Changing your BMI

You can find information about managing your weight on the NHS website.
Why BMI isn’t always reliable
BMI might not be the best measure for everyone, because it can’t see the difference between fat, muscle and bone.
This means:
- Athletes or people with a lot of muscle may get an ‘overweight’ or ‘obese’ reading, even though their body fat is actually low.
- Older people may get a ‘healthy weight’ result even if they have too much body fat because they’ve lost muscle as they’ve aged.
Pregnancy will also affect a woman's BMI result. As their baby grows, they’ll gain weight, which will cause their BMI to go up.
