Atkins Diet, has anyone had any success?

Has anyone tried the Atkins Diet with great success! I have a pouchie belly to loose by June perhaps 15lbs. I heard the Atkins Diet is great to eliminate fat fast. I go to the gym 4 days a week, 1200 calorie diet so, I'm not lazy and definitely can't afford to eat any less! Any Suggestions about the Atkins Diet or what has worked for you?
