Is there a big difference between losing weight and not losing weight?

I live abroad, so I've gained a lot of weight...hahahahaha; I'm kind of big, geez...ㅎㅎㅎ When I was trying to get my eyes and nose done , people all told me to lose weight first because if I gain weight later, it might not suit my image. Especially when I lose weight, my cheeks are gone and my chin is really pointy (only the front, the sides are geez...) My face isn't that wide, but somehow I suddenly gained a lot of weight and didn't lose it, so now it's round... very flat; My image is also kind of dull geez... I'm going to go on a diet when I go, but I'm determined to lose about 10kg. Will it not suit me later on? If I really lose weight, I'll gain a lot of weight; I love you, Sungye Society members -_-* Heung <- I don't know why I'm doing it geez...;;;;;;;
