FOR WOMEN OVER 40
It wasn't your discipline.
The Metabolic Fluency Workshop, from Fast To Thrive, is a master's in your own body.
Eight weeks of live online teaching on how your body actually uses fuel, how your hormones move, and how to time eating and fasting to that movement rather than fighting it.
Grounded in the Fast Like a Girl® framework by Dr. Mindy Pelz, and taught live by me every week—never pre-recorded.
By the end, you'll be able to read your own body well enough to make decisions in it, without needing me standing next to you. That's what fluency means here, and it's the whole point.
Who is this for?
You're over 40. What used to work stopped working, and the advice you got was that this is just part of life.
Whether you're still cycling, somewhere in perimenopause and not sure which end, or years past your last period, this was built for you.
Your body still responds to rhythm after your periods stop. What changes is that your body stops setting the schedule for you. So instead of following a cycle, you learn to choose a rhythm and run it deliberately—which is why learning to read your own signals matters more, not less.
I learned this the way you're about to.
I don't come from the healthcare world.
For most of my career, I was a managing director at a global consulting firm, working in finance, accounting, and IT. I learned all of this the way you're about to — as a woman trying to work out what was happening to her own body.
In 2018, I was 46 and thriving, and then a ski accident tore my ACL, MCL, and meniscus. Six weeks non-weight-bearing, then months of rehab. Somewhere in there, my nervous system turned on me. I started having panic attacks—mostly about blood clots, mostly when there was no clot.
Around 50, I noticed belly fat for the first time in my life. I asked my doctor whether the anxiety might have something to do with menopause.
I was told I was just an anxious person.
My personal trainer handed me The Menopause Reset. Every page read like it had been written about me. I joined Dr. Mindy Pelz’s Reset Academy in 2022, and I haven't had a panic attack since. That's my experience — I can't promise it's yours.
Then I got obsessed, in the best way. I read everything, tried everything, learned the physiology well enough to explain it. In spring 2024, when Dr. Mindy Pelz announced the first Fast Like a Girl coach certification, I enrolled the same day.
That was also the year my mother was diagnosed with colon cancer.
That summer, at a retreat, Dr. Mindy shared a butterfly metaphor from Age Like a Girl. My mother had always said she'd come back as a butterfly. I sat there and cried, because it felt like confirmation that I was exactly where I was supposed to be. She had insisted I go. I flew home early, and she passed that Thursday.
The Fast To Thrive logo is a butterfly with a woman's profile. I had it designed in her honor, and it's why I remember every day who this work is for.
I retired in 2025 and built this Fast To Thrive. September will be my fourth cohort. More than twenty women have done it now — three groups, plus seven I've worked with one-on-one. What one of them said after the first cohort is still the reason I keep running them: “Fast Like a Girl should be required reading for every woman”.
I don't promise results. I promise you'll understand your own body well enough to make decisions in it.

About the break week
I'll be out of state with family from October 5 through the 13th, and genuinely offline. You won't be waiting on me for anything: after the September 30 class you'll have everything you need for the break week and for the reset that follows. I'm back for class on the 14th.
Two ways to get started
Every one-on-one path runs alongside the workshop because I'd rather not spend 1-on-1 coaching hours teaching foundations you can get just as well in the group.
$400 The 8-week Metabolic Fluency Workshop
Eight 90-minute live classes
The guided 30-Day Reset
Your own cycle-aware fasting plan
A private Facebook group for your cohort, open after the eight weeks end
Time in every class for your questions, answered live
No fasting experience needed
For many women, this on its own is all they need.

Already know you're in? Enroll here.
Longer engagements exist for women who need them — six months ($5,250) and twelve months ($10,250). Both start with a call rather than a checkout page, because at that length the fit has to be right on both sides.
Inside any of these, the workshop costs $250 — not the $400 it costs on its own.
Why I recommend adding the 1-on-1 coaching
In the workshop, I teach the method to the whole group. That teaching is the same for every woman in the room, and it should be — it's the foundation.
But a foundation is not a plan. Two women can sit through the very same class and need different things the next morning. One is still cycling and can time everything to it. One is in perimenopause and can't, because the timing stopped being predictable. One finished menopause six years back.
Our private sessions are where we take what you're learning in the group and apply it to you — your stage of life, your numbers, your actual week, and anything your doctor is already managing, which we work alongside and never around.
Weeks 1 through 3 cover the foundations, so by our first coaching session you already have the framework. Which means we don't spend our first hour on the basics. We spend it on you. Then the 30-Day Reset begins — and you start it already holding a plan we built together.
Thirty minutes, just the two of us.
We'll talk about what's changed for you, what you've already tried, and what you're hoping for — and I'll tell you honestly whether I'm the right person for it.
What you’ll need
You don’t need to have everything figured out before registering. These tools are here to support the learning experience, and we’ll walk through how to use them together during the workshop.
To get the most out of The Metabolic Fluency Workshop, you’ll want access to these tools.
Required (About $128, and yours to keep well beyond the eight weeks)
Dr. Mindy Pelz’s book Fast Like a Girl (This is the foundational resource we’ll reference throughout the workshop.)
A Keto-Mojo (A glucose and ketone measurement tool)
Ultimate Keto-Mojo Blood Glucose & Ketone Meter Kit
Save 10% when you use the provided affiliate link
Optional (Highly recommended)
A continuous glucose monitor (CGM)
I recommend the 2‑sensor package ($99 for a 1‑month supply). This supports the 30‑day reset and helps you see how fasting and foods impact your glucose in real time — giving you personalized insight you can use to adjust and learn.
What women have said
More than twenty women have finished this program. Here's what three of them said, in their words, with their permission.
“This program changed my life. As I’ve gotten older and the things I’ve always done weren’t getting the same results, I’ve been on a health and wellness journey for about 2 years. Lisa came at exactly the right time to take me to the whole next level. I feel like I’m relearning everything I thought to be true, and Lisa is a wealth of knowledge and support. All of the material is backed by science, and the results are undeniable. I feel in control, I have data to review and reflect and make adjustments as I learn. This is a new lifestyle, not a fad. And Lisa is the perfect person to take you on this journey”
“My primary goal was to improve my gut health and decrease my reliance on digestive supplements. My secondary goal was to shed a few excess pounds. With Lisa’s coaching and the group exchange, I’m now off the supplements and I’m down one size…woo-hoo! Thanks for all the support. ”
“I learned a great deal about the female body and nutrition throughout the eight-week session with Lisa. It’s as though I have new superhero powers that revitalized my energy, mood, and sleep. Being post menopause is now a beautiful place to be.”
Before you enroll
If something can't wait, don't wait for me. Stop, eat, let your body settle, and then tell me what happened. If it persists, call your doctor. Nothing in this program is worth pushing through when you feel unwell.
I answer email and text within 24 to 48 hours on weekdays. Private email and text access are part of the coaching package rather than the workshop on its own. I'd rather tell you now than have you find out in week 3.
This is wellness education. It doesn't diagnose, treat or cure anything, and it doesn't replace your doctor—it runs alongside whatever your doctor is already managing.
