The Claim

In mice fed a high-fat diet, supplementation with fructose and glucose similarly increases hepatic ceramide synthesis and upregulates the expression of lipogenic enzymes SREBP-1c and ACC, indicating that both sugars promote hepatic fat accumulation through shared metabolic pathways.

How it works
1 study reviewed
In plain English

In mice eating a high-fat diet, adding fructose or glucose to their food increases the production of fat-related molecules in the liver and activates genes that drive fat storage, leading to greater fat accumulation in the liver.

See the scientific wording

In mice on a high-fat diet, fructose and glucose supplementation similarly increase hepatic ceramide synthesis and expression of lipogenic enzymes (SREBP-1c, ACC), suggesting that both sugars promote fat accumulation in the liver through overlapping metabolic pathways.

Why this might work

When mice eat a high-fat diet and extra sugar, their liver gets flooded with fatty acids and sugar molecules. These trigger the liver to make more harmful fats called ceramides, which block the liver’s ability to burn fat for energy. At the same time, the liver starts making more enzymes that turn sugar into new fat. The buildup of ceramides and fat overwhelms the liver, causing damage and inflammation that worsens fat storage.

  1. Study: No Difference in Liver Damage Induced by Isocaloric Fructose or Glucose in Mice with a High-Fat Diet

    In mice eating a high-fat diet, adding either fructose or glucose led to the same amount of fat-building molecules and harmful fats in the liver — meaning both sugars work in similar ways to make liver fat worse.
