The Claim
A 7-day hypercaloric high-fructose diet reduces hepatic insulin sensitivity in healthy men, as evidenced by decreased suppression of fasting hepatic glucose output during hyperinsulinemic clamps.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating a high-sugar, high-calorie diet for 7 days reduces the liver's ability to respond to insulin in healthy men, leading to higher glucose production even when insulin levels are elevated.
See the scientific wording
A 7-day hypercaloric high-fructose diet decreases hepatic insulin sensitivity in healthy men, as measured by reduced suppression of fasting hepatic glucose output during hyperinsulinemic clamps, indicating impaired liver response to insulin.
When too much fructose enters the liver, it gets turned into fat. This fat builds up inside liver cells and blocks the signal from insulin that tells the liver to stop releasing sugar. As a result, the liver keeps pumping sugar into the blood even when it shouldn't.
What the research says
1 studyEating a lot of fructose for a week made the liver less responsive to insulin, so it kept releasing sugar into the blood even when the body told it to stop. This is exactly what the claim says.
