Terms of Use

Last updated: 15 August 2026

By using this site you agree to the terms below. If you do not agree with them, please do not use the site.

1. This is education, not medical advice

Everything on FitCalc — calculators, guides, tables, examples — is general educational information. It is not medical advice, diagnosis or treatment, and it does not create a coach–client or practitioner–patient relationship.

Talk to a qualified healthcare professional before changing how you eat or train, particularly if you are pregnant or breastfeeding, have diabetes or another metabolic condition, have cardiovascular disease, take medication that must be paired with food, are under 18, or have a history of disordered eating.

2. Calculators produce estimates

Every tool on this site returns an estimate derived from published equations and general population data. Estimates do not account for your medical history, medications, body composition, or individual metabolic variation. They are a starting point to be adjusted against what actually happens over the following weeks, not a prescription.

3. You use this at your own risk

Exercise and dietary change carry inherent risk. You are responsible for deciding what is appropriate for you and for stopping if something hurts. To the fullest extent permitted by law, FitCalc and Coach Ohm accept no liability for loss or injury arising from use of the information on this site.

4. Accuracy

The content here is prepared carefully and reviewed by a certified trainer, and it may still contain errors or become out of date. If you find something wrong, please write to contact@crafnia.com — corrections are welcome and get made.

5. Intellectual property

The text, calculators and design on this site belong to their author. You are welcome to read, use and link to them. Republishing substantial portions elsewhere without permission is not permitted.

6. External links

This site links to other websites that we do not control and are not responsible for.

7. Advertising

This site carries third-party advertising. Advertisements are not endorsements, and we do not control the products or claims that appear in them.

8. Changes

These terms may be updated. The date at the top of this page shows when they last were.
