From my experience it sounds like you're consuming a little too many carbs. I'm not an advocate of the Atkins diet but my wife is trying the South Beach diet and she's having some good results. She's not into working out but I am and I tried switching from a diet with a higher concentration of calories coming from carbs to a diet containing more proteins and I lost about 5 pounds. Give that a try. I'm definitely NOT a fan of the low or no carb diet. Please don't misunderstand my comments!
