The 30-Day CGM Challenge
Master Your Metabolism
Thirty days of real-time data on how your body responds to food, sleep, stress, and movement, with weekly live guidance from Julia and a small group doing it alongside you.
Next group starts Thursday, November 19. Registration closes Saturday, November 7.
Thirty Days From Now
Stop guessing. Start seeing.
Your labs may say "normal," and you still crash every afternoon. A continuous glucose monitor shows what a single blood draw can't: how your blood sugar moves through a real day, meal by meal.
- You know which meals keep your energy steady through the afternoon, and which ones set up the 2pm crash.
- You've seen, in your own data, how sleep, stress, and a ten-minute walk change your blood sugar.
- You've traded generic diet rules for a plan built from your own numbers.
- Food decisions feel clearer, because you're not guessing anymore.
This challenge is for you if
- You hit a wall most afternoons, or your energy feels unpredictable
- You want to understand how your body responds to different foods and eating patterns
- You've tried the generic advice and the last few pounds haven't budged
- You're curious how sleep, stress, exercise, sauna, or cold exposure affect your metabolism
- You watched a parent struggle with blood sugar and want to get ahead of it
- You want to fine-tune your nutrition for training, recovery, or focus at work
It's not the right fit if
- You use more than 500 units of insulin per hour
- You can't log meals in an app and look at your data
- You can't attend the live calls or watch the replays
- You have an MRI, CT scan, or diathermy treatment scheduled during the challenge
- You take hydroxyurea, or high doses of acetaminophen, vitamin C, or aspirin, which can affect CGM readings*

Enroll in the ChallengeMy Commitment to You
Come to the four live calls and track your data along the way.
If you don't come away with clear, personal insight into how your body responds to food, movement, sleep, and stress, I'll schedule a complimentary one-on-one session to go through your data with you.
Your Guide
Meet Julia
I'm Julia Callaghan, BS, AFMCP, CLT, a functional nutritionist in Charlotte, NC, and the founder of Innovative Nutrition NC. I help high-achieving, health-conscious adults figure out why they feel tired, bloated, or stuck, and what to address first.
Blood sugar is personal for me. As a kid, I was the one who had to leave class to eat a snack, because going too long without food left me shaky, dizzy, and irritable. These days I wear a CGM myself. Watching my own patterns in real time is still one of the most useful things I've done for my energy.
What I've learned, in more than 10 years of practice: normal is not the same as healthy, and the order you do things in matters as much as what you do. Don't wait until you're prediabetic to wear a CGM.
I hold a B.S. in Human Nutrition from Winthrop University, completed the Institute for Functional Medicine's AFMCP program, and am a Certified LEAP Therapist.
How It Works
Four weeks, one step at a time
Welcome to the 30-Day Challenge
We put sensors on together on the first call. You eat the way you normally do and learn your baseline.
Understanding your CGM data
You learn to read your curve: the meals that spike you, the ones that steady you, and why timing matters.
Finding your blood sugar sweet spot
Sensor two goes on. You test one change at a time: food order, a walk after meals, fewer simple carbs.
Sustaining success
You see how stress and sleep show up in your data, and leave with a plan that holds up in real life.
Questions
Frequently asked questions
Not anymore. A CGM is simply the clearest way to see how your own body handles food, sleep, stress, and movement. You don't need a diagnosis or a tech habit to learn from it.
Registration Closes Saturday, November 7
Your body is always communicating. Let's listen.
Two sensors. Four live calls. Thirty days of learning how your metabolism actually works.

Certain medications, including metformin, GLP-1 medications such as Ozempic, and others that affect how the body handles glucose, can influence CGM readings.
