The Claim

In male C57BL/6 mice, a diet containing 34% fructose increases hepatic expression of SREBP-1c and PPAR-γ and decreases hepatic expression of PPAR-α, resulting in a shift from fatty acid oxidation to lipogenesis and contributing to the development of nonalcoholic fatty liver disease.

How it works
1 study reviewed
In plain English

In male C57BL/6 mice, a diet with 34% fructose increases the activity of genes that promote fat production in the liver and decreases the activity of genes that break down fat, leading to fat accumulation in the liver.

See the scientific wording

In male C57BL/6 mice, a diet with 34% fructose increases hepatic expression of SREBP-1c and PPAR-γ while decreasing PPAR-α, leading to a shift toward lipogenesis and away from fatty acid oxidation, contributing to nonalcoholic fatty liver disease.

Why this might work

When the liver processes large amounts of fructose, it produces excess fat-building blocks and shuts down fat-burning machinery, causing fat to pile up in liver cells. This happens because fructose turns on genes that make fat and turns off genes that burn fat, leading to fatty liver disease.

What the research says

1 study
  1. Study: Hepatic Adverse Effects of Fructose Consumption Independent of Overweight/Obesity

    In mice, eating a lot of fructose makes the liver start making more fat and stop burning fat, even if the mice don’t get heavier—this causes fat to build up in the liver.
