Your Microbiome, GLP-1 & Next-Generation Probiotics | Dr. Colleen Cutcliffe
The Gabby Reece Show
Travel, Circadian Rhythm and Gut Disruption
They discuss how travel, eating timing, and circadian shifts deplete the microbiome and practical preparation tips.
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

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