Postprandial Thermogenesis Is Increased 100% on a High-Protein, Low-Fat Diet versus a High-Carbohydrate, Low-Fat Diet in Healthy, Young Women

Randomized Controlled Trial

Human

2002 Feb

The study gave women two different diets—one with lots of protein and one with lots of carbs—and found that their blood showed more urea nitrogen after the high-protein diet, which means their bodies were breaking down more protein, just like the claim says.

When people eat more protein and fewer carbs, their bodies hold onto more protein instead of breaking it down and losing it, which means they’re building or maintaining muscle better.
