The Claim

In female rats consuming 13% (w/v) HFCS-55 for 8 weeks, hepatic fatty acid oxidation is reduced compared to sucrose consumption, as evidenced by down-regulation of peroxisome proliferator-activated receptor α, indicating impaired liver fat burning capacity leads to lipid accumulation.

Source: High-fructose corn syrup-55 consumption alters hepatic lipid metabolism and promotes triglyceride accumulation.

How it works
1 study reviewed
In plain English

Female rats fed a diet with 13% high-fructose corn syrup for 8 weeks showed lower rates of fat burning in the liver and increased fat buildup compared to rats fed sucrose, linked to reduced activity of a key regulatory protein.

See the scientific wording

In female rats consuming 13% (w/v) HFCS-55 for 8 weeks, hepatic fatty acid oxidation was reduced compared to sucrose, as indicated by down-regulation of peroxisome proliferator-activated receptor α, suggesting impaired fat burning capacity in the liver contributes to lipid accumulation.

Why this might work

Fructose from HFCS-55 floods the liver, turning on fat-making genes and turning off fat-burning genes. The liver makes more fat from sugar, stops breaking down existing fat, and fails to ship fat out of the cell. Fat builds up inside liver cells because it is made faster than it is burned or removed.

1 study
  1. Study: High-fructose corn syrup-55 consumption alters hepatic lipid metabolism and promotes triglyceride accumulation.

    Rats that drank a sugary drink with high-fructose corn syrup burned less fat in their livers than rats that drank regular sugar, even when they ate the same amount. This caused more fat to build up in their livers.
