Macro partitioning
Lowering dietary protein from 15% to 10% of energy intake causes a significant increase in total energy consumption (overconsumption) in lean humans, whereas increasing protein to 25% does not reduce energy intake.
If you want to control your total calorie intake, ensure your diet has a moderate to high protein content (around 15-25% of calories). Dropping protein too low (e.g., 10%) will likely cause you to eat significantly more calories, even if the food tastes the same. However, simply adding more protein than usual may not automatically make you eat less, especially if you have constant access to a wide variety of foods.
Lowering the percent protein of the diet from 15% to 10% resulted in higher (+1264.5%, p = 0.02) total energy intake... In contrast, increasing protein from 15% to 25% did not alter energy intake.
Why this rating
Randomized controlled trial with disguised macronutrients, but short duration (4 days) and small sample size (n=22).
