Episode 491 of 565 episodes

Dr Mark Porter puts the BMI, or bodymass index, to the test. BMI calculates whether someone is too fat, too thin or just right but how accurate is it?

He compares his results with other measures of body fat and discovers hidden risks. (Photo: Overweight man measuring his waist. Credit: Science Photo Library)
