ABSTRACT
This study evaluated the effectiveness of a comprehensive obesity treatment program which incorporated open-ended treatment duration, pre-treatment assessments, protein-sparing modified fasts (PSMFs), and the use of six a priori outcome categories to analyse outcomes. Subjects were the first 291 obese individuals (mean weight = 235 lb, 66% overweight) to participate in the program's intake procedures. Data obtained after 55 weeks of treatment (on average) showed that the program seemed quite effective for 65% of those who participated for at least 12 weeks (mean = 62 and 30 lb lost in the two successful groups). Analyses supported the continued use of pre-treatment assessments, extended treatment times, and a priori categorizations of outcomes. In addition, correlational analyses showed that binge eating, high levels of psychological distress, and low income levels were associated with poorer outcomes.
