When kids or grown-ups eat too much sugar and carbs, their liver can get fat and sick. This study shows that when people with fatty liver stop eating carbs for just two weeks, their liver gets healthier very quickly.
Surprising Findings
Liver fat dropped dramatically without calorie restriction or significant weight loss.
Most assume fat loss requires calorie deficits; this shows macronutrient composition alone can drive rapid organ-level change.
Practical Takeaways
Try a 2-week low-carb, high-protein reset (under medical supervision) if you have fatty liver.

If you're an obese adult with fatty liver disease, switching to a low-carb, higher-protein diet for just two weeks might quickly boost good gut bacteria that make folate—and your blood folate levels could go up in as little as one day.
If you're an obese adult with fatty liver, going on a low-carb diet for just two weeks—even without cutting calories—might slash your liver's fat production by nearly 80% and boost fat burning in your body by almost 5 times.
Eating fewer carbs and more protein for a week might help turn off fat-making genes and turn on fat-burning and metabolism genes in the livers of obese people with fatty liver disease.
Eating too many carbs and calories — especially from sugary or processed foods — is what mainly causes fatty liver, not eating fat. Cutting out carbs or going on a carnivore diet might help reverse it.
If you're an obese adult with fatty liver disease, switching to a very low-carb, high-fat diet for just two weeks might cut your liver fat by nearly half—and you could see improvements in as little as one day.
