  • BMI between 30 and 34.9 is classified as Class 1 Obesity.
  • BMI between 35.0 and 39.9 is classified as Class 2 Obesity.
  • BMI of 40 or greater is classified as Class 3 Obesity (severe).
  • BMI between 40 and 49.9, or 35 and 49.9 with obesity-related comorbidity, is considered morbidly obese.
  • BMI between 50 and 59.9 is categorized as super obese.
  • BMI between 60 and 69.9 is categorized as super super obese.
  • BMI greater than 70 is categorized as hyper obese.

Classification of Obesity

  • Factors to consider when diagnosing obesity include age, sex, hydration level, muscular composition, presence of fluid in non-circulatory spaces, and edema.
  • Waist circumference greater than 40 inches (men) or 35 inches (women) indicates abdominal obesity.
  • A waist-to-hip ratio of 0.9 or greater (men) or 0.85 or greater (women) indicates abdominal obesity.

Prader-Willi Syndrome

  • Prader-Willi Syndrome is a rare genetic disorder that begins around 2 years of age.
  • It's caused by a deletion or imprinting defect on chromosome 15.
  • Symptoms include constant hunger, rapid weight gain, unusual food-seeking behaviors, and complications related to obesity.
  • It also disrupts normal functions of the hypothalamus and results in problems with hunger, growth, sexual development, body temperature, mood, and sleep.

Nutrition Management

  • Meal plans and strict snack/meal times are critical.
  • Small portion sizes are advisable.
  • Encourage mindful eating during meals.
  • Emphasize a balanced and healthy diet.
