Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. It is an inexpensive and easy-to-perform method of screening for weight categories that may lead to health problems.
A person’s Body-Mass Index, or BMI, helps them check whether they’re a healthy weight for their height. If a person weighs less or more than the recommended weight for their height, it could lead to health issues in the future. While BMI is not the only factor individuals should consider while working on their health and fitness, it is a good starting point. To understand what your BMI is, you need to know your height and weight. You can then check your BMI against the BMI chart:
The numbers on the chart will help you understand if you’re underweight, a healthy weight, overweight or obese.
- Underweight – BMI less than 18.5
- Normal weight – BMI between 18.5 and 24
- Overweight – BMI between 25 and 29.9
- Obese – BMI above 30
Researchers have divided obesity into three categories
- Class I – BMI 30 to 34.9
- Class II – BMI 35 – 39.9
- Class III – BMI 40+
