Diet Tracker

This skill helps track daily diet and achieve weight loss goals with automated meal reminders.

Trigger Conditions

User might say:

• - "I had [food] for lunch/dinner"
• "What's my remaining calorie budget?"
• "How many calories have I eaten today?"
• "Log my meal"
• "Check my diet progress"

Or automatically triggered by cron job for meal reminders.

Cron Job Integration

This skill works with automated cron jobs:

• - Lunch reminder: ~12:30 (checks if lunch logged, sends reminder if not)
• Dinner reminder: ~18:00 (checks if dinner logged, sends reminder if not)

Cron job system event: 饮食记录检查:午餐 or INLINECODE1

User Profile (Required)

The skill reads from USER.md:

• - Daily calorie target (default: 1650 kcal)
• Macronutrient targets (protein/carbs/fat)
• Height, weight, age, gender, activity level (for TDEE calculation)

Activity levels:

• - Sedentary (little or no exercise)
• Lightly active (light exercise 1-3 days/week)
• Moderately active (moderate exercise 3-5 days/week)
• Very active (hard exercise 6-7 days/week)
• Extra active (very hard exercise + physical job)

Workflow

When User Logs a Meal:

1. 1. Identify food items from user's description
2. Fetch nutrition data via INLINECODE3

- MUST GET: calories(kcal), protein(g), carbs(g), fat(g) - Searches web for calorie/protein/carbs/fat info - Falls back to references/food_database.json if needed - If complete nutrition data cannot be found, MUST clearly inform user of estimated values

1. 3. Update daily log via INLINECODE5

- Saves to memory/YYYY-MM-DD.md - RECORD FORMAT: Food Name - XX kcal (P: XXg, C: XXg, F: XXg) - Calculates meal totals - Updates daily running totals

1. 4. Report to user:

- MUST REPORT: calories + protein/carbs/fat grams - Today's consumed / remaining calories - MUST REPORT: Remaining macronutrient budgets - Predicted weight change based on deficit/surplus

When User Asks for Status:

1. 1. Read current day's memory file
2. Calculate totals consumed
3. Report:

- Remaining calorie budget - Remaining protein/carbs/fat (if targets set) - Weight change prediction

Scripts

• - scripts/get_food_nutrition.py: Fetches nutrition info + calculates TDEE
• INLINECODE9: Updates daily memory file with meal data
• INLINECODE10: Fallback database of common foods

Error Handling

Common Issues

Issue: "Cannot read USER.md" or missing user data

• - Cause: User profile not configured
• Solution: Ask user for height, weight, age, gender, activity level, and calorie target

Issue: Nutrition lookup fails for uncommon foods

• - Cause: Food not found in online databases
• Solution: Ask user for approximate calorie count or use similar food from database

Issue: Multiple food items in one meal

• - Cause: User says "I had pizza, salad, and coke"
• Solution: Process each item separately, sum the nutrition values

Data Format

Daily Memory Entry (memory/YYYY-MM-DD.md)

REQUIRED FORMAT — Must include calories + macronutrients:

CODEBLOCK0

⚠️ Strictly prohibited to record only calories while omitting macronutrient grams!
