Frequently Asked Questions

What is the difference between BMI and BMR?

BMI (Body Mass Index) measures body fat based on height and weight, categorizing you as underweight, normal, overweight, or obese. BMR (Basal Metabolic Rate) estimates the calories your body burns at rest. They serve different purposes: BMI assesses body composition while BMR guides calorie intake planning.

How accurate are these health calculators?

Our calculators use well-established medical formulas: for BMI, the standard WHO metric formula; for BMR, Mifflin-St Jeor (the most accurate); for body fat, the US Navy circumference method. Results are estimates and should be discussed with a healthcare professional for medical decisions.

Are my health measurements private?

Absolutely. All calculations happen entirely in your browser. Your height, weight, age, and other measurements never leave your device. We don't store, log, or transmit any personal health data.
