04 / What This Publication Covers

Sleep Architecture

Analysis of sleep stage distribution and its documented association with next-day energy balance, appetite signalling, and portion awareness across tracked client cohorts.

Circadian Rhythm

Field-sourced notes on circadian timing, wake rhythm consistency, and how the body's internal scheduling system intersects with metabolic rate and appetite circadian signal activity.

Body Composition

Long-term tracking data on the relationship between rest quality, gradual progress, and sustainable body composition outcomes — approached through a slow-change methodology.

Portion Awareness

Practical documentation of how portion selection shifts in response to sleep duration, identified through structured check-in cadence and accountability rhythm protocols.

Evening Routines

Documented evening protocols drawn from session notes, covering the bedtime window, meal timing, light exposure, and movement patterns that precede restorative sleep.

Editorial Standards

All published content is reviewed against peer-reviewed nutrition research and published sleep studies. Sources are cited, corrections noted publicly, and editorial conflicts disclosed.

05 / Editorial Position
"Rest is not a variable to be optimised around. It is the substrate on which all other habit formation operates."

Dorex Letters operates on the principle that sustainable weight management cannot be separated from sleep quality and consistency. This publication documents that relationship through field observation, published research review, and long-term client pattern analysis.
