Protein can help you feel fuller
The American Journal of Clinical Nutrition. 2008 / PMID 18469287
Protein is not magic, and its effect on fullness varies from person to person.
Protein and recomp drop
Protein can help with fullness, recovery, and lean-mass retention during fat loss or recomposition, but it still works alongside training and total calories.

Related questions
Protein and hunger answer
Protein can help many people feel fuller and make a fat-loss plan easier to repeat, but it is not a hunger off-switch. Use it as a meal anchor that protects lean mass and reduces the odds of random grazing.
Protein and recomp answer
Protein is one of the most reliable supports for body recomposition, but it is not magic by itself. Training creates the adaptation signal; protein helps support satiety, recovery, and lean-mass retention while calories are managed.
