Beyond Simple Image Recognition: Building a Precise AI Nutritionist with GPT-4o and Segment Anything (SAM)

We've all been there: you take a photo of your lunch with a generic calorie-tracking app, and it tells you your 500-gram lasagna is a "medium slice of cake." 🤦‍♂️ The struggle with AI nutrition tracking isn't just identifying the food; it's the spatial awareness—understanding volume, portion size, and the hidden ingredients in complex dishes. In this tutorial, we are leveling up. We are building a sophisticated Visual RAG (Retrieval-Augmented Generation) pipeline. By combining the semantic powe
