Healthy BMI Calculation: Is a 54kg, 175cm Person Underweight?

To determine if a person has a healthy body mass index (BMI), you need to calculate their BMI using the formula: BMI = weight (kg) / height (m)^2.

Plugging in the given values, we get: BMI = 54 / (1.75)^2 = 17.8.

According to the World Health Organization (WHO), a healthy BMI for adults falls within the range of 18.5 to 24.9. Therefore, the model with a BMI of 17.8 falls below the healthy weight range and is considered underweight.
