Disclaimer

The calculators and content on this site are for general fitness information only and are not medical advice. Formulas such as Mifflin-St Jeor and BMI are population-level estimates — individual needs vary with health conditions, medications and body composition. Always consult a physician or registered dietitian before starting a diet, supplement or exercise program, especially if you have a medical condition.

Accuracy of results

We test every calculator against reference values and review our formulas regularly. However, results depend entirely on the numbers and assumptions you enter, and simplified models cannot capture every real-world factor. Use the results as a starting point, not a final answer.
