The Claim
In healthy overweight men, an isocaloric high-fructose diet (25% energy) resulted in a greater increase in homeostasis model assessment of insulin resistance (0.8 ± 0.9) compared to a high-glucose diet (0.1 ± 0.7), with a statistically significant difference (P = .03).
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.
In healthy overweight men, consuming a diet where 25% of calories came from fructose increased insulin resistance more than a diet with the same number of calories from glucose.
See the scientific wording
In healthy overweight men, a high-fructose diet (25% energy) increased homeostasis model assessment of insulin resistance by 0.8 ± 0.9 during the isocaloric period, while a high-glucose diet increased it by only 0.1 ± 0.7 (P = .03), indicating a potential differential effect on insulin sensitivity.
When the liver processes large amounts of fructose, it turns the sugar into fat, which builds up inside liver cells. This fat interferes with the insulin signal, so the liver stops responding to insulin and keeps making glucose even when it shouldn't.
What the research says
1 studyIn a study where overweight men ate either a lot of fructose or a lot of glucose for two weeks without gaining weight, only the fructose group got more insulin resistant—meaning their bodies had a harder time using insulin properly. This suggests fructose might be worse than glucose for insulin health, even when calories are the same.
