Body Mass Index (BMI)
This animation explores how BMI changes for a given height with varying weights and explains why using BMI as an indicator of healthy body weight can be misleading in some cases.
Body mass index, or BMI, is a simple measurement of body fat based on height and weight. It can be used as an indicator of health or obesity. The animation tracks the BMIs for a range of weights at a given height (5' 10"), indicating the points at which a person could be classified as "overweight" or "obese." The animation also highlights one of the issues with using BMI: based on BMI alone, a very muscular person may be classified as obese.
This animation is a clip from a 2004 Holiday Lecture Series, The Science of Fat. Depending on students’ background, it may be helpful to pause the animation at various points to discuss different features.
