I find it frustrating, too, to see the scale stop or even go UP, when I've stayed on-plan to the LETTER for weeks. In my case, I'm finding that my weight seems to increase more and sooner in my cycle than it did before lc.

I really did have a major stalling/gaining stage for MONTHS between quitting smoking and quitting a physically active job to stay home with my son. Aside from making a conscious effort to exercise (which you seem to be doing already) I tweaked the ratio of fat to protein and carbs, and it's working. For the first time in 6 MONTHS, the scale is moving DOWN again....I eat more fat calories, slightly less protein than before, and went back to induction level on carbs. I also cut out my sugarfree chocolate for now. I still use the shakes and bars a few times a week.

It's frustrating, but you'll eventually hit on a plan that'll get you going if you stick with it!
