Why should nutrition be periodized with training?

A constant caloric intake regardless of training load means under-fueling on hard days (performance and recovery impaired) and over-fueling on easy/rest days (unnecessary fat gain). Matching nutrition to load optimizes both.

How is training load measured?

Internal load can be measured as session-RPE (rate of perceived exertion × session duration) or as heart rate training impulse (TRIMP). External load uses GPS distance, speed, or power meter kilojoules.

What is the practical nutrition periodization approach?

High-carb on high-intensity or long-duration training days. Moderate-carb on moderate-intensity days. Lower-carb on rest or low-intensity days. Protein stays constant at 1.6-2.2 g/kg throughout.
