💡Tips & Knowledge
- •BMI = weight(kg) ÷ height(m)². Under 18.5=underweight, 18.5–25=normal, 25+=obese. BMI 22 is statistically healthiest
- •Always check body fat % alongside BMI — muscular people may have high BMI but healthy body fat
- •BMR (Basal Metabolic Rate) is calculated using the Harris-Benedict formula. Eating below BMR causes muscle loss
- •Ideal weight = height(m)² × 22. Aesthetic weight = height(m)² × 20. Set realistic goals to stay healthy
❓Frequently Asked Questions
Q.How is BMI calculated?
A. BMI = weight(kg) ÷ height(m)². Under 18.5: underweight. 18.5–25: normal. 25–30: overweight. 30+: obese. BMI 22 is statistically associated with the lowest disease risk.
Q.What is BMR vs TDEE?
A. BMR (Basal Metabolic Rate) is how many calories you burn at complete rest. TDEE (Total Daily Energy Expenditure) multiplies BMR by your activity level to get your actual daily calorie burn.
Q.How accurate are these calculations?
A. Results use the Harris-Benedict formula and standard equations — they are statistical estimates, not medical measurements. Consult a healthcare professional for clinical decisions.
Q.What body fat % is healthy?
A. For men: 5–13% (athlete), 15–25% (normal), 28%+ (obese). For women: 10–20% (athlete), 20–30% (normal), 35%+ (obese). These are general reference ranges.
