abstract = {The growing reliance on digital platforms for health, nutrition, and sports guidance has introduced challenges related to accuracy, privacy, and transparency of information. Most existing solutions depend on cloud-hosted large language models (LLMs) or static rule-based systems, often producing generalized or unverifiable recommendations while retaining user data on external servers. This paper presents Larry, a Retrieval-Augmented Generation (RAG) powered sports and nutrition guidance system designed to operate entirely on a local machine. Larry leverages a curated knowledge base of authoritative books in nutrition, sports science, and general health to generate context-aware, user-specific recommendations. By combining agentic reasoning with vector-based retrieval, the system ensures responses are grounded in verified literature while preserving user privacy. A comparative study is conducted between Larry, a generic LLM without retrieval augmentation, and manual book-based consultation. Evaluation based on accuracy alignment, response consistency, and user satisfaction demonstrates that Larry significantly reduces hallucinated outputs and improves decision support. The results indicate that RAG-based, localhost-deployed systems can serve as effective, privacy-preserving alternatives to cloud-centric health guidance platforms.},
