a3km001-star/MetaMeal-AI ? reverse-engineered prompt

Build me a full web app for an AI nutrition and fitness coach called MetaMeal AI.

I want a simple React front end where people can sign up, log in, and then get meal and workout suggestions based on their goals. After that, they should be able to track progress over time, save what they did, and chat with an AI coach for follow up advice and motivation. Make it feel clean and easy to use, with a modern dashboard for the main actions.

Use a Python backend with an API, and store users, plans, and progress in a database. The app should connect the front end to the backend, handle authentication properly, and support generating AI responses for meals, workouts, and chat. If you need to check current docs for anything, go ahead and look them up online. Please set it up so it can run locally with separate client and server folders.
