## TL;DR

Athlete nutrition should match training load, sport demands, and recovery needs. This repair removes precise timing and supplement claims unless directly tied to consensus or position statements.

## Core Explanation

The bounded summary is that nutrition plans for athletes are individualized, carbohydrate availability matters for many training contexts, protein recommendations for active people are higher than sedentary baseline needs, and fluid replacement is planned around losses and conditions.
