Short answer : the link between protein and satiety is well established: at equal calories, protein fills you up more than carbs or fat, so you can eat less without feeling hungry.
Why protein is so filling
Digesting protein takes more energy and affects appetite hormones, including those that tell your brain you are full. It also slows stomach emptying, which prolongs the feeling of fullness.
How much to eat at each meal
A handy rule: 20 to 30 g of protein per meal, spread through the day rather than almost all at dinner. A protein-rich breakfast often reduces mid-morning cravings.
Filling meal examples
- Plain Greek yogurt, nuts and berries at breakfast
- Chicken, vegetables and quinoa at lunch
- A low-sugar protein bar as a snack
- Fish, green vegetables and olive oil at dinner
What works against fullness
Highly refined meals (white bread, sweets, juice) give a short energy boost followed by quick hunger. Always pair carbs with a protein source.
