How Does Your Body React To Antibiotics? | Impact of Antibiotics Ep193

About this video

Pendulum co-founder and CEO Colleen Cutliff explains what gut health means in practical terms — the symptoms that suggest it is off — and how antibiotics can disrupt the microbiome, a disturbance the speakers say can be countered with deliberate rebuilding strategies. She distinguishes probiotics, prebiotics, postbiotics, and synbiotics, and spotlights Akkermansia as a keystone strain. Much of the episode explores the gut–metabolism axis: Cutliff argues gut microbes help metabolize sugars, generate satiety signals including gut-derived GLP-1 activity, and shape cravings, which is why she links microbiome loss to age-related metabolic decline. The pair also weigh how widely used metabolic drugs, including metformin and GLP-1 medications, interact with gut health over the long term. The episode carries a paid promotion for the guest’s probiotic company.

Key takeaways

• Antibiotic use is presented as a microbiome event with long tails — the speakers argue recovery should be planned, not assumed.
• The ‘biotics’ are not interchangeable: each category plays a different role in feeding, seeding, or supplying microbial products.
• Keystone strains matter disproportionately; losing specific microbes can remove whole metabolic functions, per Cutliff.
• Cravings are partly a gut story in her telling, because microbes participate in the satiety signaling that tells the brain a meal is done.
• Longevity interest in diabetes drugs is, she argues, really interest in sugar metabolism — which runs through the gut.
