042: Hunger Hormones and Lifestyle Medicine with Dr. Moisés Roizental

As part of the drive to improve people’s health, Andrés paired up with Dr. Moisés Roizental and Dr. Patricia Jaimes to form Hambre y Hormonas (Hunger and Hormones). This project aims to teach people how their body works so that they can make decisions based on science and results. Join us today as we talk to Dr. Moisés Roizental (Harvard-trained interventional radiologist and vascular specialist) about this exciting venture and the factors that led him to adopt a more functional medicine approach to his own health, and the health of his patients. From where Dr. Roi was educated, to his current job and the procedures he most commonly uses, to how he and Andrés met, this episode has it all! We dive into the physiology of lifestyle-related diseases, and how merely taking medication is not enough to solve the underlying problem. Dr. Roi explains why he made the shift from treating patients with diseases to disease prevention, and the combination of treatments he suggests. Andrés and Dr. Roi break down the four main hormones responsible for lifestyle-related diseases (Ghrelin, Leptin, Insulin, and Cortisol): what they do, how they are linked to disease, and how they are regulated. Andrés cites a wealth of studies supporting the impact of lifestyle changes in preventing disease, while Dr. Roi explains why he prescribes dietary shifts as well as bariatric embolization for long-lasting results. So, to find out first-hand why marrying functional medicine and mainstream medicine makes the dream team, tune in today!
