What Should My Blood Sugar Be Doing?

Episode 294· Streamed Live On May 28, 2025· webinar

Many viewers write in with the same puzzle. My blood sugar was fine at bedtime, I fasted all night, and I woke up to a high number, so what is going on? In this episode, Dr. Scott Saunders answers the real question behind it. What should your blood sugar actually be doing, and what number should you aim for? His answer is likely lower than what your doctor has told you, because his goal is for you to need less medication, not more.

Dr. Saunders explains how to check your blood sugar accurately, why the optimum fasting range is 70 to 90, and what the dawn effect really tells you. He walks through the cell-level mechanism of insulin resistance using a simple fuel-tank analogy, then answers a full hour of viewer questions on berberine, ferritin, gabapentin, cholesterol, gout, and more.

In this episode, Dr. Saunders covers:

  • Why a smartwatch cannot truly measure your blood sugar, and what a continuous glucose monitor actually reads
  • What your fasting blood sugar should really be, and why it is lower than the usual doctor target
  • The dawn effect, and why your morning number can climb even when you have not eaten
  • The cell and insulin-receptor mechanism behind insulin resistance, explained with a fuel-tank analogy
  • The two levers that make you more insulin sensitive: cutting glucose and exercise
  • Why adding insulin to an insulin-resistant body can make things worse
  • How berberine compares to metformin, and how it is typically dosed
  • Viewer Q&A on ferritin, gabapentin, cholesterol targets, gout, and lifting your heels for circulation
