Editorial Guidelines
Last updated: June 12, 2026
Our editorial process and standards for Lean Mass Calculator. We prioritize scientific accuracy, transparency, and peer-reviewed sources.
Our Commitment to Accuracy
At Lean Mass Calculator, our primary goal is to provide calculators and health tools that are scientifically sound, transparent, and easy to use. We do not invent formulas; we implement peer-reviewed equations used in clinical settings.
Formula Selection
Every calculator on our site relies on established mathematical formulas that have been published in peer-reviewed medical or scientific journals (e.g., Boer, James, Hume).
We always state the exact formula being used and provide the mathematical breakdown so users can verify the results themselves.
Reference Ranges
When we categorize results (such as body fat percentages or BMI ranges), we strictly adhere to guidelines published by recognized health organizations, including the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the American Council on Exercise (ACE).
No Medical Advice
Our content and tools are for informational and educational purposes only. They are not intended to substitute for professional medical advice, diagnosis, or treatment. We clearly communicate this limitation across our site.
Review Process
All tools and articles are reviewed by our editorial team before publication. We periodically update our calculators to ensure they reflect the most current scientific consensus. If an error is found, we correct it promptly and transparently.
