This is the science-forward companion to the Sleep and Diet Repair Protocol. It explains why evening food timing and sleep structure make fasting and repair work better.

Sleep is not empty time. It is a biological maintenance window.
Digestion Competes With Repair
Large late meals keep blood flow, heat, stomach activity, and glucose handling active when the body should be shifting into repair. This can interfere with sleep depth, reflux control, overnight glucose rhythm, and the fasting window.
Earlier eating gives the body more time to digest before deep sleep.
Growth Hormone and Tissue Repair
Deep sleep is associated with growth hormone pulses that support tissue repair, lean-mass preservation, and recovery. If sleep is fragmented, the repair signal is weaker.
This is one reason late-night stimulation and heavy digestion matter: they can reduce the quality of the repair window even if total time in bed looks acceptable.
Glymphatic Cleanup
During sleep, the brain's cleanup system becomes more active. This glymphatic process helps clear metabolic waste products from the brain.
Sleep timing, sleep depth, and nervous-system calm are therefore part of the body's cleanup economy.
Circadian Metabolism
The body handles food differently across the day. Late eating often occurs when insulin sensitivity, digestive rhythm, and activity level are lower.
The protocol protects a cleaner relationship between light, food, movement, and rest.
Science-Honest Summary
Sleep repair is the foundation under fasting, insulin discipline, appetite control, autophagy support, and emotional regulation.
The Health Sovereignty sequence begins at night because the next day is built while the body is asleep.
