every time you treat LC as a diet--go off and back on--it will work less well. Very young people and men will notice little effect; women and those over 40 will notice this a lot!

One little bit twice a week can keep you out of ketosis in the OWL phase.

The most efficient thing to do is to re-read the book, return to following the plan (but nix the bars/shakes/artificial sweeteners). Then take whatever loss rate you get with gratitude and relief that you can still lose at all. This is what I've done.

Also, you may want to re-think your goal weight. If your body keeps balancing out to 150, that might be your natural, healthy weight.

HTH!
