Sleep and Weight
Why short or broken sleep raises hunger hormones and sabotages loss — and what treatment-era sleep hygiene looks like.
Sleep restriction is pharmacologically unfair: even a few short nights raise ghrelin, lower leptin, sharpen reward response to junk food, and worsen insulin sensitivity — a stacked deck against any deficit, which controlled studies confirm by showing dieters losing less fat when sleep-deprived at equal calories.
Weight loss repays the favor in reverse: it improves sleep apnea, reflux, and joint pain that fragment nights. The treatment-era basics are familiar but newly consequential — consistent schedule, dark cool room, caffeine curfew, screens out of the last hour — plus one medication-specific note: taking evening doses of anything that upsets your stomach earlier can protect the night. Chronic loud snoring with daytime exhaustion still warrants an apnea evaluation, medication or not.
