Meal Timing & Circadian Nutrition
Eat most calories earlier in the day when insulin sensitivity is highest. Avoid large meals within 2-3 hours of bedtime for better metabolic health and sleep.
Dosage & Timing
Evidence Strength
3/5 — ModerateModerate 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.
How To Do It
Set an eating window
8-12 hours aligned with daylight. Example: 8am-6pm.
Front-load calories
Make breakfast and lunch your larger meals.
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.
Early time-restricted feeding improves insulin sensitivity, blood pressure, and oxidative stress↗
Earlier eating windows improved metabolic markers independent of weight loss.

Measurable Outcomes
Related Protocols
Time-Restricted Eating (16:8)
Eat within an 8-hour daily window (e.g., 10 AM–6 PM). 16 hours of fasting improves insulin sensitivity, supports autophagy, and aligns eating with circadian metabolic peaks.
Post-Meal Walking
A 10-20 minute easy walk after meals can reduce post-meal glucose spikes and improve glycemic control. It is low-cost, scalable, and useful even for users who already train formally.
Omega-3 Intake (EPA+DHA)
Get 2-4g EPA+DHA daily through fatty fish or supplements. Critical for inflammation management, brain health, and cardiovascular protection.
Fermented Foods for Gut Health
2-3 servings of fermented foods daily to boost gut microbiome diversity. Stanford research showed this increased microbial diversity and reduced inflammatory markers.
