The Kellogg's Special K Slimmer for Summer Challenge is designed for people who are overweight i.e. with a Body Mass Index greater than 25. If your BMI is between 18 and 25, you're already within a healthy weight range and the challenge isn’t suitable for you.
To find out your body mass index (BMI), simply enter your details and leave the rest to Kellogg’s BMI Calculator!
To do this please enter your weight in either stones & pounds OR kilograms, and your height in feet & inches OR metres.
