What is Lean Body Mass?

Lean Body Mass (LBM) is the amount of weight you carry choose that is not body fat. It includes muscles, bones, organs, and water. Knowing your LBM is essential for athletes and those looking to track body composition more accurately than BMI alone.

Importance of Lean Mass

A higher percentage of lean body mass is associated with a higher basal metabolic rate (BMR). This means that individuals with more muscle mass burn more calories even at rest.

Health Tracking

Tracking LBM is particularly useful during weight loss journeys to ensure that the weight being lost is primarily fat, not valuable muscle tissue.
