Lean Mass

Lean mass, also known as muscle mass or lean body mass, refers to the weight of an individual's muscles, bones, and organs, without the presence of fat. This term is often used in the context of fitness, health, wellness, and weight loss. Having a healthy amount of lean mass is essential for maintaining optimal physical functioning, endurance, and strength.

Importance of Lean Mass

Lean mass is important because it helps improve overall metabolism and increases the number of calories an individual burns at rest. People with higher amounts of lean mass tend to have a higher resting metabolic rate than those with higher amounts of body fat.

Having a healthy amount of lean mass also helps prevent age-related muscle loss, which can lead to decreased strength and mobility as people get older. Regular exercise and a balanced diet that includes sufficient protein are the best ways to maintain or increase lean mass.
