Late-night eating is linked to circadian rhythm disruption, metabolic conditions, sleep disturbances, and mood disorders
The abstract reports that late-night eating is associated with circadian rhythm disruption, metabolic conditions such as metabolic syndrome, obesity, and type 2 diabetes, as well as sleep disturbances and mood disorders including depression and anxiety. However, the true magnitude of this effect remains unclear, and no systematic review has specifically evaluated the effects of dinner timing and energy intake on these outcomes.

Late-night eating is linked to circadian rhythm disruption, metabolic conditions, sleep disturbances, and mood disorders The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
Late-night eating is linked to circadian rhythm disruption, metabolic conditions, sleep disturbances, and mood disorders
This conclusion is most relevant to: Adults aged 18 to 65 years.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Impact of dinner timing and energy intake on metabolic and mental health: a systematic review protocol. (JBI evidence synthesis, 2026) —
How It Works
The proposed biological pathway:
- ▸Late-night eating disrupts circadian rhythms
- ▸Circadian disruption alters metabolic processes
- ▸Metabolic dysregulation contributes to conditions like obesity and insulin resistance
- ▸Result: Increased risk of metabolic syndrome, sleep disturbances, and mood disorders
Who Might Benefit
Evidence fit by population:
- ▸Adults aged 18 to 65 years
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸The abstract describes a protocol, not results, so no empirical effect sizes or definitive conclusions are provided
- ▸The review only includes RCTs from 2010 onwards, potentially excluding older relevant studies
Frequently Asked Questions
What is the main focus of this systematic review?▼
The review aims to appraise and synthesize randomized controlled trials examining the effects of dinner timing (late vs early) and energy intake (high vs low) on both mental and metabolic health.
What health outcomes are being investigated?▼
Metabolic outcomes such as glucose levels, body weight gain/loss, and insulin resistance, as well as mental health outcomes including mood, sleep quality, anxiety, and depression.
What is the proposed mechanism linking late-night eating to poor health?▼
Late-night eating is thought to disrupt circadian rhythms, which can lead to metabolic dysregulation and contribute to conditions like obesity, type 2 diabetes, sleep disturbances, and mood disorders.
What type of studies will be included in this review?▼
Only randomized controlled trials (RCTs) published from 2010 onwards, involving adults aged 18 to 65 years, that compare early vs late dinner timing and/or low- vs high-energy intake at the last meal of the day.
