This project introduces FitFeast, an intelligent health and nutrition application designed to provide personalized diet planning and wellness guidance using AI-driven insights. The system goes beyond traditional calorie tracking applications by integrating Body Mass Index (BMI) analysis, dietary preference customization, allergy-aware filtering, and adaptive meal recom- mendations into a unified platform. At its core, FitFeast evaluates user-specific parameters such as height, weight, age, and gender to determine optimal health metrics and caloric requirements. Based on these inputs, the system generates a balanced, nutrient- rich diet plan tailored to individual goals such as weight loss, maintenance, or weight gain. The application further enhances user experience through a dynamic food substitution mecha- nism, allowing users to replace meals with equivalent calorie alternatives while maintaining nutritional balance. A dedicated knowledge wall provides insights into food properties, calorie val- ues, and health precautions, ensuring informed dietary decisions. Additionally, FitFeast integrates a dietician consultation module, enabling users to book certified professionals for expert guidance. The inclusion of a physical activity section promotes holistic wellness by educating users on exercises such as walking, Zumba, gym workouts, and sports. Overall, the system aims to deliver a comprehensive, user-centric, and intelligent health management solution, promoting sustainable lifestyle improvements through personalized nutrition and fitness planning.
