Terms of Use

Informational use

The calculators and educational content are provided for general informational purposes. They are not a substitute for professional medical, nutrition, or other individualized advice.

No guarantee of individual accuracy

Calculations can be mathematically correct while still being a poor representation of an individual's physiology. Results depend on the inputs, the chosen method, and the assumptions built into each equation.

Responsible use

Do not use the site to diagnose a condition, prescribe treatment, set extreme dietary restrictions, or make medication decisions. Use appropriate professional support for health decisions that require individualized assessment.

Third-party links

Some pages link to external references for methodology or public-health information. External sites have their own terms and privacy policies.

Accuracy and availability

We aim to keep the calculators and explanations accurate, but no static website can guarantee that every result or page will be error-free at every moment. Verify important health information with authoritative sources.
