Obesity Clinical Trial
Official title:
A Randomized Trial Comparing Two Doses of Portion-Controlled Foods Within a Primary Care Weight Loss Program
We hypothesize that individuals provided with 1 meal per day of portion-controlled foods (shakes and prepared entrees) will lose as much weight as individuals provided with 2 meals per day of portion-controlled foods. The study is designed to assess whether equal weight loss can be achieved at a lower cost to the health care system (or health care payer), with patients contributing some of the cost of their own treatment.
The study has two goals. First, it will assess the efficacy of a weight loss program, using a combination of counseling by peer weight coaches and portion-controlled foods. Second, the study will test the effect of varying the "dose" of portion-controlled foods provided to patients by randomly assigning individuals to receive half or all of the food required to follow a meal replacement regimen. The primary endpoint of the study will be weight change. Secondary endpoints will include adherence to the recommended eating plan, health-related quality of life, as well as changes in waist circumference and blood pressure. The provision of "half-dose" portion-controlled foods (1 meal per day) is hypothesized to be non-inferior to provision of "full-dose" (2 meals per day). The goal of non-inferiority is important because it can demonstrate that health care payers wishing to support weight loss programs can achieve equivalent results at a lower cost. All patients have the choice regarding their use of portion-controlled foods in the study, and no patients will be asked to leave the study because of non-adherence. ;
