Understanding your BMI result

Underweight

Being underweight could be a sign you're not eating enough or you may be ill. If you're underweight, a GP can help.

Healthy weight

Keep up the good work! For tips on maintaining a healthy weight, check out the food and diet and fitness sections.

Overweight

The best way to lose weight if you're overweight is through a combination of diet and exercise.
The BMI calculator will give you a personal calorie allowance to help you achieve a healthy weight safely.

Obese

The best way to lose weight if you're obese is through a combination of diet and exercise, and, in some cases, medicines. See a GP for help and advice.

Black, Asian and other minority ethnic groups

Black, Asian and other minority ethnic groups have a higher risk of developing some long-term (chronic) conditions, such as type 2 diabetes.
These adults with a BMI of:

  • 23 or more are at increased risk
  • 27.5 or more are at high risk

Why waist size also matters

Measuring your waist is a good way to check you're not carrying too much fat around your stomach, which can raise your risk of heart disease, type 2 diabetes and stroke.

You can have a healthy BMI and still have excess tummy fat, meaning you're still at risk of developing these conditions.

  1. Find the bottom of your ribs and the top of your hips.
  2. Wrap a tape measure around your waist midway between these points.
  3. Breathe out naturally before taking the measurement.
Regardless of your height or BMI, you should try to lose weight if your waist is:
  • 94cm (37ins) or more for men
  • 80cm (31.5ins) or more for women
You're at very high risk and should contact a GP if your waist is:
  • 102cm (40ins) or more for men
  • 88cm (34ins) or more for women
