Weight Watchers weight assessment calculator - What is the BMI?



The Weight Watchers weight assessment calculator allows you to calculate your healthy weight and BMI. BMI stands for Body Mass Index and is a measure for human body weight in relation to health risks, based on an individual's weight and height. BMI is not a direct measure of body fat; it is the recommended method to assess weight status. Because it expresses the weight-height relationship, BMI provides a more accurate indication of health risks associated with being overweight or obese, than using body weight alone.

What does it all mean?

You may be wondering what do the BMI ranges mean. Experts generally consider a BMI below 20 to be underweight and a BMI of 20 to 25 to be healthy. BMIs of 25 to 30 are considered overweight, while a BMI over 30 is considered obese.
