Body Mass Index (BMI) is one way you can determine if your present weight is putting your health at risk. It is for adults to determine if 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.
Some adults who have a lot of muscle may have a BMI above the healthy range. For example, professional rugby players can have an ‘obese’ BMI result despite having very little body fat. However, this will not apply to most people.
Your BMI can be calculated by taking your weight and dividing it by your height squared. If you know your current height and weight, you can work out which weight range you are in by using the chart below.
These are the weight ranges, set by the World Health Organisation:
- If your BMI is less than 18.4 you are underweight for your height
- If your BMI is between 18.5 and 24.9 you’re an ideal weight for your height
- If your BMI is between 25 and 29.9 you’re over the ideal weight for your height
- If your BMI is between 30 and 39.9 you are obese
- If your BMI is over 40 you are very obese
