BMI, or body mass index, is a generalized charting system utilized in the determination of healthy weight to height ratios. Accordingly, the BMI system is broken down into several categories for determination of whether a person is under, over, or within a safe level of weight based on their height.
The World Health Organization (WHO) report says, BMI less than 18.5 is counted as underweight and BMI above 25 is counted as overweight.
The following BMI categories table falls into the adults who are over 20 years old.
| BMI Category | BMI Range (kg/m2) | Health Risk |
|---|---|---|
| Underweight | Below 18.5 | Malnutrition Risk |
| Normal weight | 18.5 - 24.9 | Low Risk |
| Overweight | 25 - 29.9 | Enchanced Risk |
| Moderately Obese | 30 - 34.9 | Medium Risk |
| Severely Obese | 35 - 39.9 | High Risk |
| Very Severely Obese | Above 40 | Very high Risk |
