The Claim
Obese adults exhibit a significantly lower thermogenic response to a mixed meal than lean adults, with a 12.9% ± 2.3% increase in metabolic rate compared to a 25.0% ± 4.8% increase in lean individuals, indicating a generalized reduction in postprandial energy expenditure after eating.
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.
After eating a mixed meal, adults with obesity have a smaller increase in metabolic rate than adults with normal weight, resulting in less energy being burned after the meal.
See the scientific wording
Obese adults show a significantly lower thermogenic response to a mixed meal compared to lean adults, with a 12.9% ± 2.3% increase in metabolic rate versus 25.0% ± 4.8% in lean individuals, indicating a generalized reduction in postprandial energy expenditure after eating.
After eating, fat and other nutrients normally trigger the nervous system to activate heat-producing processes in fat and muscle tissues, but in obese individuals, this signal is weaker, so less heat is made and less energy is burned.
What the research says
1 studyStudy: Thermic effect of feeding carbohydrate, fat, protein and mixed meal in lean and obese subjects.
After eating a meal with carbs, fat, and protein, obese people burn about half as much extra energy as lean people, and this study directly measured that difference — obese people burned 13% more energy, while lean people burned 25% more.
