Potato is a carbohydrate food, which can be used as a staple food. The carbohydrate content in potato (17 g/ 100 g) is about a quarter of that of rice with the same weight, which means the starch content is much less. Starch in potatoes is a kind of resistant starch, which is much more than that in rice, and its digestion and absorption are also slow. It moves slowly in the whole intestine, which can increase satiety and help take away some oil. In addition, the fat content in potatoes is extremely low, accounting for only 0. 1% ~ 0.2%, which is basically negligible. So using it instead of some rice certainly has the effect of losing weight.
But be careful not to eat too much, and don't put too much oil when frying shredded potatoes, otherwise it will be bad for losing weight.
