The Claim
Does protein burn more calories after eating than carbs or fat?
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.
Eating protein makes your body burn more calories after eating than eating the same amount of carbs or fat, no matter if you're lean or obese.
See the scientific wording
Protein meals are associated with a greater and more prolonged thermic response compared to isoenergetic carbohydrate or fat meals in both lean and obese adults, suggesting macronutrient composition influences postprandial energy expenditure regardless of body weight status.
What the research says
1 studyStudy: Thermic response to isoenergetic protein, carbohydrate or fat meals in lean and obese subjects.
Scientists gave people meals with the same calories but different main ingredients—protein, carbs, or fat—and found that protein made the body burn more energy for longer, no matter if the person was lean or obese.
