Low carb worked for me but I was miserable and eventually gave in and gained all the weight back. That was me on Atkins. I felt a lot better on the South Beach diet but plateaued big-time after losing 30lbs. I now am just trying to do what everyone told me to do all along: eat right and get moving. I am losing slowly but I don't deprive myself either.
I am sure if I was strict with my calories and really watched what I ate-I probably would be losing a lot more. I am working on that.
