From estimate to evidence
Formulas estimate your metabolism; blood measures it. Thyroid, blood sugar and lipid markers show how it is actually running, with AI-powered analysis built around your results.
Key Points
- Uses the revised Harris-Benedict equation (Roza & Shizgal, 1984) to estimate basal metabolic rate
- BMR is the number of calories your body burns at complete rest to maintain vital functions like breathing, circulation, and cell production
- Select your sex for a personalised estimate. The equations differ because males typically have greater lean mass
- The full TDEE breakdown shows calories for each activity level from Sedentary (×1.2) through Extra Active (×1.9)
- BMR decreases with age, roughly 1-2% per decade after 20, which is one reason caloric needs change over time
