1. What is Lean Body Mass?

Lean Body Mass (LBM) refers to the weight of everything in your body except fat. This includes muscles, bones, organs, and water. Knowing your LBM is important for fitness, nutrition planning, and medical assessments.

2. How Does the Calculator Work?

The calculator uses the Boer equation for men:

Where:

• \( Weight \) — Body weight in kilograms (kg)
• \( Height \) — Height in centimeters (cm)

Explanation: The equation estimates lean body mass based on weight and height, with different coefficients for different genders.

3. Importance of LBM Calculation

Details: LBM is used to assess nutritional status, guide protein requirements, calculate medication dosages, and evaluate fitness progress.

4. Using the Calculator

Tips: Enter weight in kg, height in cm, and select gender. All values must be valid (weight > 0, height > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this LBM calculation?
A: The equation provides a reasonable estimate but may not be as accurate as methods like DEXA scans or underwater weighing.

Q2: What's the difference between LBM and muscle mass?
A: LBM includes all non-fat components (muscles, bones, organs, water), while muscle mass specifically refers to skeletal muscles.

Q3: Why is LBM important for athletes?
A: Athletes monitor LBM to track muscle development and optimize performance, as it correlates with metabolic rate and strength.

Q4: How does LBM change with age?
A: LBM typically decreases with age due to muscle loss (sarcopenia), especially without resistance training.

Q5: Can I use this for weight loss tracking?
A: Yes, tracking LBM helps ensure weight loss comes from fat rather than muscle when dieting.
