BMI stands for Body Mass Index. We invite people with a BMI higher than 23 to join our online membership service, as it is above this level that the risk of diabetes begins to increase. People with a BMI higher than 25 are at increased risk of developing other weight-related health problems.
As an online member, your BMI will be re-calculated every time you update your weight profile. As you lose weight you'll see your BMI moving towards the healthy range - below 25
