GIP and obesity due to melanocortin 4 receptor deficiency: Unlike the narrative review by Christensen et al. [38], which provides expert commentary on potential dietary strategies for patients prescribed GLP-1 and GIP/GLP-1RAs, and the joint advisory from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association, and the Obesity Society [35], which offers practice-oriented guidance, this scoping review systematically catalogs clinical trials that report on actual dietary intake, craving behavior, and assessment methods.
