Affectionately referring to dieters as ""chubs,"" this guide doesn't lie about basics: ""You can't eat everything you want"" and. . .""you'll be hungry."" The four food groups and watching calories constitute the approach. Bringing no expertise other than having been in the chub sorority, Lukes nonetheless has solid suggestions and insights: set realistic goals; break weight-loss goals into 5 lb. units. Along with sample diets and true-false tests, readers are treated to humor that may offend: chapters with titles like ""50 ways to lose your blubber,"" and a true-false poser starting, ""Anorexia nervosa is a country in Southeast Asia."" The two-paragraph response is total coverage of this important, unfunny subject. Lukes has a single-cause ""theory"" (societal pressure to be thin) for the complex phenomenon of obesity. Valuable information, but requires a readiness to laugh at oneself.
