Is hunger affected by the portion size, or the amount of calories?

Question

For example, if I eat a small steak with 500 calories, will I feel full for longer than if I ate 10 rice cakes with 30 calories each?

Answer 1

Different nutrient sources produce different levels of satiety (the sense of “hey cool I’m satisfied and no longer need to pursue food as much”). Protein reduces your satiety a LOT, whereas carbohydrates reduce your satiety the least. This is why you can eat 800 calories worth of roast chicken or turkey and sit back satisfied (maybe even a little sick of it), but down 800 calories worth of pasta and still be craving more.
