Metabolism plays a crucial role in weight management, dictating how efficiently the body converts food into energy. A higher metabolic rate allows for greater calorie expenditure, aiding in weight loss or maintenance. Factors influencing metabolism include genetics, age, muscle mass, and activity level. Regular exercise, particularly strength training, can increase lean muscle mass, subsequently boosting metabolic rate. Additionally, certain dietary practices, such as consuming adequate protein, can enhance metabolic function. Understanding metabolism is key to developing effective strategies for achieving and maintaining a healthy weight.
