The One Hour of Sleep That's Sabotaging Your Weight Loss
If you're sleeping less than seven hours, no diet on earth will fully work. The relationship between sleep and metabolism is brutal — and fixable.
Studies on women over 40 are remarkably consistent: every hour of sleep lost below seven correlates with measurable increases in hunger hormones, cravings, and abdominal fat.
Ghrelin, leptin, and the hungry brain
Sleep deprivation raises ghrelin (the hunger hormone) and lowers leptin (the satiety hormone). The result: you wake up genuinely hungrier and stay that way until you sleep properly again.
The fixable part
Most sleep issues at 40+ trace to three culprits: late caffeine, late screens, and late meals. Caffeine cutoff at 1pm. Screens off 45 minutes before bed. Last bite three hours before bed. Try it for two weeks before changing anything else.
