Question

Write the formula for Body Mass Index (BMI) and identify the categories for obesity.

Hint:

Always remember that BMI is calculated using height in meters squared and weight in kilograms.

Answer 1

Concept: Body Mass Index (BMI) is a measure used to assess whether a person has a healthy body weight in relation to their height. It helps in identifying underweight, normal weight, overweight, and obesity levels.
Step 1: Formula of BMI.
\[ \text{BMI} = \frac{\text{Weight in kilograms (kg)}}{\text{Height in meters (m)}^2} \]
Step 2: Categories of BMI (Obesity Levels).

• Underweight: BMI less than 18.5
• Normal Weight: BMI 18.5 – 24.9
• Overweight: BMI 25.0 – 29.9
• Obesity Class I: BMI 30.0 – 34.9
• Obesity Class II: BMI 35.0 – 39.9
• Obesity Class III (Severe Obesity): BMI 40.0 and above

Final Answer: The formula for BMI is: \[ \text{BMI} = \frac{\text{Weight (kg)}}{\text{Height (m)}^2} \] Obesity is classified into Class I (30–34.9), Class II (35–39.9), and Class III (40 and above) based on BMI values.
