Pre-Exercise Carbohydrate or Protein Ingestion Influences Substrate Oxidation but Not Performance or Hunger Compared with Cycling in the Fasted State

Randomized Controlled Trial

Human

2021 Apr 14

The study gave cyclists either a carb meal, a protein meal, or nothing before cycling, and found that no matter what they ate (or didn’t eat), they all felt just as hungry during and after the workout. So, what you eat before cycling doesn’t change how hungry you feel.

Whether you eat carbs, protein, or nothing before a hard cycling workout with short bursts of maximum effort, your power output stays the same — your body can still push hard regardless of what you ate beforehand.
