Hello, you won't get fat. Everyone needs to supplement 2000 calories a day on average. The calories of two apples are about 200, that of a boiled egg is about 70, that of a kilo of pitaya is about 250, that of a cucumber is about 40, and that of milk oatmeal is about 180, which is ***740 calories in total, far below the daily needs of human body! I hope you can adopt.
