What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a medical metric used to classify an individual's weight relative to their height. By calculating the ratio of weight to squared height ($kg/m^2$), BMI provides a screening category to determine potential risk factors associated with body fat density.
Understanding BMI Range & Categories
Your BMI value puts you in one of four distinct health zones. Below is the official classification standard:
| BMI Range | Classification Status | Associated Health Risks |
|---|---|---|
| Below 18.5 | Underweight | Nutritional deficiency, lower immune response, osteoporosis. |
| 18.5 – 24.9 | Healthy Weight | Minimal risk of lifestyle-related metabolic disorders. |
| 25.0 – 29.9 | Overweight | Moderate risk of heart disease, high blood pressure, fatigue. |
| 30.0 and above | Obese | High risk of Type 2 Diabetes, severe joint stress, cardiovascular issues. |
Why Calculate BMI?
Although BMI does not distinguish between muscle mass and fat tissue (meaning athletes and bodybuilders might be categorized as "overweight" or "obese" despite having very low body fat), it is a helpful reference point for the general population. Knowing your classification helps design appropriate nutrition and fitness regimens.
