Yuan Xiaojuan, a 34-year-old gourmet who died of gastric cancer a few years ago, also summed up the reasons for her physical damage: "I did not treat my stomach well. My diet was extremely irregular, I would eat every meal when I was hungry, and I often went on a diet to lose weight. After repeated tossing like this, the stomach becomes the weakest part of the body."
