    "calories": 450,
    "protein": 35,
    "carbs": 45,
    "fat": 12,
    "timestamp": "2026-03-15T12:30:00Z"
  }
}
```

### Get Daily Stats

```json
{
  "action": "get_stats",
  "date": "2026-03-15"
}
```

Output:
```json
{
  "daily_stats": {
    "calories": 1450,
    "protein": 89,
    "carbs": 134,
    "fat": 67
  },
  "remaining": {

  }
}
```

    "diet_type": "balanced",
    "allergies": ["nuts", "shellfish"],

  }
}
```

## Diet Types

- **balanced**: Standard macro distribution
- **keto**: High fat, low carb
- **vegan**: Plant-based only
- **paleo**: Whole foods, no processed
- **bulking**: High calorie, high protein
- **cutting**: Calorie deficit, high protein

## Nutritional Data

Tracked macros:
- Calories (kcal)
- Protein (g)
- Carbohydrates (g)

## Meal Logging Methods

1. **Manual entry**: Provide all nutritional values
2. **Food database**: Look up common foods
3. **Recipe analysis**: Parse recipe ingredients
4. **Photo logging**: Estimate from image (experimental)

## Suggestion Algorithm

Meal suggestions based on:
- Remaining daily targets
- Dietary preferences/allergies
- Cuisine preferences
- Meal timing (breakfast/lunch/dinner)
- Historical food choices

## Example Workflow

1. Set daily goals on first use
2. Log meals throughout the day
3. Check remaining targets before next meal
4. Get suggestions for balanced nutrition
5. Review weekly trends

## Data Storage

Nutrition data stored locally in JSON format:
- Daily logs: nutrition/YYYY-MM-DD.json
- Goals: nutrition/goals.json
- Preferences: nutrition/preferences.json

## Integration

Works with:
