Terms and Conditions

TDEE Calculator Kit provides free calculators and articles covering total daily energy expenditure, basal metabolic rate, macronutrients, body composition, hydration, and calories burned during activity. The site is operated by Osama Amir Khan, a clinical pharmacist with an MPhil in Pharmacology.

The calculators and articles are for general information and education. They are not a diagnosis, a treatment plan, or a substitute for advice from your doctor, dietitian, or pharmacist. Speak with a qualified professional before starting a diet, changing medication, or beginning a new training programme, especially if you are pregnant, breastfeeding, under 18, over 65, or living with a medical condition such as diabetes, thyroid disease, PCOS, or an eating disorder. If you have a medical emergency, contact your local emergency service.

Our calculators use published equations such as Mifflin-St Jeor, Katch-McArdle, and MET values from the 2024 Adult Compendium of Physical Activities. These equations produce estimates. Real energy expenditure varies with muscle mass, genetics, hormones, sleep, medication, and measurement error, so treat any number you see here as a starting point and adjust it based on how your body responds over two to three weeks. We do not guarantee any particular health, weight, or performance outcome.

You can use every calculator without an account. If you create one, you agree to give accurate details, keep your password private, and take responsibility for activity under your account. You must be at least 13 years old to register. We may suspend or remove an account that is used for abuse, spam, scraping, or anything unlawful. You can ask us to delete your account at any time by emailing tdeecalculatorkit@gmail.com.

• Do not attempt to break, overload, or gain unauthorised access to the site.
• Do not scrape, copy, or republish our calculators, tables, or articles at scale without written permission.
• Do not upload content that is unlawful, harmful, or infringes anyone's rights.
• Do not present our results as professional medical advice to other people.

Food entries, workout logs, weight records, and other data you save stay yours. You grant us permission to store and display that data back to you so the dashboard works. We may use aggregated, de-identified statistics to improve the site.

The text, design, calculator logic, charts, and branding on this site are owned by TDEE Calculator Kit unless credited otherwise. You may link to our pages and quote short extracts with clear attribution and a link back. Republishing full articles or copying calculator code is not allowed without permission.

Some pages link to research papers, nutrition databases, and other websites. We do not control those resources and are not responsible for their content or their privacy practices. Nutrition values shown in the food counter come from USDA FoodData Central and may differ from the label on your product.

We work to keep the site online, but access may be interrupted for maintenance, updates, or reasons outside our control. Features may be added, changed, or removed without notice.

To the fullest extent permitted by law, TDEE Calculator Kit and its author are not liable for any loss, injury, or damage arising from your use of the site, including decisions made on the basis of a calculator result. You use the site at your own risk.

We may revise these terms as the site develops. The date at the top shows the current version, and continued use after an update means you accept the revised terms.

For anything related to these terms, email tdeecalculatorkit@gmail.com. See also our Privacy Policy.
