살이 찌고 싶다!

I was losing my appetite due to gastric flu the past week. It was horrible! At the smell of food, I felt like vomitting although I was very hungry. I used to finish my food very quickly but now I can barely finish it.

Though now I have regained my appetite, I still can't finish my food as quickly as before. Also, I lost weight! I'm only 46 now... How can I gain 4 more kilos?

살이 잘 찌는 사람은 어떻게 해야하죠??
