Weight management

Check your weight and get help if you are overweight or underweight.

Check your weight

A good way to check if you and your family are keeping to a healthy weight is to check your body mass index (BMI). This will give you an upper and a lower range that is right for your height and age. You can also check the BMI of other members of your family, including your children.


Being underweight is not good for your health. Find out more about what you can do if you are concerned about yourself or someone else.


If you are overweight or obese, try to lose some weight. Aim to lose weight gradually up to 2lbs a week. Find out more about eating a healthy, balanced diet and how to maintain good health that can help you feel your best.  There is help available in the borough if you are trying to lose weight:

Weight management groups

If you have had an NHS Health Check, or are referred by your GP, have a BMI of 30+, or are Black, Asian or any other ethnic minority with a BMI of 27.5 or over, you can attend up to 12 weekly meetings for free and gain access to online tools for 12 weeks for Weight Watchers or Slimming World. This is because Black, Asian and other minority ethnic groups have a higher risk of developing some long-term (chronic) conditions, such as type 2 diabetes. 

You will be unable to attend these meetings for free if you have an eating disorder, are pregnant or have been a paid Weight Watchers member in last three months.  

Make sure that any group you decide to attend is one that is recommended by national guidance, for example, Slimming World, or Weight Watchers.
