Do you know what your Body Mass Index (BMI) is?
The body mass index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. It gives a measure which can be used to determine if you are underweight, of normal weight, overweight or obese. This is not a medical assessment – if you’re worried about your health please speak to your GP or a health professional. This BMI guide is for adults. Some ethnicities including south Asian people have an increased risk of health problems like type 2 diabetes with a BMI of 23 or more. Your BMI can help you to set goals and plan your health journey.
