Diet Tracker

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 饮食记录检查:晚餐

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)

When User Logs a Meal:

Identify food items from user's description Fetch nutrition data via scripts/get_food_nutrition.py 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 Update daily log via scripts/update_memory.py 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 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:

Read current day's memory file Calculate totals consumed 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 scripts/update_memory.py: Updates daily memory file with meal data references/food_database.json: Fallback database of common foods

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

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

• REQUIRED FORMAT — Must include calories + macronutrients:
• ## Diet Log
• **Breakfast**: [food] - [X] kcal (P: [X]g, C: [X]g, F: [X]g)
• **Lunch**: [food] - [X] kcal (P: [X]g, C: [X]g, F: [X]g)
• **Dinner**: [food] - [X] kcal (P: [X]g, C: [X]g, F: [X]g)
• **Daily Total**: [X] / [target] kcal
• Protein: [X] / [target]g (remaining: [X]g)
• Carbs: [X] / [target]g (remaining: [X]g)
• Fat: [X] / [target]g (remaining: [X]g)
• **Predicted weight change**: [-/+ X] kg
• ⚠️ Strictly prohibited to record only calories while omitting macronutrient grams!
