Few reports exist of weight loss in clinical programs offering increasingly aggressive meal plans. Weight management programs (WMP) that can provide efficacious care to large segments of the population are needed.
PURPOSE: Describe differences in weight change at 3, 6 and 12 months after self-selection of a meal plan and participation in a clinical WMP.
METHODS:A retrospective analysis was performed using prospectively collected longitudinal data of a cohort who participated in a clinical WMP (age= 49 ± 12 years, mean body mass index= 42 ± 8 kg·m-2, weight= 117 ± 26 kg, 80% female, 53% black). Following self-selection of one of three meal plan options [Hypocaloric (HC), Partial (PM) or Complete Meal (CM) Replacement], patients began the program at a visit with a registered dietitian to implement their meal plan. They then met with a clinical exercise physiologist every 2- 4 weeks for counseling which included discussion about their meal plan, exercise routine and associated behaviors. Data collection occurred at program entry, during routine counseling appointments and at physician visits between January 2004 and January 2007. Intent-to-treat analysis and linear mixed modeling were used for data analysis.
RESULTS:Data was available for analysis in 2,316 patients. Weight loss results and meal plan comparisons are shown in the figure. Higher visit attendance was associated with a 3-5 fold increase in weight loss at 12-months.
CONCLUSION: Among patients who enrolled in a clinical WMP, those who self-selected a Complete or Partial Meal Replacement plan lost more weight at 3, 6 and 12 months than those selecting a Hypocaloric plan. And the Complete Meal Replacement plan was more effective at each time point than the Partial Meal Replacement plan.
