Medical disclaimer

These calculators provide general wellness and educational estimates for adults aged 18 or over. They do not diagnose, treat or prevent disease, replace a physician or registered dietitian, or provide emergency advice.

Calorie, energy, macro and protein results are starting estimates. Activity, body composition, health conditions and individual circumstances can change actual needs. If you are pregnant, have a medical condition or eating disorder, or need individual dietary guidance, consult an appropriately qualified professional.

The BMI result is a screening measure, not a diagnosis. See methods and sources for the equations, assumptions and supported input ranges.
