This study is a 6-month randomized controlled trail of diet modification designed to reduce chronic inflammation and reverse metabolic dysfunction among obese individuals with one or more polyps found at a colonoscopy screening. We also will recruit an at least overweight partner, who lives in the same household. To be eligible, participants will be apparently disease-free, obese AAs or EAs who have self-identified a partner who is at least 9 years, with whom they live and who also is at least overweight. Each index participant will: 1) Be AA or EA by self-report; 2) Be ≤55 years old; 3) Have undergone a colonoscopy screening and found to have ≥1 polyp(s); 4) Be free of co-morbid conditions or other factors that would limit participation in this trial; 5) Have a BMI ≥30kg/m2; 6) Be willing to commit to investing the time and effort required to participate in this trial (i.e., willing to complete all assessments and provide biological samples as specified in the consent); and 7) Have no recent antibiotic use. Their partner needs to: 1) Be at least 9 years old; 2) Live in the same household and consumes meals together; 3) Be at least overweight; 4) Agree to all study procedures, including provision of biological samples, body measurements, and self-reported dietary and other assessments; and 5) Have no recent antibiotic use.
