Final answer:
BMI considers an individual's weight and height to estimate body fat content, but does not account for age or gender. It classifies individuals as normal weight, overweight, or obese based on specific BMI ranges.
Step-by-step explanation:
Body Mass Index (BMI) considers someone's weight and height. BMI is an estimate of body fat content calculated by dividing a person's weight in kilograms by the square of their height in meters. A BMI ranging from 18-24.9 is considered normal weight, 25-29.9 is considered overweight, and greater than 30 is considered obese.
However, BMI does not consider attributes such as age or gender, which can also impact body composition. BMI's limitations include not accounting for muscle mass, which may lead to an underestimation of body fat in muscular individuals or an overestimation in those with less muscle mass.
