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

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)

Workflow

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

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:

## 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!
