progress with daily food and exercise journaling.
  5. Developing a support network by joining a weight loss program or enlisting a friend or spouse for encouragement.


  1. Eat like a Mediterranean. The Mediterranean eating pattern, which is rich in whole grains, fruits and vegetables; moderate in olive oil, fish and alcohol; and modest in dairy, meats and sweets, has been shown to reduce abdominal obesity.
  2. Limit refined grains. According to Cynthia Sass, M.P.H., M.A., R.D., C.S.S.D., dietitian and co-author of the “Flat Belly Diet,” “Eliminate refined grains, like white rice and pasta, and include a small serving of a 100 percent whole grain at each meal. Published research shows this nutrition upgrade helps reduce belly fat.” Switch from refined grains, such as foods made from refined flours, to whole grains, including wheat, oats, quinoa, barley, amaranth, rye and bulgur.
  3. Include nuts. Eating as little as ¼ ounce of daily tree nuts, such as almonds, pecans, walnuts, pistachios and hazelnuts, has been linked with lower abdominal fat.
  4. Choose more bean-based meals. “Regular bean eaters have smaller waistlines; I recommend trading meat for beans or lentils at least five times per week,” says Sass.
  5. Cut “empty” calories. A high intake of low nutrient-density foods, such as sugary beverages, sweets and snack foods is related to increased central obesity.
  6. Focus on fiber-rich foods. Eating high-fiber foods, such as lentils, artichokes, berries and oat bran is associated with lower abdominal fat.
  7. . Eat dairy foods. Including dairy foods, such as low-fat milk, yogurt and moderate amounts of cheese, is associated with lower central obesity.
  8. Enjoy wine in moderation. Lower central obesity has been observed in women with moderate (one glass per day) wine consumption.
