If i went back to my normal lifestyle will i lose the weight ?

I live in the US but i came to my parents for a visit. I'm visiting them for a week and a half and all i can think of are the sweets and food infront of me. Their so good and i don't see that much sweets or even buy sweets in america because i know i'll eat them all. So the problem is i binged like 5 times since i got here. I can feel my body stretching and telling me to stop eating so much !! but i couldnt help it. I gained like 4 or 5 kgs now. I don't know if i'll lose them when i get back to my old life style or if it will not go away? Can you please help me. Thanks
