**Question:** According to the new guidelines, the body mass index cut off for overweight is -

A. 25-29.9 kg/m²
B. 20-24.9 kg/m²
C. 30-34.9 kg/m²
D. 18.5-24.9 kg/m²

**Core Concept:** Body Mass Index (BMI) is a mathematical formula used to estimate an individual's body fat based on their weight and height. It is calculated as weight divided by the square of height (kg/m²). The World Health Organization (WHO) provides guidelines for interpreting BMI values.

**Why the Correct Answer is Right:** According to the WHO, the normal BMI range is 18.5-24.9 kg/m². Overweight is defined as a BMI between 25-29.9 kg/m². This means that individuals with a BMI between 25 and 29.9 are considered overweight, indicating excessive body fat that may increase the risk of health complications.

**Why Each Wrong Option is Incorrect:**

A. 20-24.9 kg/m² (Option B) is the normal BMI range, not overweight.
C. 30-34.9 kg/m² (Option C) is the range for class II obesity, not overweight.
D. 18.5-24.9 kg/m² (Option D) is the normal BMI range, not overweight.

**Clinical Pearl:** Regularly monitoring BMI can help identify individuals at risk for health issues related to obesity, such as cardiovascular disease, diabetes, and certain types of cancer. Encouraging lifestyle modifications, including diet and exercise, can prevent or manage these health complications in overweight individuals.
