What diet plan are you using?

Are you using an Ultra Low Carb plan like Atkins or the Zone Diet, or something a little less strict like South Beach. What about the Biggest Loser Diet plan? I have been using the South Beach plan for awhile along with some elements of Biggest Loser. A few variations that I am doing: I love milk so I do allow myself to have skim milk on occasion. I also eat an apple and cheese stick quite frequently as a snack. If I feel like I am going into a stall, I will also cut back to around 30-35 carbs/day for a few days and that usually breaks my stall. Anyone else using a similar plan?
