Outcomes of a traditional weight control program and a nondiet alternative: a one-year comparison.
The purpose of this study was to evaluate the effectiveness of a traditional weight control program and nondiet alternative in improving behavioral (e.g., restrained, emotional, and external eating), psychological (e.g., body preoccupation, physical self-esteem), and biomedical (e.g., body weight, blood pressure, cholesterol) outcomes. There were 2 intervention groups--traditional weight control (TWC) and Diet Free Forever (DFF); a nonvolunteer comparison group; and a control group, all made up of employees of 3M (N = 357). The 2 intervention groups participated in 10-week eating programs. Outcome variables were assessed at baseline, at 10 weeks for the intervention groups only, and again at 1 year. At baseline, the 2 intervention groups had higher restrained, external, and emotional eating scores, greater body preoccupation, and lower physical self-esteem than the comparison and control groups. They also weighed more. At 1 year, both intervention groups had decreased their body preoccupation and increased their physical self-esteem. Participants in the DFF program reduced their restrained eating, whereas those in the TWC program increased their restrained eating. Neither eating program had an impact on the biomedical outcomes.
