See what BMI cannot

BMI is a ratio of height and weight, not a picture of your health. Blood biomarkers show the metabolic and hormonal detail underneath, with AI-powered analysis built around your results.

Key Points

  • Calculated as weight (kg) divided by height (m) squared, the standard WHO formula used worldwide
  • WHO classifications: Underweight < 18.5, Normal 18.5-24.9, Overweight 25-29.9, Obese ≥ 30
  • BMI does not distinguish between muscle and fat. Muscular individuals may have a high BMI without excess body fat
  • Best used alongside other measurements such as waist circumference, body fat percentage, and blood markers
  • BMI is a screening tool, not a diagnostic measure. Consult a healthcare professional for personalised assessment
