The Claim
In obese and lean women, ingestion of 75 grams of fructose increases cumulative carbohydrate oxidation by 25% over six hours compared to ingestion of 75 grams of glucose, with mean oxidation rates of 51.1 g and 40.9 g, respectively.
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.
When obese and lean women consume 75 grams of fructose, their bodies oxidize 25% more carbohydrates over six hours than when they consume 75 grams of glucose, with average oxidation rates of 51.1 grams versus 40.9 grams.

When fructose is eaten, the liver processes it quickly and turns it into lactate, which enters the bloodstream. Other tissues like muscle and the heart take up this lactate and burn it for energy, using more oxygen and producing more heat. This forces the body to burn more carbohydrates overall compared to when glucose is eaten.
What the research says
1 studyStudy: Thermogenesis in obese women: effect of fructose vs. glucose added to a meal.
When people ate 75 grams of fructose, their bodies burned about 10 grams more carbs as fuel in six hours than when they ate 75 grams of glucose — so fructose made their bodies use more carbs for energy.
