Study Notes
Definition of Obesity
- Obesity is a disorder characterized by an accumulation of excess body fat due to an imbalance between energy intake and energy expenditure.
Diagnosis of Obesity
- Body Mass Index (BMI) is used to estimate body fat by dividing weight (kg) by height (m²).
- BMI categories:
- Healthy weight: 18.5-24.9 kg/m²
- Overweight: 25-29.9 kg/m²
- Obese: ≥30 kg/m²
- Exceptions: Athletes with large amounts of lean muscle mass
- Waist circumference (WC) measurement is used to screen for obesity, reflecting central abdominal fat.
- Normal WC: <94 cm (men), <80 cm (women)
- High risk: 94-102 cm (men), 80-88 cm (women)
- Very high risk: >102 cm (men), >88 cm (women)
Classes of Obesity
- Class I obesity: BMI 30-34.9 kg/m²
