EvidenceModerate

Moderate evidence. Time-restricted eating research is active and promising but not yet definitive. Front-loading calories has some support from circadian biology.

Overview

Align your eating window with daylight hours and front-load calories earlier in the day. Consuming the majority of calories in the first half of the day aligns with circadian insulin sensitivity patterns.

Wellness education and routine support only. Review the evidence, caveats, and interactions before trying this protocol, and ask a clinician when medical conditions, pregnancy, medications, or symptoms are involved.

How To Do It

  1. 1

    Set an eating window

    8-12 hours aligned with daylight. Example: 8am-6pm.

  2. 2

    Front-load calories

    Make breakfast and lunch your larger meals.

  3. 3

    Stop eating 2-3 hours before bed

    Late meals impair sleep quality and glucose regulation.

The Evidence

Each claim is linked to its source study. Confidence reflects the study design — systematic reviews and RCTs rank highest.

Earlier eating windows improved metabolic markers independent of weight loss.
