Describe the features of a body mass index problem.?

Too low or too high. The body mass index or bmi is a ratio of height and weight. Normal is from18 to 25. Too low = underweight. 25 to 30 is overweight. Over 30 is obese.
BMI. Body mass index (bmi) uses a person's height and weight to estimate if they are maintaining a healthy weight. Accuracy and usefulness can vary depending on muscle mass, as a heavily muscled 200 lb man is obviously not the same thing as an obese 200lb man.
