Your Microbiome, GLP-1 & Next-Generation Probiotics | Dr. Colleen Cutcliffe
The Gabby Reece Show
Practical Start: Food First, Then Tools
Colleen reiterates starting with nutrition, using supplements when needed, and avoiding shame about using tools.
What if your metabolism, cravings, immune system — even your hormones — are being shaped by your gut?
In this episode of The Gabby Reece Show, Gabby sits down with microbiome scientist and Pendulum co-founder Dr. Colleen Cutcliffe to break down the real science behind gut health — beyond the buzzwords.
From premature birth and early antibiotic exposure to GLP-1, estrogen, cravings, and perimenopause, this conversation connects the dots between your microbiome and nearly every major system in your body.
If you’ve ever thought:
“Why am I gaining weight when nothing changed?”
“Why am I suddenly sensitive to foods?”
“Is this just aging… or something else?”
“Are GLP-1 drugs the only option?”
This episode will shift how you think about your body.
In This Episode, We Cover:
Why the microbiome is connected to all 11 organ systems
How early antibiotic use may affect long-term metabolic health
The truth about GLP-1 — and how your body produces it naturally
Why Akkermansia is considered a “keystone strain”
Gut health and perimenopause: what’s really happening
Estrogen, menopause, and emerging microbiome research

The goal isn’t perfection.

Start with food.
Use tools wisely.
Pay attention to your body.
