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

You can fill up pretty fast eating cellulous noodles in a flavorful broth with no useful food calories at all. (That is, it’s indigestible. It would certainly burn in a calorie test). Trying to eat that instead of food, you’d feel full but sick in pretty short order.

​

As to your example:

The steak will likely make you feel full longer. The meat takes longer to digest opposed to the relatively easy to break down carbohydrates in the rice cakes.
