I agree that our bodies have a set point. For the longest time my set point was 206. I would lose a bit, but as soon as I wavered I was back to 206. I wanted to get and stay below 200. Finally, I did it. I have been fluctuating in the 190s now for about a month. Up a few, down a few, but never going back over 200 or getting down into the 180s. But I know if I persevere I will do it. I don't eat sweets or junk food, but my meals are not Atkins-like low carb, just much lower carb than they used to be. Hopefully my new set-point will be in the 180s.
