What is a healthy BMI range for adults?

A healthy BMI ranges from 18.5 to 24.9 for most adults. However, this can vary by age, gender, and ethnicity. For women over 40, a slightly higher BMI (up to 27) may still be considered healthy. Athletes with high muscle mass may also have elevated BMI scores while maintaining low body fat percentages.

Is BMI accurate for athletes and muscular individuals?

BMI has limitations for athletes and highly muscular individuals because it doesn't distinguish between muscle and fat mass. Athletes may have a high BMI (25-30) but low body fat percentage due to increased muscle mass. For more accurate assessment, combine BMI with body fat percentage, waist circumference, or body composition analysis.

Does BMI change with age?

Yes, healthy BMI ranges can shift slightly with age. Adults over 65 may have optimal health at BMI 25-27 rather than the standard 18.5-24.9. This is because moderate fat reserves in older adults can provide protection against illness and bone loss. Always consult healthcare providers for age-appropriate health assessments.

What should I do if my BMI is outside the healthy range?

If your BMI is below 18.5 (underweight) or above 25 (overweight), consult a healthcare provider or registered dietitian. They can assess your overall health, body composition, and lifestyle factors. Recommendations may include balanced nutrition, regular physical activity, stress management, and medical evaluation to rule out underlying conditions. Gradual, sustainable changes are most effective.

What is BMI and Why It Matters

BMI (Body Mass Index) is a simple calculation using your height and weight to estimate body fat percentage. It helps you understand if you are underweight, in the healthy range, overweight, or obese. Monitoring your BMI can highlight potential risks like diabetes or heart disease.

How to Calculate BMI at Home

BMI = weight (kg) / height (m)²
Example: If you weigh 70 kg and are 1.75 m tall → 70 ÷ (1.75×1.75) = 22.9.
