By working out your body mass index (BMI) you can tell if you are overweight for your height.

A BMI of:

• 18.5 to 24.9 means your weight is healthy for your height
• 25 to 29.9 means your weight is overweight for your height
• 30 or over means your weight is an unhealthy weight for your height (obese)

Even though your BMI reading may be only slightly overweight, this extra body weight (fat) could be contributing to your diabetes. For people who have a lot of muscle mass, BMI may not be a good indicator of body fat.
