Good for you - glad you found your way! I think that 'stalls' can be helped by tweaking of calories, or upping exercise without upping calories. A calorie is a calorie, but if you want the metabolic advantage to work, you've got to give it a chance to create a little deficit.

I did the Zone a few years back and lost a lot of weight, but then stalled out, because my calories were at a level that would maintain my weight, not drop it. Atkins is giving me the lack of hungries that is allowing me to take in fewer calories than before...
