The theory is that by eating what my body wants, and stopping when I am satisfied, I am less likely to eat more than I need.
This is the "protein leverage" theory, which suggests that all animals eat to reach a critical protein intake. The amount varies between species but studies to date suggest that around 15% of calories from protein is Homo sapiens' preferred intake. However, if you are dieting or stressing your body you need more than that and it might need to go up to 30% of calories from protein to satisfy the body's needs in these situations.
