As we age, many of us find ourselves questioning how our metabolism changes. The short answer is yes, metabolism does slow down with age, but it may not be as early as you might think.
When Does Metabolism Slow Down?
Women often attribute weight gain to a “slow metabolism,” but research indicates that our metabolism typically does not start to decline until our 60s. Here’s how it works:
- In Your 20s: Metabolism slows by about 3% each year, but this gradual decline levels off as you enter your 30s.
- After Age 60: The metabolism slows further at a rate of approximately 0.7% per year.
Why Does Metabolism Slow Down?
Several factors contribute to the slowing of metabolism as we age:
- Slower Food Breakdown: As we age, our bodies break down food more slowly, resulting in leftover calories that can turn into fat.
- Decreased Activity: Aging often leads to decreased physical activity due to injuries, joint pain, lack of resources, or reduced social involvement. A less active lifestyle equals lower calorie burn.
- Changes in Appetite: With age, energy needs decrease, which can lead to a reduced appetite. Additionally, changes in vision, sense of smell, and taste may further diminish our desire to eat.
- Loss of Muscle Mass: Starting around age 30, people typically begin to lose muscle mass, with a more pronounced acceleration after age 65 for women and 70 for men. Since muscle burns more calories than fat, this loss can contribute to a slower metabolism.
- Dietary Changes: As we age, socializing more often can lead to dietary changes, such as increased alcohol consumption, which may contribute to weight gain.
Take Action!
The good news is that you can take proactive steps to manage your metabolism and combat age-related weight gain.
