Protein Calculation Formula:
| From: | To: |
The Lean Body Mass Protein calculation determines daily protein requirements based on an individual's lean body mass (LBM) and activity level. This method provides a more personalized protein recommendation than weight-based calculations.
The calculator uses the simple formula:
Where:
Typical Factor Values:
Details: Accurate protein calculation helps maintain muscle mass, supports recovery from exercise, and ensures adequate nutrition for metabolic functions. It's particularly important for athletes, bodybuilders, and those in muscle maintenance or growth phases.
Tips: Enter your lean body mass in kg and select an appropriate protein factor based on your activity level. The default factor of 2.2 g/kg is suitable for most active individuals.
Q1: How is lean body mass different from total weight?
A: Lean body mass includes muscles, bones, organs and water - everything except fat. It's typically 70-90% of total body weight.
Q2: What's the difference between this and total weight protein calculation?
A: Calculating based on LBM is more accurate as fat tissue requires minimal protein, while muscle tissue has high protein needs.
Q3: Can I use this for weight loss?
A: Yes, maintaining adequate protein during weight loss helps preserve muscle mass while losing fat.
Q4: When should I adjust the protein factor?
A: Increase the factor if you're highly active, recovering from injury, or trying to build muscle. Decrease if sedentary or with certain medical conditions.
Q5: Are there risks to too much protein?
A: While healthy individuals can tolerate high protein, those with kidney disease should consult a doctor before increasing protein intake.
