BMI (Body Mass Index) is a simple calculation used to assess whether a person has a healthy body weight for a given height. While it's not a perfect measure, as it doesn't directly account for factors like muscle mass, bone density, or fat distribution, it's a useful screening tool for identifying potential weight-related health risks.
BMI Categories:
Based on the calculated BMI, individuals are classified into different categories according to the World Health Organization (WHO):
- Underweight: BMI < 18.5
- Normal weight: BMI 18.5-24.9
- Overweight: BMI 25-29.9
- Obesity: BMI ≥ 30
BMI and Health:
- Low BMI (under 18.5) may indicate malnutrition, eating disorders, or other health issues.
- Normal BMI (18.5 to 24.9) is generally considered healthy.
- Higher BMI (25 and above) can indicate higher risks for conditions like heart disease, diabetes, and certain cancers.
However, it's important to note that BMI alone is not a comprehensive measure of health, and factors like muscle mass, fat percentage, and overall fitness should also be considered when assessing health risks.
