Terms of Use

1. What this site is

TDEEcals.com is a free online tool that estimates your Total Daily Energy Expenditure based on information you provide. It is for informational and educational purposes only. It is not a medical device, a substitute for professional nutrition advice, or a diagnostic tool of any kind.

2. Not medical advice

The results generated by this calculator are estimates based on population-level formulas. They may not accurately reflect your individual metabolism. Nothing on this website should be taken as medical, nutritional, or clinical advice.

Before making significant changes to your diet, exercise routine, or calorie intake — particularly if you have any health condition — consult a qualified doctor or registered dietitian. This is especially important if you are pregnant, breastfeeding, have diabetes, or have a history of disordered eating.

3. Accuracy of results

We use established, research-backed formulas (Mifflin-St Jeor and Katch-McArdle) to calculate TDEE estimates. However, these formulas are not perfect — they're population averages. Individual results can vary based on genetics, health conditions, medications, hormonal factors, and other variables that no calculator can account for. Use the results as a starting point, not a definitive answer.

4. Acceptable use

You may use this site for personal, non-commercial purposes. You may not:

• Scrape, copy, or reproduce the content or code of this site without permission
• Use the site in any way that could damage, disable, or impair it
• Attempt to gain unauthorized access to any part of the site or its infrastructure
• Misrepresent the calculator's output as clinical or professional dietary guidance

5. Intellectual property

The design, written content, and code of TDEEcals.com are owned by TDEEcals. The underlying TDEE formulas themselves are in the public domain — they come from published scientific literature. You are welcome to link to this site or reference the content with proper attribution.

6. Limitation of liability

TDEEcals.com and its owner are not liable for any outcomes resulting from the use of this calculator — including but not limited to health changes, weight changes, or decisions made based on the results. You use this tool at your own discretion and responsibility.

7. Availability

We aim to keep TDEEcals.com available at all times, but we can't guarantee uninterrupted access. We may occasionally take the site down for maintenance, updates, or for reasons outside our control. We're not responsible for any inconvenience this causes.

8. Changes to these terms

We may update these terms from time to time. The updated version will always be on this page with a revised "Last updated" date at the top. Continuing to use the site after changes are posted means you accept the updated terms.
