AKT

dephosphorylates IκB to promote nuclear exclusion, while activating RAS to

target p53 for degradation.

ZIP1

imports zinc to activate ATP citrate lyase directly, accelerating de novo

lipogenesis.

ZIP1 imports zinc to inhibit aconitase

conversion of citrate, promoting citrate accumulation.

~4 mol ATP/mol glucose; MCT4 mediates lactate

efflux from glycolytic cells, whereas MCT1 mediates lactate influx into

oxidative cells for utilisation.

~30

mol ATP/mol glucose; MCT4 imports glutamine while MCT1 exports pyruvate.

~36

mol ATP/mol glucose; MCT1 exports lactate from hypoxic cells while MCT4 imports

lactate into oxygenated cells.

~2

mol ATP/mol glucose; MCT1 and MCT4 both exclusively export lactate to

hyper-acidify the extracellular matrix.

Conversion

to oxaloacetate; GLUT12

Conversion

to citrate; ASCT2

Upper

airway collapse directly suppresses pituitary TSH secretion, lowering basal

body temperature by 3.0 deg C.

Nocturnal

hypoxia destroys pancreatic beta cells, preventing insulin release and trapping

fat in blood vessels.

Sleep

fragmentation and short sleep induce leptin resistance and elevated ghrelin

while altering dietary choices and energy expenditure dynamics.

Intermittent

hypercapnia triggers irreversible hepatic steatosis through cortisol

suppression.

Circadian

misalignment alters food preference, increasing overall snacking with a

specific shift toward high-fat and high-calorie foods.

Night

shifts increase protein oxidation, inducing cravings exclusively for low-fat

dairy products.

Circadian

disruption selectively increases energy expenditure for fat, forcing a

compensatory preference for pure protein.

Shiftwork

leads to selective carbohydrate aversion and increased intake of unsweetened

fluids.

The

master clock causes irreversible mutation of peripheral metabolic enzymes

within 48 hours.

Gastrointestinal

transit time slows to zero, causing hyper-absorption of dietary lipids.

An

internal desynchrony occurs due to a phase mismatch between central sleep/wake

cycles, peripheral fasting/feeding cycles, and tissue metabolic cycles.

Central

circadian clocks in the hypothalamus completely halt peripheral insulin

receptor synthesis.

Destruction

of pancreatic islet tissue caused directly by circulating ghrelin spikes.

Cessation

of hepatic gluconeogenesis, elevated leptin activity, and reduced nocturnal

epinephrine release.

Decreased

brain glucose utilization, elevated nocturnal cortisol and growth hormone (GH),

and suppressed insulin secretion secondary to sympathetic activation.

Increased central glucose clearance, suppressed

cortisol rhythms, and beta-cell hyper-responsiveness.

Adults

require 6 to 8 hours per night; sleeping over 9 hours is universally

recommended for cognitive restoration.

Adults

require 5 to 7 hours per night; sleeping over 9 hours is proven to eliminate

insulin resistance.

Adults

should sleep 7 or more hours per night on a regular basis; sleeping over 9

hours may be appropriate for young adults or those recovering from sleep debt,

but otherwise its health risk is uncertain.

Adults

require exactly 8 hours per night; sleeping over 9 hours increases

cardiovascular mortality by 50% in all populations.
