The Best Vibe-Coded Health System We've Ever Seen
<p>Mike Hudack (CEO of Sling Money, former executive at Meta, Monzo and Deliveroo) built a personal health data platform almost entirely using Claude Code — connecting his whole genome sequencing, blood tests, Oura Ring, 13 years of Withings data, and workout logs into one AI system. He did it as a side project, with prompts, while running a startup and raising three kids.</p><p><br /></p><p>In this episode, Mike walks through the exact system and how it caught something none of his individual apps could: a specific overtraining period, identified by cross-referencing HRV data with blood tests and workout logs. He also demos a food tracker he built in 10 minutes and explains why he's returning his Whoop.</p><p><br /></p><p>LINKS & RESOURCES</p><p>- Claude Code: <a rel="noopener noreferrer nofollow" href="https://claude.ai" target="_blank">https://claude.ai</a></p><p>- Oura Ring: <a rel="noopener noreferrer nofollow" href="https://ouraring.com" target="_blank">https://ouraring.com</a></p><p>- Withings: <a rel="noopener noreferrer nofollow" href="https://www.withings.com" target="_blank">https://www.withings.com</a></p><p>- Strong App: <a rel="noopener noreferrer nofollow" href="https://www.strong.app" target="_blank">https://www.strong.app</a></p><p>- <a rel="noopener noreferrer nofollow" href="http://DNAComplete.com" target="_blank">DNAComplete.com</a>: <a rel="noopener noreferrer nofollow" href="https://www.dnacomplete.com" target="_blank">https://www.dnacomplete.com</a></p><p>- SNPedia: <a rel="noopener noreferrer nofollow" href="https://www.snpedia.com" target="_blank">https://www.snpedia.com</a></p><p>- ElevenLabs: <a rel="noopener noreferrer nofollow" href="https://elevenlabs.io" target="_blank">https://elevenlabs.io</a></p><p>- OpenAI API: <a rel="noopener noreferrer nofollow" href="https://openai.com" target="_blank">https://openai.com</a></p><p><br /></p><p>TIMESTAMPS</p><p>0:00 Introduction</p><p>1:30 Mike's background — Facebook, Deliveroo, Monzo, Sling Money</p><p>3:02 Building a food tracker in 10 minutes</p><p>3:59 AI detects overtraining from cross-referenced data</p><p>5:30 Whole genome sequencing analysis with Claude Code</p><p>8:23 Why conversational AI beats dashboards</p><p>9:46 Claude vs ChatGPT as your doctor</p><p>11:00 Layering data: Oura, Withings (13+ years), Strong app</p><p>13:30 The FatSecret problem — £1,500/month for UK access</p><p>15:00 MCP server architecture</p><p>16:50 Why Mike is returning his Whoop</p><p>18:00 WhatsApp-based health AI via Open Claude</p><p>19:24 "Most exciting thing in the last hundred years"</p><p>20:30 Proactive daily health summaries</p><p><br /></p><p>━━━━━━━━━━━━━━━━━━━━━━</p><p><br /></p><p>ABOUT HEALTHSTACKS</p><p>AI workflows for training, nutrition, and recovery you can steal today.</p><p><br /></p><p>Hosts: Will Read & James Grant</p><p>Website: <a rel="noopener noreferrer nofollow" href="https://healthstacks.ai" target="_blank">https://healthstacks.ai</a></p><p>Subscribe for new episodes every Wednesday</p><p><br /></p><p>━━━━━━━━━━━━━━━━━━━━━━</p><p><br /></p><p>#HealthStacks #AIHealth #ClaudeCode #OuraRing #Whoop #GenomicData #HealthData #PersonalAI</p><p><br /></p>

How I Built an AI That Personalises Workouts to My Body: HealthStacks with James McAulay
<pre><code>James McAulay connected his Garmin, Strava, TrainingPeaks, gym app, and a 65-page blood work report into a single AI coaching system inside Claude Desktop — no code required. He runs four live demos showing exactly how it works. The system critiques recent runs using sleep and HRV data, designs structured workouts based on readiness metrics, spots gaps in gym programming, and personalises post-workout nutrition from specific blood markers. What you'll learn: - How to connect multiple health data sources to one AI agent using MCP servers - A system prompt structure that gives AI enough context to actually coach you - How to turn blood work into personalised, actionable nutrition guidance - The honest limitations — what AI coaching can and cannot replace Resources: www.healthstacks.ai/episodes/ep3-james-mcaulay</code></pre>
