Sleep and Weight Loss — The Missing Link Most Diets Ignore

Sleeping under 6 hours a night raises ghrelin (hunger hormone), lowers leptin (fullness hormone) and drives cortisol up by 30–40%. Result: you crave sugar all day, store fat around the belly and can't lose weight even in a calorie deficit.

Fix your sleep and your body responds to your diet again — often within 2 weeks.

• Fixed lights-out and wake-up time, even on weekends (±30 min).
• Last meal 3 hours before bed — digestion competes with sleep.
• No phone / laptop 45 min before bed. Kindle or book is fine.
• Bedroom 22–24°C, blackout curtains, phone on silent and face-down.
• 5 min of slow breathing (4 in, 6 out) in bed.
• No caffeine after 2 pm — it has a 6–8 hour half-life.
• Morning sunlight within 30 min of waking — anchors your body clock.

7–8 hours in bed, falling asleep in under 20 min, waking once or not at all, feeling clear-headed by 9 am without coffee. If you're not there yet, pick 3 steps above and start tonight.
