Preference and Vegetarian Diet in Weight Loss Treatment - Full Text View

Sponsors and Collaborators:	University of Pittsburgh National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)
Information provided by:	University of Pittsburgh
ClinicalTrials.gov Identifier:	NCT00330629

Purpose

We propose to add a treatment preference component to a larger study testing standard behavioral treatment (SBT) for weight loss without specific food group restriction vs standard behavioral treatment with gradual elimination of meat, poultry, and fish [a lacto-ovo-vegetarian (LOV) meal plan].

Eligible respondents will be randomized to one of two conditions: Treatment Preference-Yes/No. Individuals in the Treatment Preference-Yes will be assigned to their choice (SBT or SBT+LOV), those in Treatment Preference-No will be randomized to either SBT or SBT+LOV without regard to their preference.
