Body Mass Index (BMI) is a number calculated from a person’s weight and height. BMI provides an indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.
Women tend to believe they look their best at values between 20 to 22 and men are usually satisfied with a BMI of 23 to 25. If your BMI is between 17 to 22, your life expectancy is longer than average. You don’t need to lose weight. If your BMI is between 23 and 25, you are not considered overweight by most people. But if your BMI is 26 or more, that’s not good.
