That's because it takes a lot longer for protein to digest than carbs, which means you can eat less food and still feel satisfied for the same amount of time (if not longer), Brian St. Pierre, director of performance nutrition at Precision Nutrition, tells BuzzFeed Health.

Protein is also ~kind of~ necessary for certain things. It helps our muscles recover from a workout; it helps us build muscle, which is great if you're trying to lose weight; and it won't spike your blood sugar levels the way a carb-heavy meal would.
