Diet Tracker

This skill helps you track your daily diet and achieve your weight loss goals.

Usage

1. The skill will read User related info in USER.md to get:

   • Your daily calorie target
   • Your height, weight, age, gender, and activity level to calculate TDEE.

2. When you provide information about your meals (e.g., "I had a sandwich for lunch"), this skill will:

   • Identify the food items in your meal.
   • Use the get_food_nutrition.py script to fetch nutrition information (calories, protein, carbs, fat) from the web.
   • Add the meal information and nutrition details to the current day's memory file (memory/YYYY-MM-DD.md).
   • Calculate the total calories and macronutrients for the meal.
   • Update the total daily intake and remaining calorie budget.
     • Also predict weight change based on daily calories.

3. When you ask about your remaining calorie budget, this skill will:

   • Read the current day’s memory file.
   • Calculate the total calories consumed so far.
   • Subtract the consumed calories from your daily calorie goal (found in USER.md).
   • Report the remaining calories.
     • Also predict weight change based on accumulated daily calories.

Scripts

• scripts/get_food_nutrition.py: Fetches nutrition information for a given food item from the web and calculates TDEE.
• scripts/update_memory.py: Updates the current day’s memory file with meal information and nutrition details.

Data

• references/food_database.json: A database of common food items and their nutrition information (used as a fallback).

Workflow

1. Diet-tracker skill read User related info from USER.md to get:

5. Skill uses scripts/update_memory.py to update the current day’s memory file.
6. Skill calculates the total calories and macronutrients for the meal and updates the daily intake.
