I heard that after stopping atkins and maintaining yourself, you gain weight in different places is this true?

My roommate from college did atkins and lost a lot of weight, she stopped, and now shes saying shes gaining weight back in weird places. or different places. she's scarring me because i have been doing a low carb diet for a while now, and wanted to start a more low cal type of thing. can fat really get misplaced? i never had a big belly or anything, is it possible that any weight gain will go there first?
