Obesity Clinical Trial - Nutrigenomics: Personalizing Weight Loss for

Status Completed

Clinical Trial Summary

This study aims to determine if providing genomic information to veterans can help them lose weight compared to usual care.

Clinical Trial Description

About 35% of veterans are obese. The MOVE! program is a nation-wide 8-week program of group classes nationally to help obese veterans lose weight. While the program is successful for some veterans, about 75% of veterans are unable to lose ≥5% of their weight 24 weeks after MOVE! New methods are needed to help obese veterans seeking weight loss. Using personalized genomic information dictating a specific diet, and information on exercise and eating behaviors, may be one means to help promote weight loss. Just a single nucleotide change or polymorphism (SNP) in a gene can increase a person's risk for obesity, or change their lipid profile in response to the consumption of different macronutrients such as of fats or carbohydrates. Over 54 genetic loci have been associated with obesity phenotypes and clinical studies are now reporting associations between SNPs and/or functional alterations of gene expression (epigenetics) and the ability to lose weight or not. We will implement a randomized clinical trial to test a set of genomic data called the FIT™ test (Pathway Genomics™) containing information on SNPs that affect obesity risk, confer specific diet recommendations, outline eating behaviors and suggest responses to various exercise regimens. The overall goal of this project is to evaluate if this supplemental genetic information with a genomically-derived diet built around packaged meals to improve adherence, in parallel with the MOVE! program at the VA in San Diego, will promote weight loss in more obese veterans than those receiving usual care and eating diets based around packaged meals. Our primary hypotheses are that more obese veterans in the MOVE! program will lose 5% of their weight if they receive personalized genomic information and a genomically-derived diet built around packaged meals when compared to veterans in the same program that receive usual care during MOVE! and packaged meals after 8 or 24 weeks. We also hypothesize that more veterans in the genomic group that lose 5% weight loss at 8 weeks will maintain this weight loss after 24 weeks compared to veterans in the usual care group. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
