Understanding BMI: What Your Body Mass Index Means
What is BMI?
BMI (Body Mass Index) is a measure that uses your height and weight to estimate if you are at a healthy weight. BMI = weight (kg) / height (m)^2. It is a simple screening tool used worldwide.
BMI Categories
Underweight: below 18.5 | Normal: 18.5 - 24.9 | Overweight: 25 - 29.9 | Obese: 30 and above. These ranges apply to most adults regardless of age or sex.
Calculating Your BMI
1. Measure your weight in kilograms. 2. Measure your height in meters. 3. Use the formula BMI = kg/m^2. Or simply use our free BMI calculator. The tool instantly calculates your BMI and shows your category.
Limitations of BMI
BMI does not directly measure body fat. Athletes with high muscle mass may have a high BMI without excess fat. It is a screening tool, not a diagnostic tool.
Maintaining a Healthy BMI
Regular exercise, balanced nutrition, adequate sleep, and stress management all contribute to maintaining a healthy BMI. Small, consistent changes are more effective than extreme diets.
