Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to determine the association between genotypes and diet. The weight and weight loss data are already available from the previously completed study called: A to Z Study - Benefits and Risks of Alternative Weight Loss Strategies - A Clinical Trial, which was performed from 2003-2005 at Stanford University. In the present study, Interleukin Genetics will obtain DNA samples from the previously enrolled study subjects to investigate genetic influence of the response to macronutrient compositions of low caloric diets to weight loss.
