Health Recommendations
- BMI is a screening tool, not a diagnostic measure of body fat or health.
- It may overestimate body fat in athletes and underestimate it in older adults.
- For a more comprehensive assessment, combine BMI with waist circumference and body fat percentage.
Important: BMI is not a perfect measure. It does not account for muscle mass, bone density, overall body composition, or racial and sex differences. It should be used as a guide alongside other measurements. For personalised advice, please consult a Doctor.

Low risk (based on UK guidance)
Your alcohol consumption is within the UK low-risk drinking guidelines.

Sex at birth
Some ethnic groups have a higher risk of metabolic liver disease at lower BMI.
Estimated BMI: –
We use BMI and waist to estimate how much visceral (internal) fat may be affecting your liver.
Measure around your tummy at the level of your belly button, breathing out gently.
Why this matters: the more metabolic risk factors you have, the more likely your liver is affected.
Important: both metabolic factors and alcohol can contribute to liver damage.
This tool gives an estimate only ✔ For personalised advice or a liver health check, speak to a clinician.
Your liver health risk
Score: 0 / 20
Lower risk (based on these answers)
Your answers suggest a lower estimated risk of metabolic-related fatty liver disease. This does not rule out liver problems, particularly if you have symptoms or abnormal tests.
This checker is for general education only and does not diagnose liver disease or replace medical advice.
If you have right upper tummy pain, yellowing of the eyes/skin, dark urine, very itchy skin, swelling of the tummy or legs,
or you feel unwell, contact a doctor urgently. For a detailed assessment, blood tests or liver scan,
you may wish to book a private liver health check.
