Sleep is the part of a diet nobody logs. These guides cover what the research shows about short sleep and appetite hormones, how caffeine timing and alcohol change sleep quality, and practical fixes for late eaters and shift workers.
Alcohol does not help you sleep, it sedates you and breaks the rest. Deep sleep loss, REM suppression, blunted recovery, and the calorie spillover that follows.
Sleep deprivation cuts muscle protein synthesis, recovery and strength. Why sleep is the most underrated training variable, and the targets that protect gains.
Night-shift workers gain weight on the same calorie intake as day workers. The reason is circadian, not behavioral. The mechanism and a shift-week playbook.
A bedroom at 18 to 19C improves sleep quality and activates brown fat enough to nudge metabolism. The science of cool sleep and the practical setup that gets you there.
Two nights of 4-hour sleep drops leptin 18% and raises ghrelin 28%. Here is what those hormones actually do, why cravings spike for specific foods, and how to reset them.
Eating close to bedtime does not directly cause weight gain, but it lowers sleep quality through reflux, core temperature and glucose. The practical window.
Caffeine has a 5 to 6 hour half-life, so a 3 PM coffee leaves you with a quarter of the dose at midnight. Here is the science of the cutoff time, and how to set yours.
Short sleep raises calorie intake by 250 to 385 kcal a day, breaks the leptin to ghrelin ratio, and stalls fat loss at the same calorie target. The evidence.
