Study 1 compared overweight adult women smokers (n = 50) and nonsmokers (n = 50) in an hypnosis-based, weight-loss program. Smokers and nonsmokers achieved significant weight losses and decreases in Body Mass Index. Study 2 treated 100 women either in an hypnosis only (n = 50) or an overt aversion and hypnosis (n = 50) program. This multicomponent follow-up study replicated significant weight losses and declines in Body Mass Index. The overt aversion and hypnosis program yielded significantly lower posttreatment weights and a greater average number of pounds lost.
