Understanding Lean Body Weight

Lean body weight (LBW) represents the total weight of all non-fat tissues in your body, including muscles, bones, organs, and water. It's a crucial metric for assessing body composition and overall health status.

Unlike total body weight, lean body weight focuses on metabolically active tissue that burns calories and supports physical function. Higher lean body mass is associated with better metabolic health, bone density, and functional capacity.

Key Benefits:

  • Better metabolic health
  • Improved bone density
  • Enhanced functional capacity
  • Reduced chronic disease risk
