14 Sneaky Things Slowing Down Your Metabolism After 40

2. Muscle Mass Decline: The Unseen Metabolic Enemy

Muscle mass naturally decreases with age, a condition known as sarcopenia. This decline begins as early as the 30s but becomes more pronounced after 40. Muscle tissue is metabolically active, meaning it burns more calories at rest compared to fat tissue. Therefore, a decrease in muscle mass results in a slower metabolism. This not only makes weight management more challenging but also affects overall strength and mobility. Incorporating strength training exercises into your routine can help counteract muscle loss, thereby boosting metabolism and improving overall health.
