Hi, Mark91345 and Kathleen24. Thanks for the comments.

Regarding drop-out rates:

Successful weight loss and long-term management is a little like quitting cigarettes. Most successful quitters have tried 6-8 different times and mutliple methods before finding what works for them. Or perhaps something happens that finally triggers full commitment, like a diagnosis of lung cancer in a smoking relative.

And American culture could do a lot more to make low-carbing easier.
