Understand the concept of Body Mass Index (BMI), which is a measure of body fat based on height and weight that applies to adult men and women.
Recognize that BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters.
Learn the BMI categories: underweight (BMI less than 18.5), normal weight (BMI 18.5–24.9), overweight (BMI 25–29.9), and obesity (BMI 30 or more).
Identify that a BMI of 30 or more falls into the category of obesity, which is a condition characterized by excessive body fat that increases the risk of health problems.
Differentiate between obesity and other eating disorders such as anorexia nervosa and bulimia nervosa, which are characterized by abnormal eating habits and concerns about body weight and shape, but not defined by BMI alone.
