Unbelievable~! Of course you will gain the weight back if you go back to the way you were eating before! I know I would also gain it back eating all that pasta, rice and crap I was consuming before! Still people see Atkins or any LC plan as a "quick diet" and not a life-time commitment. That is where the problems arise. I tell people that this is FOR LIFE...thus I never plan on gaining the weight back. They quickly shut up.
