The Claim

Ingesting carbohydrate with water after exercise provides a smaller performance benefit when athletes have consumed a meal 2–4 hours before the initial exercise bout, compared to when they perform exercise in a fasted state.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

If athletes eat a meal a few hours before working out, drinking carbs with water afterward doesn’t help their recovery as much as it does when they hadn’t eaten beforehand.

The performance benefit of ingesting carbohydrate with water after exercise is reduced when athletes consume a meal 2–4 hours before the initial exercise bout, compared to when they are fasted prior to exercise.

What the research says

1 study

  1. Study: Post-exercise Ingestion of Carbohydrate, Protein and Water: A Systematic Review and Meta-analysis for Effects on Subsequent Athletic Performance

    The study found that carbs after exercise help performance less if you ate a meal a few hours before, compared to if you were fasting. This matches the claim.
