The Claim
Human food intake is regulated by a fixed daily protein target, and hunger persists until that target is met regardless of total caloric intake.
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.
Human eating behavior is controlled by a set daily amount of protein needed, and feelings of hunger continue until that protein amount is consumed, even if enough calories have been eaten.

What the research says
2 studiesStudy: Testing Protein Leverage in Lean Humans: A Randomised Controlled Experimental Study
When people eat food with less protein, they feel hungrier and end up eating more calories trying to get enough protein — even if they’re already full from other foods. This suggests the body is driven to hit a protein target, no matter how many total calories are eaten.
Study: Protein appetite as an integrator in the obesity system: the protein leverage hypothesis
People’s bodies are wired to get enough protein, and if their food doesn’t have much protein, they keep eating until they’ve had enough—even if they’re already full of calories. That’s why junk food can make you overeat.
