BMI stands for Body Mass Index, and it is a measure of body fat based on height and weight. The BMI scale ranges from less than 18.5 (underweight) to 30 or greater (obese), with a normal weight range between 18.5 and 24.9.

Here is a breakdown of the BMI categories:

Underweight: less than 18.5

Normal weight: 18.5 - 24.9

Overweight: 25 - 29.9

Obese: 30 or greater

Disclaimer It is important to note that the BMI scale is not always an accurate measure of body fat, as it does not take into account muscle mass, bone density, and other factors. It is always best to consult a healthcare professional for personalized advice on body composition and weight management.

According to the World Health Organization (WHO), obesity can be classified into three categories based on BMI:

Class 1 obesity: BMI between 30 and 34.9

Class 2 obesity: BMI between 35 and 39.9

Class 3 obesity: BMI of 40 or higher

Each class of obesity carries varying degrees of health risks, including an increased risk for type 2 diabetes, heart disease, stroke, and certain types of cancer. It is important to seek medical advice and make healthy lifestyle changes if you fall into one of these categories.
