The 1972 book (yeah, I got it at a book sale) has some anecdotal stories and is rather vague about the eating plan. It gives the impression that you go the first two weeks with no carbs, but it has some remarks about there being virtually no carbs in lettuce so salad is allowed. It is quite vague and has little to no research in it.

Look for the 1992 or newer version, I picked up some from another book sale for friends and family. This will tell all the details and provide research and more anecdotal stories.
