I must be the only person in the world who gained weight on Atkins, and South Beach, too. I tried both for the induction phase + 1 week, and gained 5 lbs on Atkins, 10 on South beach. Now I'm on WW, and have lost that 15, plus another 10, and I'm NEVER hungry, and NEVER felt the least sick or uncomfortable. Guess there's a method for everyone, and not every method is good for every person.
