https://youtu.be/4CEV4URghPY Your metabolism affects everything from energy levels and cravings to long-term health. But, metabolic health is far more complex than calories in and calories out. In this episode of Next Level Health, Dr. Melinda Ring talks with integrative pharmacist and nutrition expert Dr. Lara Zakaria about new tools and technologies are changing the way we understand metabolism. They discuss: • What metabolic flexibility really means • Signs your metabolism may not be functioning optimally • How continuous glucose monitors (CGMs) reveal blood sugar patterns • The pros and cons of health wearables like Oura Ring, Apple Watch, Whoop, and Fitbit • What we're learning about GLP-1 medications and metabolic health • Why body composition matters more than weight or BMI You'll also hear practical strategies you can start using today to improve metabolic health, including strength training, nutrition, sleep, and stress management. If you've ever wondered why your energy crashes, why weight loss can be difficult, or how wearable health technology fits into the future of medicine, this conversation offers an evidence-based look at the science behind metabolism. 00:00 – Why Better Health Data Helps People Make Better Decisions A powerful insight into how the right information can drive lasting behavior change. 00:00:27 – Podcast Introduction: Tools to Improve Metabolic Health Dr. Melinda Ring introduces integrative pharmacist and nutrition expert Dr. Lara Zakaria. 00:00:58 – What Is a Healthy Metabolism?
