If a woman has 28 as BMI what does this mean?

A Body Mass Index (BMI) of 28 is considered overweight for adults. It means the person weighs more than what is considered healthy for their height. To calculate your BMI, divide your weight in kilograms by the square of your height in meters. For example, a person who weighs 75 kilograms and is 1.75 meters tall would have a BMI of 24.5.
