The 24 hour come-on means simply that you take the psychological hurdles one day at a time, like the quit smoking or AA regimens. The author offers a step-by-step process with a generally uncritical selection of reducing systems, from calorie counting to a cottage cheese and diet soda project.

The recipes are reasonably interesting, but chemophobes will not like Small's ringing endorsement of certain ""ready foods"" -- he extols ersatz marvels like D-Zerta. In fact there is more emphasis here on attrition than nutrition. The diet-day boosters may be helpful to new recruits, but for the whole picture Trager (p. 1087) is safer, better.
