Health FAQs
A BMI between 18.5 and 24.9 is considered the “Healthy Weight” range for most adults according to the World Health Organization (WHO).
While BMI is a useful screening tool, it’s not a diagnostic of body fat or health. Checking it every 1-3 months can help you track long-term trends in your weight management.
BMI does not distinguish between muscle and fat. Highly muscular individuals may have a high BMI score despite having very low body fat percentages.
