Caloric Restriction: A Key to Longevity with Rozalyn Anderson

Season 1, Ep. 2

In this conversation, Rozalyn Anderson and Martin explore the complexities of aging, the impact of caloric restriction on longevity, and the scientific journey that led Rozalyn to her current research. They discuss the intersection of aging and disease, the role of adipose tissue, and the importance of understanding aging in the context of health and disease. The conversation highlights the significance of caloric restriction studies in both animal models and humans, emphasizing the need for a deeper understanding of the aging process. In this conversation, Rozalyn Anderson discusses the implications of caloric restriction studies, the role of GLP-1 in metabolic health, and the challenges of aging in the context of obesity. She highlights the significance of senescent cells in aging and the potential of stem cell therapies. The discussion also touches on the need for more geriatricians and the importance of investing in aging research and healthcare to improve outcomes for older adults.
