+A nutrition tracking app focused on **behavior change**, not just calorie counting.
+
+The system helps users:
+- understand their eating patterns  
+- receive structured feedback  
+- improve habits through measurable adjustments  
+
+Core principle:  
+**log → see → understand → adjust**
+
+---
+
+## 🎯 Project Goals
+
+### 1. Motivation for Behavior Change
+Help users improve eating habits through clear feedback  
+
+### 2. Motivation for Behavior Maintenance
+Support consistency via simple daily evaluation  
+
+---
+
+## 🧠 Motivation Tools
+
+### Awareness through Data
+- Users see actual intake vs goals  
+
+### Scoring System
+- Daily score: **1–10**  
+- Based on deviation from goals  
+- Simplifies complex nutrition data  
+
+---
+
+## ⚙️ Usage Configuration
+
+The system allows users to:
+- Select which parameters to track  
+- Define their own target values  
+
+---
+
+## 🧭 Recommended Tracking Approaches
+
+### Beginner Approach
+- Calories  
+- Protein  
+- Fat  
+- Carbohydrates  
+
+### Full Tracking Approach
+- Calories  
+- Protein  
+- Fat  
+- Carbohydrates  
+- Water  
+- Caffeine  
+- Alcohol  
+
+### Goal-Oriented Tracking
+
+Examples:
+- Alcohol reduction → track alcohol only  
+- Hydration improvement → track water  
+
+If unsure, start with the Beginner Approach and expand later.
+
+---
+
+## 🎯 Goal Setting
+
+Users define their own targets for each parameter.
+
+---
+
+## 🔄 User Flow
+
+1. Registration  
+2. Profile setup  
+3. Meal logging  
+4. Aggregation  
+5. AI evaluation  
+6. Daily report  
+
+---
+
+## 🧠 Core Logic
+
+**Log → Aggregate → Evaluate → Recommend → Adjust**
+
+---
+
+## 🧩 Features
+
+- Food logging  
+- Macro & extended tracking  
+- Daily scoring  
+- AI-generated feedback  
+- Personalized recommendations  
+
