Fatty liver calculators
Each of these implements a published, named instrument and shows the cut-off values from its own literature. Nothing you enter leaves your browser — there is no server to send it to.
FIB-4 Calculator
FIB-4 is a non-invasive score that uses four values already on a routine blood panel to estimate how likely advanced liver scarring is. It is the first-line triage tool in most fatty liver pathways.
Open →AST/ALT Ratio Calculator
The ratio between two liver enzymes, AST and ALT, is one of the oldest clues to what is driving a raised liver test.
Open →BMI Calculator
Body mass index is a rough screen, not a diagnosis — but excess body weight is the single strongest modifiable driver of metabolic fatty liver disease.
Open →Waist-to-Height Ratio
Where fat sits matters more to the liver than how much you weigh. Waist-to-height ratio is the simplest way to capture that at home.
Open →Weight Loss Target
Guidelines for metabolic fatty liver disease are written in percentages of body weight, not in target weights. This turns those percentages into your numbers.
Open →Daily Calorie Calculator
Gradual weight loss is what the evidence supports in fatty liver. This estimates your daily energy needs so a deficit can be a planned number rather than a guess.
