Episode 459: Why Insulin Matters

Episode 459: Why Insulin Matters

Author: Ali Miller RD August 25, 2025 Duration: 54:07
In this episode, we shine a spotlight on insulin—an often overlooked but crucial hormone that plays a central role in metabolism and overall health. While blood sugar gets a lot of attention, insulin is the key regulator behind it, influencing energy storage, fat metabolism, and cellular function. We explore how insulin resistance develops, the early signs to watch for, and why it’s so important to address this root issue to prevent chronic disease. We also discuss how ketogenic and low-carb diets can help regulate insulin levels, improve metabolic flexibility, and support weight management. This episode provides clear, functional insights into insulin’s role and practical strategies for balancing it through nutrition and lifestyle, making it a must-listen for anyone interested in metabolic health and disease prevention.
