Lean Body Mass (LBM) refers to everything in your body that isn’t fat—muscle, bone, water, and organs. Knowing your LBM helps you understand how your body composition impacts your metabolism, strength, and overall wellness.
Enter your height, weight, and sex above.
Our calculator estimates your:
Lean Body Mass (LBM) – your muscle, bone, and organ weight
Body Fat Mass – how many pounds of your total weight come from fat
Lean Body Percentage – the ratio of lean to total mass
This gives a clearer picture of your body composition and helps identify what’s driving your metabolism.
Your lean body mass is a foundation for every health goal. Depending on your numbers:
Lower-than-ideal LBM: We’ll support muscle rebuilding with high-quality protein, resistance training, and supplements.
Balanced LBM: Focus shifts to maintenance and metabolic stability.
High LBM: You may benefit from strategic nutrition to support performance and hormone function.
At Slym Wellness, your data drives your direction. We’ll help you align your results with a plan that strengthens metabolism, balances hormones, and supports long-term success.
