Hosts: Sean Sale and Paul Rhodes
Welcome to Episode 26 of CTRL-ALT-DEV! Today, we are stripping back the format—no guests, no slides—to discuss one of the most unexpected and life-changing AI experiments we've built to date: the AI Meal Planner.
What started as a simple test to make cooking easier has morphed into a system that slashes food waste, completely eliminates duplicate supermarket purchases, and could easily save families up to £5,000 a year. We dive into the shocking reality of UK food waste, the concept of "reverse meal planning," and how Paul went from a Notion-based AI workflow to coding his own custom app in just 15 minutes.
Key Topics & Highlights:
- The Jaw-Dropping Stats on UK Food Waste: We set the scene with data from WRAP showing that UK households throw away 6 million tons of food and drink every year (costing £17 billion globally, or roughly £1,000 per family of four). A staggering 73% of this is perfectly edible food, and 80% of waste simply comes down to cooking too much or not using food in time. Surprisingly, 18-34-year-olds are the worst offenders.
- The Cost of Convenience: Sean makes a painful confession: he spent £5,000 on takeaways alone last year, bringing his total food budget to a shocking £13,000 annually. Paul shares how he used the financial app Snoop to realize he was wasting massive amounts of money on daily convenience store trips.
- Reverse Meal Planning: Why standard meal planning fails. Instead of starting with a blank sheet of paper and buying new ingredients, "reverse meal planning" starts with an inventory of what you already have in the fridge and pantry (prioritizing items that are expiring soon) and building a gap-fill shopping list from there.
- The MVP AI Workflow: Paul details his 15-minute Saturday routine: he uses Whisper Flow to audio-dictate his cupboard inventory, and then Claude Cowork scans his family's calendar, cross-references 17 digital recipe books, and pushes the required ingredients straight to Notion and the Bring! shopping app.
- From Prompt to Custom App in 15 Minutes: Using Claude Code and a solid Product Requirements Document (PRD), Paul actually built his own local meal planner app overnight to streamline the entire process, removing the need for third-party apps like Bring! and Notion.
- Scanning for UPFs (Ultra-Processed Foods): Inspired by Chris van Tulleken's book Ultra-Processed People, Paul talks about trying to eliminate UPFs. Since apps like Yuka only show nutritional scores, Paul is now integrating a custom barcode scanner into his app to cross-reference ingredients for UPFs while at the supermarket.
(Listener Challenge: Have you figured out a way to automate the checkout basket directly to Sainsbury's, Tesco, Aldi, or Ocado using AI? We are still experimenting with this and want to hear your workflows!
