The Problem

Too much data, not enough guidance

Generic recommendations → low relevance

Users drop off due to fatigue + confusion

Retrospect, Shirs

AI is only valuable when grounded in real user context. Trust is also a design problem, not just a technical one. Constrains (clinical, privacy) can strengthen product decisions

Core Concept

Foodhak Assistant Insights

“You’ve had high sodium for 3 days — here’s a small change today.”

“You’ve had high sodium for 3 days,

here’s a small change today.”

Interprets user behavior (food, sleep, activity)

Surfaces insights at the right moment

Explains why recommendations are made

System Thinking

Closed-loop design

User data input —> Processing (AI engine, RAG controlled env.) —> Contextual recommendations

Key Product Decisions

Adaptive Experience

Recovery needed

  • Improved adherence to routines

  • More stable weight management

  • Reduced burnout from tracking

  • Better recovery and sleep awareness

  • Scalable personalization without coaching

  • Strong privacy moat (on-device data)

  • Clinically defensible system

  • Foundation for long-term AI health optimization

  • Clear differentiation from calorie trackers

  • Premium personalization tier

  • Pathway to clinical + enterprise partnerships

  • Potential for publishable health outcomes

Deeper Personalization Using Longitudinal Data
Not reacting to today → learning patterns over weeks/months

Examples:

  • Pattern Detection

    “You consistently feel fatigued on low-carb days after 3PM”

  • Adaptive Recommendations

    • Week 1: “Reduce sugar intake”

    • Week 4: “Switch lunch composition — your energy drops after this specific meal pattern”

  • Personal Baselines (not generic)

    • Your “normal” sleep = 6.5h

    • Your “optimal” = 7.2h (based on recovery data)

Comprehensive Visualization
Charts ≠ understanding
Allow Predictive Insights
“What Happens If…”

Examples:

  • Order Detection

    "You ordered food from Doordash.."

  • Adaptive

    • Quick log?

  • Prediction Baseline

    • User eats lunch at 12PM - 1PM everyday.

    • You consistently snack at …

    • You might feel, want to …
