Judging from the process of digestion, the main component of potatoes is starch. From the mouth to the esophagus to the stomach and small intestine, these organs have no fat. Potatoes turn into glucose when they reach the small intestine, and then they are absorbed by the capillaries in the wall of the small intestine, with little contact with fat. So, potatoes don't absorb fat! But potatoes are rich in nutrition, and moderate consumption can enhance satiety. Less energy intake is still helpful to lose weight! But the most important thing is to strengthen exercise!

Eating potatoes helps to lose weight, because potatoes feel full after eating, which can make you consume less energy. Coupled with exercise, you can consume body fat, not energy from food! But if you think potatoes can absorb fat and eat more, that's not good. That will only convert the excessive energy into fat and store it.
