AI Fitness Coaching & Personalized Nutrition Mobile App

About AI Fitness Coaching & Nutrition Platform

The AI Fitness Coaching & Nutrition Platform is a custom mobile application developed to provide personalized fitness guidance, nutrition recommendations, meal planning, and recipe generation. Instead of relying on generic workout routines and fixed diet plans, the application uses artificial intelligence to deliver suggestions based on individual fitness goals, body measurements, exercise experience, dietary preferences, and lifestyle information. It combines a conversational AI Fitness Coach with an intelligent nutrition planning system, helping users access fitness and meal-related guidance through one mobile experience.

Built using OpenAI APIs and Retrieval-Augmented Generation (RAG), the platform connects conversational AI with a curated fitness and nutrition knowledge base. Users can ask questions about workouts, training, recovery, nutrition, and personal goals while receiving responses informed by relevant profile details and previous conversations. Vector-based semantic search retrieves useful information from the knowledge base before the AI generates an answer. Selective context retrieval also helps maintain conversation continuity while reducing unnecessary AI token usage and improving the relevance of responses.

The platform includes an AI Meal Planner and Recipe Generator that supports weight loss, muscle gain, body recomposition, and maintenance goals. It calculates personalized calorie and macronutrient targets before generating meal recommendations based on dietary preferences, food restrictions, and taste choices. Developed with React Native, Node.js, Supabase, and OpenAI technologies, the application brings fitness coaching and nutrition planning together in a connected system. This project demonstrates how AI and machine learning development can support more personalized and context-aware health and wellness applications.
