Understanding BMI and Eating Disorders

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight. It’s calculated by dividing weight in kilograms by height in meters squared. BMI helps identify potential health risks associated with weight.

Anorexia Nervosa

Anorexia nervosa is an eating disorder characterized by extreme weight loss, distorted body image, and intense fear of gaining weight. It primarily affects adolescent females but can occur in males. A BMI below 17.5 is a common indicator.

BMI Categories

  • Underweight: BMI < 18.5
  • Normal: BMI 18.5-24.9
  • Overweight: BMI 25.0-29.9
  • Obese: BMI ≥ 30.0

Warning Signs of Eating Disorders

  • Severe restriction of food intake
  • Excessive exercise
  • Preoccupation with weight and appearance
