What happens to a rat's liver on a keto-like diet?
LIVER METABOLIC EFFECTS OF A HIGH-FAT LOW- CARBOHYDRATE DIET IN RATS: A STUDY UNDER DIFFERENT ENERGY CONDITIONS
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Rats ate a diet very high in fat and very low in carbs for four weeks. Scientists checked their liver and blood sugar to see how it changed.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Your liver makes its own sugar when you don’t eat carbs for a long time, and this process doesn’t hurt your liver or cause damage.
When rats eat a diet high in fat and low in carbs, their livers start making more sugar from lactate but get worse at breaking down an amino acid called alanine — especially if they're also eating fewer calories.
Rats on a very low-carb, high-fat diet for a month ended up with higher blood sugar and more fat in their livers—even if they didn’t eat more calories. This kind of diet might not be great for liver and blood sugar health in animals.
In rats, eating a high-fat, low-carb diet makes their bodies worse at handling sugar—even when calories are the same or higher—but doesn’t change how sensitive they are to insulin. This suggests the sugar problem might not be caused by insulin issues in these animals.
Even when rats eat fewer calories, a keto-like diet can still cause unhealthy changes in the liver, like making too much sugar and having trouble breaking down proteins.
