Answer:
BMI, formerly called the Quetelet index, is a measure for indicating nutritional status in adults. It is defined as a person's weight in kilograms divided by the square of the person's height in metres (kg/m2). For example, an adult who weighs 70 kg and whose height is 1.75 m will have a BMI of 22.9
BMI is calculated to know about the nourishment of an adult.
Each BMI value indicate the nourishment status such as under weight, normal weight, over weight & obese.
♦ If BMI < 18.5, the person will be considered undernourished.
♦ If BMI > 25, the person will be considered overweight.
♦ If BMI > 40, the person will be considered obese.
♦ If BMI is between 18.5 & 24.9, the person has a healthy weight.
