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.

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.
