Carrying a few extra pounds isn't uncommon, especially as people get older. But those pounds can lead to serious health risks. That's particularly true if the weight is in the form of belly fat.

How much a person weighs depends in large part on four things:

• Calories taken in each day.
• Calories burned off each day.
• Age.
• Genetics.

People who regularly eat and drink more calories than they burn each day are more likely to gain extra weight, including belly fat.

Getting older also makes a difference. People lose muscle as they age. And the problem is worse for those who are not physically active. Loss of muscle mass decreases how quickly the body uses calories. That can make it more challenging to maintain a healthy weight. For example, when men are in their 50s, they need about 200 fewer calories a day than they do when they are in their 30s.

Genes can contribute to an individual's chances of being overweight or obese too. It also plays a role in where the body stores fat.

Drinking alcohol can lead to what's sometimes called a beer belly, but beer alone isn't to blame. Drinking too much alcohol of any kind can add to the problem. If you drink alcohol, do so only in moderation. For men, that means up to two drinks a day. The less a person drinks, the fewer calories, and the less likely belly fat will build up over time.

To see if your belly fat is a concern, measure your waist:

• Stand and place a tape measure around your bare stomach, just above your hipbone.
• Pull the tape measure until it fits snugly, but it doesn't push into the skin. Make sure the tape measure is level all the way around.
• Relax, exhale and measure your waist. Don't suck in your stomach as you measure.

For men, a waist measurement of more than 40 inches (102 centimeters) signals an unhealthy amount of belly fat and a higher risk of health problems. In general, though, the greater the waist measurement, the higher the health risks.

You can strengthen and tone abdominal muscles with crunches or other exercises focused on your belly. But doing those exercises alone won't get rid of belly fat. The good news is that visceral fat responds to the same diet and exercise strategies that can help get rid of other extra pounds and lower total body fat. Try these tips:

• Eat a healthy diet. A healthy diet involves:
• Focusing on plant-based foods, such as fruits, vegetables and whole grains.
• Choosing lean sources of protein, such as fish and low-fat dairy products.
• Limiting processed meats, as well as the saturated fat that's found in meat and high-fat dairy products, such as cheese and butter.
• Choosing moderate amounts of monounsaturated and polyunsaturated fats. They are found in fish, nuts and certain vegetable oils.
• Choose portion sizes wisely. Even when you're making healthy choices, calories add up. At home, cut down your portion sizes. In restaurants, share meals. Or eat half a meal and take the rest home.
• Replace sugary drinks. Drink water or other beverages without sugar instead.
• Get active. 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. 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. There is some evidence that high-intensity interval training (HIIT) can help reduce belly fat, as can strength training.

Losing belly fat takes effort and patience. To lose extra fat and keep it from coming back, aim for slow and steady weight loss. Ask your health care provider for help getting started and staying on track.
