You can eat egg yolk during weight loss. Egg yolk is very rich in egg yolk protein, but not high in calories. After intake, it can replenish abundant energy for the body's metabolism, but it will not cause fat accumulation and obesity. Don't worry too much about this situation. Moreover, eating egg yolk during weight loss will increase satiety and reduce the intake of other staple foods. However, it should be noted that if people with cholecystitis lose weight, it is best not to eat egg yolk, otherwise it may lead to gallbladder pain.
