FAQ
BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat, so athletes may have a "high" BMI despite being healthy. It also doesn't account for age-related changes in body composition. Use it alongside other health indicators.
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic functions (breathing, circulation, cell production) while at complete rest. It's calculated using the Mifflin-St Jeor equation, the most accurate widely-used formula.
For adults 20+, a BMI between 18.5 and 24.9 is considered healthy by WHO guidelines. For Asian populations, some health organizations use slightly lower thresholds (23 for overweight, 27.5 for obese). Always consult your doctor for personalized guidance.
