Eating protein makes your gut release certain hormones that help you feel full faster and eat less food.

Eating more protein makes you feel fuller for longer, so you’re less likely to snack or eat too much later.

When people eat high-protein, low-carb ultra-processed foods, their bodies release more hormones that tell them they’re full (PYY and glucagon) and less of the hunger hormone (ghrelin), which may explain why they eat less.

Eating more protein makes you feel fuller for longer, which can help you eat less overall and avoid gaining weight.
