What is Body Mass Index (BMI)?
BMI is a simple way to find out if you’re a healthy weight for your height.
Did you know that, after not smoking, being a healthy weight is the most important thing you can do to reduce your risk of cancer?
The healthiest BMI for you will depend on your ethnic group and other factors like how much muscle you have.
If your BMI is within the healthy range, that’s a great start. Ideally, aim for a BMI that’s as low as possible for you within your range.
BMI may be less reliable for some groups of people, including body builders, athletes, older people, pregnant women, children or those less than five feet (1.5m) tall.
What should you do if your BMI is outside the healthy range?
If you’re outside the healthy range, we recommend you talk to your GP before making any really big changes to your diet or level of physical activity.
But don’t let that stop you making small changes today. Losing just a few pounds is a great start, and can improve your health and lower your risk of cancer and other diseases.
