Understanding Your Results

What is BMI?

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

While BMI is a useful screening tool, it doesn't directly measure body fat and may not account for muscle mass, bone density, or ethnic differences. Athletes with high muscle mass may have a high BMI without excess fat.

Body Shape Analysis

Your body shape (apple, pear, hourglass, etc.) can indicate where you store fat, which affects health risks differently:

Apple shape: Higher risk for heart disease and diabetes (fat around abdomen)
Pear shape: Lower health risk (fat around hips and thighs)
Hourglass: Balanced fat distribution
Rectangle: Even fat distribution with less waist definition
