Why protein makes you burn more calories after eating
Thermic response to isoenergetic protein, carbohydrate or fat meals in lean and obese subjects.

Surprising Findings
Obese individuals had higher post-meal glucose spikes and fasting insulin, yet exogenous glucose oxidation rates were identical to lean individuals.
Everyone assumes obesity = broken glucose metabolism, but this study proves cells use dietary sugar just as efficiently—meaning the problem is insulin overproduction, not cellular failure.
Practical Takeaways
Replace one carb-heavy meal per day with a high-protein meal (e.g., eggs, chicken, tofu) to boost post-meal calorie burn by 2-3x.

Diet-induced thermogenesis is significantly higher for dietary protein compared to carbohydrates and fats due to the greater metabolic cost of protein absorption, transport, and amino acid metabolism.
People with obesity tend to have higher insulin levels when fasting and their blood sugar spikes more after eating carbs, but their bodies still use the sugar from those carbs just like lean people do.
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.
Obese and lean people burn about the same number of extra calories after eating the same amount of food, no matter if it’s protein, carbs, or fat.
Even though obese people have higher blood sugar after eating carbs, their bodies still break down and use the sugar from those carbs just as well as lean people do.
