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

Why cravings may not be about willpower

How stress, aging, and travel deplete your gut

Key Takeaway

The goal isn’t perfection.

It’s resilience.

A strong, diverse microbiome helps your body handle stress, hormonal shifts, aging, and even dietary slip-ups. And unlike your genetics — your gut can change.

Start with food.

Use tools wisely.

Pay attention to your body.
