According to the book - when you get closer to your goal, you MSUT move on. IT is important to follow through ALL the stagfes of atkins in order to reach lifetime maintenance.

I would suggest you move on to the next stage and change your exercise.

Those loose bits may not be fat, but untoned muscle.
Start weight training and something like pilates to tone up rather than loose more weight.


And no, you will not lose 1 lb a week forever, it will eventually slow and stop whne your body decideds it's at a healthy weight.
