Carbohydrates, including starch, are not effective in creating long-tern satiety.

The satiety after a few hours since a meal is mainly determined by the amount of proteins and of fat contained in it, not by the amount of calories.

For instance, after a meal including 50 g of proteins and 50 g of fat, most people would not be hungry for at least a half of day, or even for an entire day.

If you remove from your 1000 kcal loaf of bread 500 kcal of starch, which can be done by washing the dough before baking the bread, and you eat the result (i.e. a bread greatly enriched in proteins) together with 50 mL (46 g) of olive oil, you will eat less calories, but you will be satiated for many more hours.
