The Claim
Reducing dietary protein percentage from 15% to 10% of total energy intake in humans leads to a 12% increase in ad libitum energy consumption, with protein intake held constant, indicating that protein appetite drives compensatory overeating when protein is diluted by carbohydrates and fats.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When the proportion of protein in the diet is lowered from 15% to 10% of total calories, people tend to eat more total food to maintain their protein intake, resulting in higher overall energy consumption.
See the scientific wording
In humans, reducing dietary protein percentage from 15% to 10% of total energy intake leads to a 12% increase in ad libitum energy consumption, while protein intake remains stable, suggesting that protein appetite drives compensatory overeating when protein is diluted by carbohydrates and fats.
What the research says
1 studyStudy: Protein appetite as an integrator in the obesity system: the protein leverage hypothesis
When there's less protein in your food, your body tries to get enough by making you eat more overall — even if you're not hungry. This study shows that’s why people might eat too many calories when their food is full of carbs and fats but low in protein.
