Higher muscle mass positively affects the resting metabolic rate (RMR), as muscle tissue burns more calories at rest compared to fat tissue. Individuals with greater muscle mass tend to have more efficient metabolisms, which can aid in weight management and fat loss. Moreover, increasing muscle mass through resistance training can lead to enhanced overall strength, improved body composition, and reduced risk of chronic diseases. Maintaining and building muscle is essential for long-term metabolic health and supports overall physical fitness and well-being.
