Not medical advice
The TDEE Calculator and the articles on tdeecalculator.tech are for general information and education. They are not medical, nutritional or dietary advice, and they do not replace advice from a doctor, registered dietitian or other qualified health professional.
Estimates only
Results are estimates based on published formulas (Mifflin-St Jeor, revised Harris-Benedict and Katch-McArdle) and standard activity factors. Real energy needs vary between people and can differ from any formula by 10% or more. Use results as a starting point and check them against real-world results.
Who should not rely on these results
Do not use this calculator to set a calorie deficit or diet plan without professional advice if you:
- are under 18;
- are pregnant or breastfeeding;
- have, or have had, an eating disorder;
- have a medical condition such as diabetes, thyroid disease, heart disease or kidney disease;
- take medicines that affect appetite, weight or metabolism.
Safe minimums
Eating below about 1,200 kcal a day (women) or 1,500 kcal a day (men) is not recommended without medical supervision.
