What is a normal BMI?

A BMI between 18.5 and 24.9 is considered normal/healthy. Below 18.5 is underweight, 25–29.9 is overweight, and 30+ is obese.

How is BMI calculated?

BMI = weight (kg) ÷ height² (m²). In imperial units: BMI = 703 × weight (lb) ÷ height² (in²).

Is BMI accurate for athletes?

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in the elderly with low muscle mass. Combine with waist circumference for better assessment.

What is a healthy BMI for women?

The same ranges apply: 18.5–24.9 is considered healthy for both men and women, though body composition differs.

How do I lower my BMI?

A combination of caloric deficit, regular aerobic exercise, and strength training lowers BMI most effectively. Consult a healthcare provider for personalized guidance.
