Can AI Stop GLP-1 Patients From Churning? Ep. 8 with Dr. Paul Sacher
<p>The economics of DTC GLP-1 care are getting harder. Customer acquisition costs keeps rising, price is getting pushed down, and more patients are willing to switch provider for the cheapest pen.</p><p>That leaves DTC companies with the worst possible equation: lower gross profit per month and a customer base full of switchers who may not stay long enough to pay back acquisition.</p><p>In this episode, I speak with Dr. Paul Sacher about where AI can actually show up on the GLP-1 profit and loss statement. Paul has spent more than two decades in obesity management and has worked across digital-health providers building and evaluating patient-facing AI systems. </p><p>His team has analysed close to 100,000 support tickets, churn data, and patient interviews, which makes this a practical conversation rather than another abstract debate about healthcare chatbots.</p><p><strong>Timestamps: </strong>00:00 Why AI in GLP-1 care is not just a chatbot</p><p>04:58 Why 24/7 support matters for patients</p><p>07:19 Onboarding, side effects, and early churn</p><p>12:18 Why app engagement can mislead operators</p><p>15:39 Switchers, maintenance, and personalised support</p><p>20:00 What providers get wrong when adding AI</p><p>37:46 The behavioural data moat in GLP-1 care</p><p>48:35 Safety, regulation, and clinical escalation</p><p><br></p><p>Subscribe to the newsletter: <a href="https://www.glp1digest.com/" target="_blank" rel="noopener noreferer">https://www.glp1digest.com/</a><br></p>

Genetics Could Decide Who Wins the GLP-1 Market, Ep. 7 with 23andMe’s Dr. Adam Auton
<p>Why do two people taking the same GLP-1 have radically different results? Part of the answer may be written in their DNA.Dr. Adam Auton is Vice President of Human Genetics at 23andMe and a senior author of the 2026 Nature study, <a href="https://www.nature.com/articles/s41586-026-10330-z" target="_blank" rel="ugc noopener noreferrer">“Genetic predictors of GLP1 receptor agonist weight loss and side effects.”</a> </p><p>The study examined 27,885 GLP-1 users to investigate whether genetic variation can help predict weight loss, nausea, and vomiting.</p><p>In this episode, we discuss what polygenic risk scores actually reveal, why genetics is risk rather than fate, and how variants in the GLP1R and GIPR genes may shape a patient’s response to semaglutide and tirzepatide.</p><p>We also explore the commercial consequences. As the obesity-drug market becomes more crowded, genetics could help new entrants identify patients who respond poorly to existing treatments, support more personalised care, and turn patient selection into a source of competitive advantage.</p><p>Read and subscribe to GLP-1 Digest: <a href="https://www.glp1digest.com/" target="_blank" rel="ugc noopener noreferrer">https://www.glp1digest.com/</a></p><p><br /></p><p>Timestamps: </p><p> 00:00 Polygenic risk scores and why genetics is not fate</p><p> 17:39 Why genetic risk scores vary by ancestry</p><p> 24:03 Inside 23andMe’s GLP-1 response study</p><p> 27:24 Predicting weight loss and side effects from DNA</p><p> 33:09 How reliable are self-reported data and prediction models?</p><p> 39:48 Genetics and the next generation of obesity drugs</p><p> 44:57 Can genetics predict weight regain after GLP-1s?</p><p> 48:11 Could genetics decide who wins the GLP-1 market?</p>

🎧 Can Peptides Become a Real DTC Business? Ep.6 with Tim Gutwald
<p>Peptides may already be a billion-dollar grey market. But if they move into legal compounding, can they become a real DTC healthcare business?</p><p><br></p><p>I speak with Tim Gutwald, a healthtech lawyer with roughly 20 years of experience across telehealth, prescribing, compounding and DTC healthcare, about the three things founders need to get right: legitimate pharma-grade API, defensible clinical protocols & enough internal data to market peptides beyond vague wellness claims.</p><p><br></p><p>We also discuss whether peptides are likely to become a standalone category, or simply a cross-sell around GLP-1s, TRT and longevity.</p><p><br></p><p>Subscribe: <a href="https://www.glp1digest.com/subscribe" target="_blank" rel="noopener noreferer">https://www.glp1digest.com/subscribe</a></p><p><br></p><p> <strong>Chapters</strong></p><p>00:00 What is happening in the peptide market?</p><p>03:01 Category 1, Category 2, and the FDA review process</p><p>08:19 Why DTC demand is driving regulation</p><p>10:41 Pharma-grade API and the peptide supply-chain problem</p><p>14:46 Clinicians, protocols, and prescribing risk</p><p>20:16 Advertising claims, testimonials, and internal data</p><p>30:00 What founders need to get right before launching</p><p>38:23 Schedule II drugs, telehealth prescribing, and affiliate risk</p><p>51:59 Why affiliate marketing is risky in DTC healthcare</p>
