Belly fat is nothing to joke about.
"A big waistline puts you at increased risk for many health problems -- diabetes, heart disease, high blood pressure, and stroke,".

Even skinny people can have unhealthy "hidden" belly fat.
Research shows that fat may be folded deep inside the belly around the stomach organs, visible only by CT or MRI imaging. This fat puts people at the same health risks as someone with more obvious big girth, researchers say.

Belly fat doesn't just lay idle at your beltline. Researchers describe it as an active "organ" in your body -- one that churns out hormones and inflammatory substances.
"Abdominal fat is thought to break down easily into fatty acids, which flow directly into the liver and into muscle,"
When these excess fatty acids drain into the liver, they trigger a chain reaction of changes -- increasing the production of LDL 'bad' cholesterol and triglycerides. During this time insulin can also become less effective in controlling blood sugar, so insulin resistance sets in.
Blood sugars start to get out of balance. Fats and clots get into the bloodstream, and that sets the stage for diabetes, heart disease, and more.
And research shows that abdominal fat triggers a change in angiotensin, a hormone that controls blood vessel constriction -- increasing the risk of high blood pressure, stroke, and heart attack.
A study on belly fat presented at the European Society of Cardiology Congress confirms that visceral fat – the type that gathers around your internal organs – is far more dangerous to your health than you might think.
A STUDY ON ABDOMINAL FAT
A study on belly fat presented at the European Society of Cardiology Congress confirms that visceral fat – the type that gathers around your internal organs – is far more dangerous to your health than you might think.
The traditional index of obesity, BMI (body mass index), has been proven to be terribly flawed as having a normal overall BMI and high abdominal obesity was found to be more dangerous than having a total BMI in the obese range.
For example, cardiovascular deaths in the study were 2.75 times higher for those of normal weight who had big bellies compared to those with both a normal BMI and a normal waist-to-hip ratio. It also implies that monitoring one's belly fat is more important than watching BMI.
According to Medical News Today:
"Francisco Lopez-Jimenez, M.D., senior author and a cardiologist at Mayo Clinic in Rochestor, explained: 'We knew from previous research that central obesity is bad, but what is new in this research is that the distribution of the fat is very important even in people with a normal weight.This group has the highest death rate, even higher than those who are considered obese based on body mass index. From a public health perspective, this is a significant finding.'...Dr. Lopez-Jimenez wants readers to understand that even though their body mass index might be normal, it doesn't mean they have a low risk of heart disease. People can determine their risks by getting a waist-to-hip measurement, because where fat is distributed on the body can tell a lot, even if people have normal body weights."
BELLY FAT IN MEN
The trouble with belly fat is that it's not limited to the extra layer of padding located just below the skin (subcutaneous fat). It also includes visceral fat — which lies deep inside your abdomen, surrounding your internal organs.
Regardless of your overall weight, having a large amount of belly fat increases your risk of:
- Cardiovascular disease
- Type 2 diabetes
- Colorectal cancer
- Sleep apnea
DOES AGE OR GENETICS PLAY A ROLE
Your weight is largely determined by how you balance the calories you eat with the energy you burn. If you eat too much and exercise too little, you're likely to pack on excess pounds — including belly fat.
However, aging plays a role. As you age, you lose muscle — especially if you're not physically active. Loss of muscle mass decreases the rate at which your body uses calories, which can make it more challenging to maintain a healthy weight. In addition, in some men fat cells in the arms and legs lose the ability to store fat, which causes any excess fat to go to the abdomen.
Your genes also can affect your chances of being overweight or obese, as well as play a role in where you store fat.
Can you really get a beer belly from drinking?
Drinking excess alcohol can cause you to gain belly fat — the "beer belly." However, beer alone isn't to blame. Drinking too much alcohol of any kind can increase belly fat, although some research suggests wine might be an exception.
If you drink alcohol, do so only in moderation. The less you drink, the fewer calories you'll consume and the less likely you'll be to gain belly fat.
For men, a waist measurement of more than 40 inches (102 centimeters) indicates an unhealthy concentration of belly fat and a greater risk of health problems.
BELLY FAT IN WOMEN
This is likely due to a decreasing level of estrogen, which appears to influence where fat is distributed in the body.
For women, an expanding waistline is sometimes considered the price of getting older. For women, this can be especially true after menopause, when body fat tends to shift to the abdomen.
However, aging also plays a role. Muscle mass typically diminishes with age, while fat increases. Loss of muscle mass also decreases the rate at which your body uses calories, which can make it more challenging to maintain a healthy weight.
Many women also notice an increase in belly fat as they get older — even if they aren't gaining weight. measurement of 35 inches (89 centimeters) or more indicates an unhealthy concentration of belly fat and a greater risk of problems such as heart disease, high blood pressure and type 2 diabetes.
MEASURING BELLY/ ABDOMINAL FAT
The University of Maryland offers a handy online waist-to-hip ratio calculator you can use, which also tells you whether or not you might be at an increased risk for heart disease. The featured study used the following waist-to-hip ratio designations:
- Normal = 0.85 or below in women, and 0.90 or below in men
- High = 0.85 or greater in women, and 0.90 or greater in men
Another even simpler method to figure out if you have a weight problem is to measure only your waist circumference (the distance around the smallest area below the rib cage and above your belly button). Waist circumference is the easiest anthropometric measure of total body fat.
Either of these methods are far better than BMI for judging disease risk, as BMI fails to factor in how muscular you are. BMI also cannot give you an indication of your intra-abdominal fat mass.
Waist size, on the other hand, gives a good indication of the amount of fat you're carrying, particularly around the stomach area. Abdominal fat is considered an important risk factor for cardiovascular diseases such as coronary heart disease and stroke. Your waist size is also a powerful indicator of insulin sensitivity, as studies clearly show that measuring your waist size is one of the most powerful ways to predict your risk for diabetes. If you're not sure if you have a healthy waist circumference, a general guide is:
- For men, between 37 and 40 inches is overweight and more than 40 inches is obese
- For women, between 31.5 and 34.6 inches is overweight, and more than 34.6 inches is obese
LOSING SOME FAT
You can tone abdominal muscles with crunches or other targeted abdominal exercises, but just doing these exercises won't get rid of belly fat. However, visceral fat does respond to the same diet and exercise strategies that can help you shed excess pounds and lower your total body fat. To battle the bulge:
- Eat a healthy diet. Emphasize plant-based foods, such as fruits, vegetables and whole grains, and choose lean sources of protein and low-fat dairy products. Limit saturated fat, found in meat and high-fat dairy products, such as cheese and butter. Choose moderate amounts of monounsaturated and polyunsaturated fats — found in fish, nuts and certain vegetable oils — instead.
- Keep portion sizes in check. Even when you're making healthy choices, calories add up. At home, slim down your portion sizes. In restaurants, share meals — or eat half your meal and take the rest home for another day.
- Include physical activity in your daily routine. For most healthy adults, the Department of Health and Human Services recommends moderate aerobic activity, such as brisk walking, for at least 150 minutes a week or vigorous aerobic activity, such as jogging, for at least 75 minutes a week. In addition, strength training exercises are recommended at least twice a week. If you want to lose weight or meet specific fitness goals, you might need to exercise more.
To lose excess fat and keep it from coming back, aim for slow and steady weight loss — up to 2 pounds (1 kilogram) a week.
