The authors
Why we write these
The science already exists. It should not take a medical degree to use it.
Between us we have spent our careers on either side of the same gap: one in the operating theatre and the laboratory, one in medical data science and university teaching. The gap is the same in both places. The evidence needed to answer an ordinary question about your own body usually exists, and it is written for people with a decade of training, priced behind a paywall, and summarised in the press by someone who read the abstract.
So the series has one rule: cite the research itself, never another popular book, and print the caveat next to the number. Sixty-six days is a median, not a promise; the range is 18 to 254 days, and the workbook says so on the back cover. That is the whole editorial policy.
The other half is form. A guide is written to be read through and returned to. A workbook is written to be filled in: five by eight inches so it travels, one page a day so it takes three minutes, and a floor for the days when the full version was never going to happen. Books that get used look different from books that get admired.

A necessary note
These books are educational. They are not medical advice, they cannot know your history, and they are not a substitute for a clinician who does. Where a book suggests raising something with your doctor, that is the recommendation, not a hedge.
