💡 Pro Tip: BMI is a screening tool. Athletes with high muscle mass may show high BMI despite being healthy. Consider waist circumference and body fat percentage for a complete picture.
What is BMI?
Body Mass Index (BMI) is a measure of body fat based on height and weight. It's used worldwide to classify underweight, normal weight, overweight, and obesity in adults. While not perfect, it's a quick screening Tool for potential health risks.
BMI Categories
- Underweight: BMI less than 18.5 — may indicate malnutrition or eating disorders
- Normal: BMI 18.5-24.9 — considered healthy weight range
- Overweight: BMI 25-29.9 — increased risk of health conditions
- Obese: BMI 30 or higher — significantly increased health risks
Limitations of BMI
- Doesn't distinguish between muscle and fat — bodybuilders may show high BMI
- Doesn't account for age, gender, or bone density variations
- Waist circumference and body fat percentage are better health indicators
- Asian populations may have health risks at lower BMI (23 is overweight)
Tips for Healthy Weight Management
- Focus on balanced nutrition, not crash diets
- Aim for 150 minutes moderate exercise per week
- Track progress with measurements, not just BMI
- Consult doctor before starting any weight loss program
- Sleep 7-9 hours — poor sleep disrupts hunger hormones
