Body Mass Index (BMI) uses your height and weight to estimate body fat and assess weight-related health risk. Measuring both accurately ensures your BMI result reflects your true health status.

View Health IntelligenceWhat is a typical healthy BMI range?
A BMI between 18.5 and 24.9 is generally considered within the typical weight range for most adults. BMI is a general indicator, not a diagnostic measure — speak with a healthcare professional about your individual circumstances.
Does BMI account for muscle mass?
BMI does not distinguish between muscle and fat. Athletes may have a high BMI without being overweight. Consult a healthcare professional for a full assessment.
How often should I check my BMI?
Checking every 1–3 months is sufficient for most people. Saving results in Healio360 lets you track trends over time.
