Potatoes contain resistant starch, which helps to lose weight. Potatoes contain a kind of starch that is not digested by amylase, just like dietary fiber, which can give people a feeling of fullness. This kind of starch is called "resistant starch". However, this resistant starch can be digested and absorbed once it is heated and cooked, so if you want to eat potatoes to lose weight, you can wait until the cooked potatoes are cooled, which can produce enough satiety, reduce energy intake, and then control weight gain.
