Belly Fat, abflab, spare tire, pot belly, love handles – all these playful phrases refer to what the medical profession calls abdominal obesity. Unfortunately, abdominal obesity is anything but funny. It’s downright dangerous. Research has shown that in young and older people alike, those with big bellies are at increased risk for chronic diseases, such as cardiovascular disease. hypertension. stroke, insulin resistance. diabetes, and even cancer.
More than one-third of U.S. adults – that’s more than 72 million people – are obese, and more than half of all U.S. adults have abdominal obesity, says the Centers for Disease Control and Prevention. Yet you can reduce your mid-section, and your blood pressure and high cholesterol, with a few simple lifestyle changes.
Scientists used to think that fat cells were just a repository for excess fat, like storage trunks that just sit there. But in recent years, researchers have discovered that fat cells secrete hormones and other substances, some bad and some good. Some of these substances help reduce inflammation while some increase inflammation. The more excess fat you have, though, the more bad chemicals the fat produces. Fat cells are active little endocrine factories producing a wide array of hormones and other compounds that arc poured into the blood.
When it comes to belly fat, there are two kinds: subcutaneous fat, which accumulates around your middle, and visceral fat, hidden under your abdominal muscles. Subcutaneous fat contributes to inflammation and cardiovascular disease. Visceral fat plays an important role in our immune system. Visceral fat is filled with white blood cells that mop up microbes and other toxic substances that may escape through the intestinal wall. But too much visceral fat secretes inflammatory chemicals – much more than fat cells found in other parts of your body. Inflammation is what researchers believe leads to chronic diseases, such as heart disease, type 2 diabetes, and cancer.
Excessive visceral fat also dumps a lot of free fatty acids into the bloodstream, which carries them directly to the liver. Chronic overflow of fat to the liver results in high cholesterol, high triglycerides, and insulin resistance. Also, excess visceral fat has been linked to fat accumulating around organs such as the heart and liver, which impairs their ability to function well.
The dangers of belly fat:
• Abflab in midlife increases the risk for dementia and cognitive decline later in life, A 2008 study in the journal Neurology found that central obesity in mid-life triples the risk of dementia 30 years later. Scientists aren’t exactly sure why.
• Researchers in the United States and Netherlands found that women and men with a large waist circumference had a 50 percent increased risk of mortality compared with people with smaller waist sizes, irrespective of their overall weight.
• Data from the 15 year-long Women’s Health Initiative found that the bigger a woman’s waist, the greater the risk for lung cancer in current and former smokers. Researchers suspect that abdominal obesity may affect how the body metabolizes tobacco carcinogens.
• Too much belly fat puts you at risk for metabolic syndrome, which is associated with heart disease and type 2 diabetes.
• Abdominal obesity has been associated with migraine headaches. A study presented by the American Academy of Neurology found that women with extra belly fat were 30 percent more likely to experience migraines than women without excess belly fat.
• Abdominal obesity is a potent risk factor for stroke.
There ls a high range of waist circumference for any given BMI. Some people carry their weight in their thighs or buttocks and have a reasonable waist size. But if their BMI is over 25, they are considered obese and are vulnerable to all the health dangers of obesity. Then again, other people may have a BMI under 25 but a large waist circumference, which categorizes them as being abdominal obese. However, the measurement of girth is a very good predictor of hazard, and the guy who keeps his 35-inch belt but wears it lower and lower so that eventually his belly is hanging over it is not doing himself any favors. To find out if your belly is putting you at risk, you need to know your waist circumference and body mass index (BMI). Together, waist circumference and BMI can be very helpful in assessing your health risks.
Checking your waist circumference is as easy as taking out a tape measure and wrapping it around your waist (but don’t cheat by sucking in your gut when you take the measurement). Men in the United States should have a waist measurement of 40 inches or less, and women should have a waist that measures 35 inches or less. To find yours, wrap a tape measure around your stomach. The bottom of the tape should be even with the top of your hip bone. Keep the tape straight and snug, but don’t let it dig into your skin.
As we age, muscle mass declines. metabolism slows. and fat tends to collect around our middles. But, you can minimize the effects with a healthful diet and regular exercise, If you are conscientious you will see results in several months. Fancy fat-burninq diets or foods that are said to burn fat are a bunch of baloney. No single food Will burn fat. The only way to burn fat is to eat fewer calories and exercise on a daily basis.
Only 26 percent of U.S. adults say they engage in vigorous leisure-time physical activity three or more times per week (defined as periods of vigorous physical activity lasting 10 minutes or more). Abdominal exercises. such as sit-lips. arc a great way to strengthen your abdominal muscles. but they don’t do a thing to get rid of the fat on top or underneath them. Daily cardiovascular exercise. such as brisk walking. biking. or taking an aerobics class. helps burn belly fat.
Your genes influence where your body decides to store extra fat. Even if you are genetically inclined to store fat around your waist, you are not doomed to end up looking like your rotund Aunt Ida. Research and common sense tell us that behaviors such as smoking, drinking alcohol, and being a couch potato lead to less healthy lifestyles, which often lead to a big stomach.
If you manage your caloric intake and engage in daily exercise, you will still have Aunt Ida’s blue eyes-but not her waist. When your body is stressed. it produces cortisol, a hormone that places your body on alert. Research suggests that this hormone can lead to an increase in belly fat in adults and children. Stress is also linked to behaviors such as increased eating, drinking, smoking, and less exercise.
Men have roughly double the amount of abdominal fat as women. So it is not unusual to see men with big bellies. But once a woman enters menopause, the playing field levels. Hormonal changes that occur in a woman’s body may change the way she stores fat. Menopause is associated with selective deposition of visceral fat as well as other metabolic changes that increase women’s risk for heart disease. Women ages 45-54 are three times more likely than men that age to have a stroke, and belly fat appears to be the reason why. It raises cholesterol and blood pressure.
No matter your age, you need not be stuck with a big gut for the rest of your life. A 2003 study in the Journal of/he American Medical Association found that post-menopausal women who engaged in 45 minutes of exercise daily, such as brisk walking, lost between 3.4 percent and 6.9 percent of their abdominal fat in a year’s time.
Walking the equivalent of 11 miles a week prevented accumulation of visceral fat. More exercise resulted in a loss of ab flab. Subjects who did not exercise gained a significant amount of abdominal fat, including visceral fat in only six months. There is a high cost of a sedentary lifestyle in the short and long-term. The good news is – when people lose weight, often the first place they lose it is in their midsection.
Beware the quick fix. If you are overweight or obese. you need to lose some weight for the sake of your health and well-being. Stay away from fad diets. including those that suggest cutting out entire food groups such as carbohydrate. and from quick fixes. such as pills and certain juices that promise rapid weight loss. The best overall approach to reducing belly fat is to combine sensible eating with regular exercise.
Healthful foods include whole grains, beans, low-fat or non-fat dairy, and lots of vegetables and fruits. Eating lean protein, such as fish and chicken is associated with a reduction in abdominal fat. Reducing the amount of saturated fat – the kind found in butter, cheese. meat, and ice cream – also helps reduce belly fat and your risk of cardiovascular disease.
