Fatty liver: the organ that responds to sugar first
An ultrasound “for another reason,” and the report says “signs of fatty hepatosis.” You don’t drink. You don’t understand. The explanation is sugar: half of it, fructose, is processed only by the liver, and it turns the excess into fat and stores it in itself. One in four adults has this liver, and almost no one knows until they have their ALT tested. Section — blood sugar.
Why fructose, not fat
All body cells use glucose. Only the liver uses fructose, and it has no “brake”: whatever arrives gets processed, and the excess becomes fat right there. Sugar is 50% fructose, honey is 40%, juices and “fruit” drinks are almost pure fructose, and agave is 90%. Contrary to intuition, dietary fat does not accumulate in the liver—it goes into the blood and tissues. Hence the paradox: low-fat yogurts with sugar promote fatty liver, while an omelet cooked in oil does not.

How to suspect and check
| What | What it means |
|---|---|
| ALT above 25-30 U/L in women | the liver is responding; the laboratory “normal up to 40” is outdated |
| AST, GGT elevated | additionally |
| Triglycerides above 1,7 | the liver makes fat from sugar |
| Waist from 80 cm | visceral fat occurs together with liver fat |
| Ultrasound: “increased echogenicity,” “hepatosis” | fat in the liver is visible |
| FLI index, elastography | more accurate, as prescribed |
Why it is dangerous and how it goes away
Fatty liver responds less well to insulin—this is the first stage of insulin resistance, diabetes and heart disease. In some people, inflammation and fibrosis develop over the years. But the liver recovers faster than any other organ: without sugar, fructose and flour, fat leaves it in 2-4 months, and ALT falls before the numbers on the scale. Add walking, an eating window—the pause gives the liver time to burn its reserves—and coffee, for which there is evidence of liver protection. The swings that make it grow are blood sugar swings; insulin in full — insulin resistance in women.
What to remove first
- Juices, including freshly squeezed ones—a glass of orange juice = 6 spoonfuls of fructose
- Sugar, honey, syrups, agave
- Dried fruit and “healthy” bars
- Fruit in large quantities—berries can stay
- Alcohol—completely during recovery
Frequently asked questions
Will hepatoprotectors help?
There is no evidence that they remove fat. What removes it is avoiding fructose. Spend the money on tests in 3 months.
Is dietary fat harmful to the liver?
No. Dietary fat does not accumulate in the liver. Fructose and excess calories from carbohydrates cause harm.
When should ALT be retested?
After 3 months without sugar and juices. For most people—it is normal. Ultrasound—after 6.
