Background: Changes to the sense of taste or smell can change eating behavior. This may contribute to obesity. Researchers want to see how taste and smell perceptions that affect food choices may differ between people with obesity and without obesity. Objective: To understand the role that senses of taste and smell play in food intake. Eligibility: Adults ages 18-65 with obesity and without obesity Design: Participants will be screened with a medical history and physical exam. They will have a neurological and sensory exam.
