Dietary Fiber: Is it the Missing Link in Achieving Long Term Behavior Change?

The overall objective of this three-arm randomized controlled trial is to compare a dietary fiber-focused behavioral intervention to standard weight loss education for improving eating-related behavior and cognition, weight, and metabolic markers of chronic disease risk in a population of adults with obesity.

• Willingness to provide informed consent.

Exclusion Criteria:

• Metabolic, digestive, or allergic conditions or reactions that preclude consumption of whole food or food groups (e.g., irritable bowel syndrome, diverticulosis)
• History of gastric bypass surgery
• Currently taking glucagon like glucagon-like peptide-1 (GLP-1) Receptor Agonists
• Self-reported history of a diagnosed eating disorder
• Chronic disease (other than obesity)
