The Claim

In adults with mild type 2 diabetes, a 12-week ketogenic diet is associated with a 50% increase in acute C-peptide response to glucose, and this increase is inversely correlated with reductions in liver fat and pyruvate levels.

How it works
1 study reviewed
In plain English

In adults with mild type 2 diabetes, following a ketogenic diet for 12 weeks is linked to a 50% higher C-peptide response after glucose intake, and this is accompanied by lower levels of liver fat and pyruvate.

See the scientific wording

In adults with mild type 2 diabetes, a 12-week ketogenic diet is associated with a 50% increase in acute C-peptide response to glucose, indicating improved beta-cell function, which is inversely correlated with reductions in liver fat and pyruvate levels.

Why this might work

When sugar intake drops, the liver stops making fat and starts burning fat for energy. This lowers fat buildup in the liver and reduces a molecule called pyruvate. With less pyruvate, the liver shifts energy production toward making ketones instead of fat. The drop in liver fat means fewer fatty acids spill into the bloodstream and reach the pancreas. This removes toxic fat buildup in insulin-producing cells, allowing them to respond properly to sugar by releasing more insulin.

  1. Study: Beneficial Effects of Carbohydrate Restriction in Type 2 Diabetes Can Be Traced to Changes in Hepatic Metabolism

    This study found that adults with mild diabetes who ate a very low-carb diet for 12 weeks had better insulin production after eating sugar, and this was linked to less fat and less pyruvate in their liver — exactly what the claim says.
