The Ultimate Guide to Body Mass Index (BMI) & Your Health
Your Body Mass Index (BMI) is a simple yet effective indicator used to categorize an adult's weight relative to their height. While not a direct measure of body fat percentage, it provides a valuable starting point for understanding your risk for health conditions like heart disease, diabetes, and hypertension.
🍎 Healthy Range (18.5 - 24.9)
Maintaining a weight in this range is linked to improved longevity and lower metabolic risk. It is achieved through a combination of nutritional density and consistent physical activity.
⚖️ Understanding Composition
BMI cannot distinguish between muscle mass and fat mass. This is why athletes often have "Overweight" BMIs despite having very low body fat percentages. Use this tool as a guide, not a final diagnosis.

| 30.0+ | Obese | High risk (chronic disease) |
Frequently Asked Questions
How often should I calculate my BMI?
Monthly tracking is ideal. Daily fluctuations due to water retention or muscle gain can make frequent checks discouraging or inaccurate.
Does age affect BMI interpretation?
Yes. For seniors (65+), a slightly higher BMI (25-27) may actually be healthier and provide protection against osteoporosis and frailty.
