Belly fat — why menopause promotes it and how you can keep it off.
Whether it's because of heredity, hormonal changes or aging-related weight gain, many women notice an increase in belly fat as they grow older — and especially after menopause. Gaining fat in your abdomen is particularly unhealthy when compared to other locations in your body. Excess belly fat increases your risk of cardiovascular disease, diabetes and certain types of cancers. The good news is that a few lifestyle changes and some targeted abdominal exercises can help you battle your belly bulge.
When fat gathers in your abdomen
As you age and your metabolism slows down, the amount of fat in your body slowly increases. Women experience an even greater fat percentage increase than men do. Then after menopause, your body fat distribution tends to shift — less in your arms, legs and hips, and more in your abdomen.
You may think belly fat is limited to the stuff out front that you can grab with your hand — but it's the fat you can't see that's really a cause for concern. Visceral fat lies deeper inside the abdomen, surrounding the abdominal organs. Gaining this type of fat has been linked to cardiovascular disease, diabetes and other health problems. Subcutaneous fat, located between the skin and the abdominal wall, is more visible but also less likely to be a health risk.
While a slowing metabolism and decreased physical activity contribute to overall weight gain as you age, those factors don't influence visceral fat accumulation directly. Heredity may be the culprit — you may simply have inherited a tendency to gain weight in your midsection. Hormones also play a role. Hormonal changes after menopause may change the way that your body breaks down and stores fat, leading to more fat accumulating in your belly.
Some women even experience a widening waist without gaining any weight. Although you may not be gaining extra fat, your abdominal fat is increasing as limb and hip fat decreases. Even in women of a normal weight, too much fat concentrated in the midsection is unhealthy.
Measuring your middle
You know you've gained some inches around your torso, but how can you know whether it's an unhealthy amount? You can calculate your body-mass index (BMI) or waist-hip ratio, but researchers have found that simply measuring your waist can tell you whether you have an unhealthy amount of belly fat. In fact, BMI may not be an accurate measure of body fat percentage or fat distribution, particularly after menopause.
To measure your waist, run a tape measure around your midsection at about the level of your navel. Breathe normally, don't hold your tummy in, and don't pull the tape so tight that it presses your skin down. In a woman of healthy weight, a waist measurement of 35 inches or more indicates an unhealthy concentration of abdominal fat. Some research has shown that a measurement of 33 inches or more, no matter what your weight, increases your health risks.
