Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Overweight/obesity will be defined by body mass index (overweight 25-29.9 kg/m2 or obesity 30 kg/m2 or greater). Exclusion Criteria: * Probable familial hypercholesterolemia, defined by: total cholesterol greater than 290 mg/dL or LDL levels greater than 190 mg/dL plus a family history of myocardial infarction (MI) before 50 years of age in a 2nd-degree relative or below age 60 in a 1st-degree relative. * women on hormone replacement therapy for less than 2 years * women who are pregnant * individuals who regularly exercise more than 3 h/w * weight gain or loss of more than 5% of their body weight in the past 3 months * plans to begin a weight loss/exercise regimen during the trial * history of medical or surgical events that could affect digestion or swallowing * gastrointestinal surgeries, conditions or disorders, * any chronic diseases (including moderate to severe asthma, chronic lung disease, and kidney disease), * metabolic diseases * atherosclerosis * previous MI or stroke * cancer * fasting blood glucose levels greater than 126 mg/dL * blood pressure greater than 180/120 mmHg * medication use affecting digestion and absorption, metabolism (e.g., thyroid meds), lipid-lowering medications, medications for diabetes, steroid/hormone therapies, or current antibiotic cycles * medically prescribed or special diets * Food allergies (specific to the foods in the study, including wheat, dairy, and cottonseed oil) * fish oil supplements, * excessive alcohol use (greater than 3 drinks/d for men; greater than 2 drinks/d for women) * tobacco or nicotine use * underweight BMI (\<18.5 kg/m2)
