The Metabolism Myth

Contrary to popular belief, metabolism doesn't necessarily slow dramatically with age. Recent research suggests our metabolism stays relatively stable from ages 20 to 60. The real culprits behind age-related weight gain are often lifestyle changes and hormonal shifts.

Muscle Mass Matters

As we age, we naturally lose muscle mass, a process called sarcopenia. Muscle burns more calories than fat, even at rest. So less muscle means fewer calories burned daily. Strength training can help maintain muscle mass and boost metabolism.
Age-related weight gain is influenced by lifestyle changes, hormonal shifts, and muscle mass loss, rather than a dramatic slowdown in metabolism.

Hormonal Havoc

Hormonal changes play a big role in age-related weight gain, especially for women. Menopause leads to a drop in estrogen, which can increase appetite and promote fat storage, particularly around the abdomen. For men, declining testosterone can contribute to muscle loss and weight gain.

Lifestyle Shifts

As we age, we often become less active due to work demands, health issues, or simply habit. We may also eat more or make poorer food choices. These lifestyle factors, more than age itself, contribute significantly to weight gain over time.
