Later first and last caloric intake timing is independently associated with lower Morningness-Eveningness Questionnaire (MEQ) scores in physically active university students.

In a cross-sectional study of 200 physically active university students, later first and last caloric intake were independently associated with lower MEQ scores (β = -0.435 and -0.422, respectively; both p < 0.001), indicating greater eveningness. The model explained 51.1% of the variance in MEQ scores. Evening-type participants had poorer sleep behaviors, longer sleep latency, lower sleep efficiency, more nocturnal awakenings, and poorer subjective sleep quality compared to morning-type participants.

Later first and last caloric intake timing is independently associated with lower Morningness-Eveningness Questionnaire (MEQ) scores in physically active university students. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).

The Claim

Later first and last caloric intake timing is independently associated with lower Morningness-Eveningness Questionnaire (MEQ) scores in physically active university students.

This conclusion is most relevant to: Physically active university students aged 18-25 years who exercised ≥3 days/week and ≥150 min/week for the preceding six months (n=200)..

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Chronotype, temporal eating patterns, and sleep behaviors among physically active university students: A cross-sectional study. (Chronobiology international, 2026) —

How It Works

The proposed biological pathway:

  • Later first caloric intake may shift circadian phase, delaying the internal clock.
  • Later last caloric intake may affect metabolic signals that influence sleep-wake timing.
  • Evening chronotype is associated with poorer sleep behaviors and sleep quality.
  • Result: Later meal timing is associated with greater eveningness and less favorable sleep characteristics.

Who Might Benefit

Evidence fit by population:

  • Physically active university students aged 18-25 years who exercised ≥3 days/week and ≥150 min/week for the preceding six months (n=200).

Limitations & Caveats

Important context when interpreting this evidence:

  • Cross-sectional design; causality and temporal direction cannot be inferred.
  • Single-university sample limits generalizability to other populations.
  • Dietary intake and sleep were self-reported, potentially introducing recall bias.
  • No adjustment for potential confounders like physical activity intensity or academic schedule.

Frequently Asked Questions

What is the main finding of this study?

Later first and last caloric intake timing is independently associated with lower MEQ scores, indicating a shift toward eveningness, in physically active university students.

How was chronotype measured?

Chronotype was measured using the Morningness-Eveningness Questionnaire (MEQ), with lower scores indicating eveningness.

Did total energy or macronutrient intake affect sleep outcomes?

No, total energy and macronutrient intake were unrelated to the evaluated sleep outcomes.

Can we conclude that eating later causes worse sleep?

No, because the study is cross-sectional, so causality and temporal direction cannot be inferred.
