Which BMI value defines underweight?

Explanation:
BMI is a measure of body mass relative to height, calculated as weight in kilograms divided by height in meters squared. It categorizes adults into underweight, normal weight, overweight, and obesity. The boundary for underweight is a BMI below 18.5, a point at which body mass is considered too low to support health and is linked to higher risks like malnutrition and weakened immunity. Normal weight starts at 18.5 and goes up to 24.9, with higher ranges indicating overweight or obesity. So, the underweight category is defined by a BMI value below 18.5.
