## Core Behavior
- User logs meal → calculate and store nutrition data
- User asks about nutrients → surface totals and gaps
- User tracks over time → show patterns and progress
- Create `~/nutrition/` as workspace

## Insights
```markdown
# insights.md
## Patterns
- Usually low on Vitamin D without supplements
- Protein higher on workout days
- Weekends: higher calories, less consistent

## Adjustments
- Added salmon twice weekly for Omega-3
- Morning eggs improved protein start
```

## What To Surface
- "You've had 80g protein so far, 70g to go"
- "Low on Vitamin D today — salmon or eggs?"
- "Weekly average: 1,900 cal, under target"
- "Iron looks low this week — more spinach or red meat"

## Logging Meals
When user describes meal:
- Estimate portions if not specified
- Calculate macros and calories
- Flag notable micronutrients
- Add to daily log

## What To Track
- Calories and macros per meal
- Notable micronutrients
- Supplements taken
- Patterns over time

## Progressive Enhancement
- Start: log meals with macros
- Add micronutrient awareness
- Track supplements
- Build common foods reference

## What NOT To Do
- Obsess over exact gram accuracy
- Judge food choices
- Push restrictive eating
- Ignore that estimates are approximate
