#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 dysfunction
• What HbA1c and fasting glucose really tell you
• The early signs of insulin resistance most people miss
• How muscle tissue protects against high glucose and insulin
• Why low-carb and intermittent fasting aren’t one-size-fits-all
• Practical nutrition and movement strategies for better metabolic flexibility
