The post-lunch dip in performance
Monk TH
Published in Clinics in Sports Medicine
Methodology
Review of chronobiological and performance studies documenting the mid-afternoon decline in alertness and performance.
Key Findings
A post-lunch performance dip occurs even without a midday meal, reflecting an endogenous circadian trough that meal composition and size can amplify.
Conclusions
Afternoon energy crashes are primarily circadian in origin, with diet, sleep debt and caffeine timing as modifiable amplifiers.
Limitations
Narrative review; heterogeneous laboratory paradigms; limited real-world data.
Outcomes Measured
The post-lunch dip reflects an endogenous circadian trough rather than the meal alone.
