Official WHO Body Health Standards for General Adults
International guidelines for assessing body health
Quick Answer
The WHO (World Health Organization) establishes global body health standards, including BMI categories (underweight: <18.5, normal: 18.5-24.9, overweight: 25-29.9, obese: 30+), waist circumference limits (men: <94cm, women: <80cm), and body fat percentage ranges. These standards help identify weight-related health risks worldwide.
WHO BMI Classification
The WHO BMI classification is the most widely used system for assessing weight status globally. It provides a standardized method for comparing populations across different countries and cultures.
| Category | BMI Range | Health Risk |
|---|---|---|
| Underweight | < 18.5 | Increased risk of malnutrition, osteoporosis |
| Normal Weight | 18.5 - 24.9 | Lowest risk of weight-related diseases |
| Overweight | 25.0 - 29.9 | Increased risk of heart disease, diabetes |
| Obese Class I | 30.0 - 34.9 | Moderate risk of chronic diseases |
| Obese Class II | 35.0 - 39.9 | High risk of chronic diseases |
| Obese Class III | >= 40.0 | Very high risk of chronic diseases |

Key WHO Recommendations
- 1
Maintain a healthy BMI: Aim for a BMI between 18.5 and 24.9 to minimize disease risk.
- 2
Monitor waist circumference: Keep waist circumference within recommended limits to reduce abdominal obesity risk.
- 3
Achieve gradual weight loss: If overweight, aim to lose 5-10% of body weight over 3-6 months.
- 4
Combine diet and exercise: Adopt a balanced diet with regular physical activity for sustainable health.
