Answer:
The answer is BMI. This index has ranges that help indicate whether one is underweight, normal weight, overweight or obese. To calculate BMI, the following formulae are used;
Weight (kg)/height (m) ^ 2
To check your BMI Categories:
Underweight = <18.5
Normal weight = 18.5–24.9
Overweight = 25–29.9
Obesity = BMI of 30 or greater
