Understanding BMI and Your Health
What is BMI?
Body Mass Index (BMI) is a simple calculation using your height and weight to estimate body fat. It's a screening tool that can indicate whether you're:
- Underweight (BMI < 18.5)
- Normal weight (BMI 18.5-24.9)
- Overweight (BMI 25-29.9)
- Obese (BMI ≥ 30)
BMI Limitations
Who BMI Works For
- Most adults 18-65
- General population screening
- Tracking weight trends
Who BMI May Misclassify
- Athletes with high muscle mass
- Pregnant women
- Elderly with muscle loss
- Children (use BMI-for-age)
Healthy Weight Management Tips
- Balanced diet: Focus on whole foods, fruits, vegetables, lean proteins
- Regular exercise: Aim for 150+ minutes of moderate activity weekly
- Hydration: Drink plenty of water throughout the day
- Sleep: Get 7-9 hours of quality sleep nightly
- Stress management: Practice mindfulness or meditation
Pro Tip: While BMI is a useful screening tool, it doesn't measure body fat directly. For a more complete health assessment, consider body composition tests like skinfold measurements, DEXA scans, or bioelectrical impedance analysis.
