Common Questions
Our calculators use established scientific formulas widely used in clinical and research settings — the Mifflin-St Jeor equation for calories, WHO BMI classifications, the U.S. Navy method for body fat, and multiple peer-reviewed ideal weight formulas. Results are estimates based on population averages and should be used as a general guide, not a medical diagnosis. For personalised health advice, please consult a qualified healthcare professional.
