TL;DR
Data obtained after 55 weeks of treatment showed that the program seemed quite effective for 65% of those who participated for at least 12 weeks, and correlational analyses showed that binge eating, high levels of psychological distress, and low income levels were associated with poorer outcomes.
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.
