The Claim
In obese and lean women, a single meal containing 75 grams of fructose as the carbohydrate source increases postprandial thermogenesis by approximately 10.2% of meal energy content, compared to 8.4% with 75 grams of glucose.
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 eat a meal with 75 grams of fructose, their bodies burn 10.2% of the meal's energy as heat after eating, which is higher than the 8.4% burned after eating 75 grams of glucose.
See the scientific wording
In obese and lean women, a single meal containing 75 grams of fructose as the carbohydrate source increases postprandial thermogenesis by approximately 10.2% of meal energy content, compared to 8.4% with 75 grams of glucose, suggesting fructose may enhance short-term energy expenditure after eating.
When fructose is eaten, the liver processes it quickly and uses up a lot of energy in the process. This causes a temporary energy shortage in liver cells, which triggers the production of lactate. The lactate then travels to other tissues like muscle and heart, where they burn it for fuel, using extra energy and releasing heat. This whole process makes the body burn more calories as heat after eating fructose compared to glucose.
What the research says
1 studyStudy: Thermogenesis in obese women: effect of fructose vs. glucose added to a meal.
When people ate a meal with fructose instead of glucose, their bodies burned a little more of the meal’s energy as heat — about 10.2% vs. 8.4% — and this happened the same way whether they were lean or obese.
