The Claim
Gastric emptying rates for glucose and fatty meals are not delayed in obese adults compared to lean individuals, and this absence of delay suggests that the reduced thermogenic response to fat is not attributable to slower digestion or absorption.
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.
Obese adults digest glucose and fatty meals at the same rate as lean individuals, and the lower heat production from fat in obese people is not caused by slower digestion or absorption.
See the scientific wording
Gastric emptying rates for glucose and fatty meals are not delayed in obese adults compared to lean individuals, suggesting that the reduced thermogenic response to fat is not due to slower digestion or absorption.
After eating fat, the nervous system does not activate fat-burning tissues as strongly in obese individuals, so those tissues produce less heat and burn fewer calories, even though the fat is absorbed at the same rate as in lean individuals.
What the research says
1 studyStudy: Thermic effect of feeding carbohydrate, fat, protein and mixed meal in lean and obese subjects.
Obese and lean people digest sugar and fat at the same speed, but obese people don’t burn as much energy after eating fat — so it’s not because the food stays in their stomach longer; it’s something else about how their bodies use fat.
