Our Metabolism Changes as We Get Older…
Can You Avoid Middle-Age Spread?
As you age, you may notice you have less muscle and energy and more fat. Carrying those extra pounds may be harming your health. It’s easy to be confused by advice about diet and exercise, but they’re key to avoiding weight gain as you get older. As you move through your 30s, 40s, 50s, and beyond, you can take steps to help fight the flab that can come with age.
Your metabolism changes as you get older. You burn fewer calories and break down foods differently. You also lose lean muscle. Unless you exercise more and adjust your diet, the pounds can add up. Middle-age spread can quickly become middle-age sprawl.
“At some point, everyone loses muscle mass as they get older and gains abdominal fat,” says National Institute of Health’s (NIH) Dr. Mark Mattson, an expert on aging and exercise. The so-called couch-potato lifestyle is the main culprit behind middle-age spread. “Over-eating and leading a sedentary lifestyle can speed up age-related changes in metabolism,” Mattson says.
Metabolism – Chemical changes in the body that create the energy and substances you need to grow, move, and stay healthy.
Sedentary – Sitting or lying down while you’re awake.
Key Culprit: Leptin
One key player in age-related changes is a chemical called leptin, which helps your brain tell you to stop eating. Leptin signals don’t work as well as you get older, so you might continue to feel hungry even after you’ve eaten. Obesity makes leptin even less effective.

“There’s a reward part to everything you eat,” says Dr. Josephine M. Egan, an NIH expert on diabetes and aging. “You get the taste of the food. You feel good. Normal-weight people will satisfy cravings by having a small amount of what they crave.” As both the years and the pounds add up, however, you may need to eat more of what you crave to get the same pleasant sensation.
Another Culprit: Glucose
Both aging and obesity can also bring changes to the way your body processes glucose—the sugar your body makes from food and uses for energy. These changes can lead to diabetes, which raises your risk for heart disease, blindness, amputations, and other conditions.
“Obesity increases the risk, and reduces the age of onset, for many diseases of aging,” Mattson says. “Over the long-term, even our brains are affected. Emerging evidence suggests that long-standing diabetes and obesity can lead to changes in brain cells that make them vulnerable to aging.”
As you move beyond your 50’s, you’ll probably need fewer calories. But it’s also important to maintain proper nutrition, so don’t skimp on healthy foods. Weighing too little or too much are linked to poor health, especially in older people.
Small Steps to Healthy Aging
- Commit to a healthy diet.
- Limit snacking.
- Drink plenty of water.
- Move more. Take the stairs and add walking breaks to your day.
- Get plenty of sleep.
- Limit alcohol use. Alcohol is high in calories and may worsen health conditions common among older adults.
- Avoid tobacco products.
Exercise and being active are important to your health. “It doesn’t matter what your age is; physical activity is good for you,” says Egan. Be sure to talk with your health care provider about safe ways to adjust your activity patterns as you get older. If you have a specific health issue that you’re concerned about – such as arthritis or a recent surgery – ask for tips to help you exercise safely. Work together to choose activities that are best for you.
Focusing on physical activity and healthy, nutritious eating are the keys to avoiding middle-age spread and the health problems that can come with it. NIH’s Go4Life exercise and physical activity campaign is designed especially for older adults so you may want to visit the Go4Life website for additional information.
