What is BMI and how it used in weight or dietary control?

Body mass index (BMI) is a measure of body fat based on height and weight. It is used to screen for weight-related health problems such as obesity, heart disease, stroke, type 2 diabetes, and some types of cancer.

BMI is calculated by dividing weight in kilograms by the square of height in meters. The result is a number that corresponds to a weight category:

* Underweight = <18.5

* Normal weight = 18.5–24.9

* Overweight = 25–29.9

* Obesity = ≥30

BMI is not a perfect measure of body fat, but it is a good starting point for assessing weight-related health risks. It is especially useful for people who are not very muscular, as muscle mass can skew the results.

BMI is used by doctors, dietitians, and other health professionals to help people manage their weight and reduce their risk of developing weight-related health problems. It can also be used by individuals to track their own weight loss or gain progress.

If you are concerned about your weight, talk to your doctor. They can help you determine your ideal weight and develop a plan to reach it.
