The Blood Sugar & CGM Series

The Blood Sugar & CGM Series

Last reviewed: August 2026

You have been told your labs are normal. You are still exhausted, still foggy, still carrying weight that will not move. This series is about the gap between those two things.

Over eight episodes I walk through what your blood sugar is actually doing, why so many of us hit a wall in our forties and fifties, what a continuous glucose monitor can show you, what it genuinely cannot, and what to do with any of it. Each episode stands on its own, so start wherever your question is.

Who this series is for

The woman who got a lab result nobody explained. The woman with symptoms and no answers. The woman who has been told to eat less and move more by someone who has never looked at her actual numbers.

If you have ever left an appointment holding a piece of paper that said normal while feeling anything but, this is for you.

What you will learn

  • What a lab reference range actually measures, and why normal is not the same as well

  • The three blood sugar numbers worth knowing, including one you can calculate tonight

  • Why insulin resistance becomes so common during perimenopause, and why nobody is discussing it while you talk about estrogen

  • How a continuous glucose monitor works, and how to decide whether you want one

  • What a CGM cannot tell you, and why data on its own is not the answer

  • What actually improves when you do this work, and in what order

  • Where to start, in what order, without waiting for permission

The episodes

Part 1 — Your Labs Are "Normal." So Why Do You Feel Like This?

Where reference ranges come from, why only about one in eight American adults is in good metabolic health, and the three numbers that tell a more honest story than the word normal ever will. Read or listen to part one.

Part 2 — I Haven't Changed Anything. So Why Am I Gaining Weight?

The weight is a symptom, and a late one. What changed years earlier was invisible: your body quietly got worse at handling sugar. Read or listen to part two.

Part 3 — Your Fasting Glucose and A1c Are Creeping Up. Nobody's Worried.

The drift you can see on your own lab results is what insulin losing ground looks like. It has been compensating for years. And insulin is a hormone — the one nobody has mentioned while you have been having a detailed conversation about estrogen. Coming soon.

Part 4 — What a CGM Actually Is, and What It Shows You

How the device works, what a day of data looks like, and the four things worth watching. It does not measure glucose — it measures yours, which is the part that matters after twenty years of advice built for someone else. Coming soon.

Part 5 — Getting One and Wearing One

The practical episode. How to order one without a prescription, what it costs, whether your HSA covers it, how to apply it, what the first two days feel like, how long to wear it, and who should skip it altogether. Coming soon.

Part 6 — What a CGM Cannot Tell You

The honest limits of the device, and why a spike is not automatically a failure. Coming soon.

Part 7 — What Comes Back First

It improves in a particular order, and the weight is last. Energy first, mental clarity next. Knowing the sequence is what stops you quitting in week three because the scale has not moved. Coming soon.

Part 8 — In the Driver's Seat: Your First 30 Days

The order of operations. What to test, what to change, and what to do if your doctor says no. Coming soon.

The 5 Numbers Your Doctor Calls "Normal" — But Aren't Optimal

If you've been told your labs look "fine" but you still feel tired, foggy, and not-quite-right, this is for you.

This free guide shows you:

  • The 5 numbers that expose insulin resistance early — including the one most doctors skip unless you ask for it by name

  • What "optimal" actually looks like for each — not the low-bar "normal" that leaves you feeling dismissed

  • A printable list to hand your doctor, so nothing gets missed at your appointment

  • What to do if your doctor won't run them — including how to order them yourself

  • Clear, friendly explanations in both US and international units

No guesswork. No fear tactics. Just the numbers that actually tell the truth about your metabolic health.
