Dalia Perelman, Research Dietician, Department of Medicine, Stanford University

Research Description: As a research dietitian, I collaborate with NORC and the School of Medicine to explore how diet influences the gut microbiome and metabolic health, advancing personalized nutrition. By integrating technologies like continuous glucose monitoring and microbiome analysis, we aim to develop individualized dietary interventions that bridge clinical practice and research. In collaboration with Dr. McLaughlin, I design and conduct studies on the mechanisms driving chronic diseases related to weight gain, with a particular focus on adipocyte responses to excess calorie storage. Our overfeeding studies reveal how adipocytes initiate physiological changes that impact metabolic health, providing key insights for targeted interventions. Additionally, we are investigating the cellular and physiological effects of GLP-1-based weight loss medications to guide more precise treatment prescriptions and offer informed dietary and lifestyle counseling to patients. I collaborate with Drs. McLaughlin and Snyder to develop precision nutrition strategies aimed at improving glycemic control and insulin sensitivity, enhancing health outcomes for those at risk of type 2 diabetes. Additionally, I work with Drs. Gardner and Sonnenburg to study the interaction between diet, gut microbiota, and metabolic regulation, translating these insights into personalized nutrition plans tailored to individuals' microbiome profiles. I actively mentor new dietitians and promote interdisciplinary collaboration to advance personalized nutrition. Committed to innovation, I aim to develop evidence-based interventions that can revolutionize the management of metabolic diseases globally. I collaborate extensively with many members of the NORC.
