Participants were encouraged to continue self-monitoring their intake for 1 week every month during maintenance. If participants were succeeding at weight loss maintenance, self-monitoring was encouraged but not as strongly emphasized. To simplify self-monitoring and encourage adherence to the calorie and fat goals, structured meal plans and meal-replacement products were provided as an option for participants. Participants also continued to self-monitor their activity using either the daily “Keeping Track” booklet or a monthly calendar.
