#284 - Glucose metabolism explained: HbA1c, insulin resistance, and strategies for better energy | Dr. Ben Bikman & Mike Haney
If you want to improve your energy and long-term health, start by understanding how your body uses glucose.In this episode of A Whole New Level, Dr. Benjamin Bikman, scientist and author of Why We Get Sick, joins Mike Haney to unpack the science of glucose metabolism and insulin resistance—and why blood sugar isn’t the whole story.Dr. Bikman explains how insulin regulates energy balance, why HbA1c is only part of the picture, and how chronic high insulin can silently drive weight gain, fatigue, and metabolic disease. He also shares practical ways to lower insulin naturally through diet, exercise, and daily habits.They discuss:Why insulin, not glucose, is the root of metabolic dysfunctionWhat HbA1c and fasting glucose really tell youThe early signs of insulin resistance most people missHow muscle tissue protects against high glucose and insulinWhy low-carb and intermittent fasting aren’t one-size-fits-allPractical nutrition and movement strategies for better metabolic flexibilitySign Up to Get Your Free Ultimate Guide to Glucose: https://levels.link/wnl🎙 What Ben Bikman, PhD, & Mike Haney discuss:[3:42] — Why glucose isn’t the full story in metabolic health[7:58] — Insulin’s central role in energy and fat storage[13:10] — What HbA1c actually tells you—and what it misses[19:23] — The first signs of insulin resistance most people overlook[25:46] — Why muscle is a “glucose sink” that protects your metabolism[32:15] — How modern diets overload insulin, not just glucose[39:52] — The difference between being lean and being metabolically healthy[46:08] — Simple daily habits that lower insulin naturally[54:41] — Why “normal” lab ranges for insulin are misleading[1:02:17] — Practical steps to build metabolic flexibility and better energyLevels helps you see how food affects your health, empowering you with the tools needed to achieve health goals and improve healthspan.
