Body Mass Index (BMI) is a good way to check if you’re a healthy weight.
You can use the healthy weight calculator to find out your BMI, and get helpful information and advice. http://www.nhs.uk/Tools/Pages/Healthyweightcalculator.aspx
For adults, BMI is a measure of whether you’re a healthy weight for your height.
If you have a BMI above the healthy range you are at raised risk of the serious health problems linked to being overweight, such as type 2 diabetes, heart disease and certain cancers.
