When mice with fatty liver disease eat a special high-fat, low-carb diet with certain protein building blocks for a long time, it seems to make their liver problems worse by increasing signs of damage, scar tissue buildup, and fat storage, especially when they haven't eaten for a while.

A special diet with certain proteins made mice with fatty liver disease worse. It caused more fat buildup in their livers, higher levels of a liver damage marker in their blood, and signs of scar tissue forming, which means their liver disease got more serious.

When mice with fatty liver disease eat a special high-fat, low-carb diet with certain amino acids, their livers get better at burning fat, which helps break down extra fat and might improve their condition.

When mice with fatty liver disease eat a special low-carb diet with certain amino acids, their livers make 30-50% less new fat compared to mice eating high-fat food.

When mice with fatty liver disease eat a special low-carb diet with certain protein building blocks, their liver cells produce more harmful oxygen molecules that can cause inflammation and stress in the cells.

When mice with fatty liver disease ate a special low-carb diet with extra amino acids, it didn't help their insulin problems. Their bodies still handled sugar poorly, just like mice on a high-fat diet.
