Metabolism is the process by which your body converts food into energy. Many people believe that metabolism suddenly slows down at a certain age, but in reality, metabolic changes happen gradually and are influenced by lifestyle, muscle mass, hormones, and daily habits.

Understanding how metabolism changes over time can help you adapt your nutrition and lifestyle for better long-term health.

🔄 Metabolism in Your 20s
