How to Use the Anorexic BMI Calculator

The Anorexic BMI Calculator is a digital tool used to determine whether your body mass index (BMI) falls within the anorexic range (typically below 17.5).

This tool is helpful for educational, clinical awareness, and self-monitoring purposes, especially for individuals concerned about their body weight and health risks associated with undernutrition.

What is BMI?

BMI is a value derived from your height and weight. It helps categorize your body size as:

Underweight
Normal weight
Overweight
Obese

In this context, BMI values below 17.5 are considered to fall within the anorexic or severely underweight category.
