I want to come off atkins, i lost all the weight i wanted. tips?

i do not want to lose any more weight whatsoever using atkins. i have been on it for almost two years and would like to healthily stay at my current weight. i am aware that i will not be able to dig into a huge pasta bowl or chocolate cake and expect myself to remain at this weight. but how can i remain at this weight with a very conscious eye about what i eat. i have just lost 4 lbs after having a 3 month plateau of no weight loss at all. and i want this to be the beginning of my healthier lifestyle.
