Bad sleep undermines GLP-1 results faster than most people realise. The mechanism and the fix.
Why sleep matters
Poor sleep raises cortisol, which increases appetite and abdominal fat storage. It also disrupts the hormones (leptin, ghrelin) that GLP-1 is amplifying. 6 hours = your medication is working with one hand tied behind its back.
Target
7–9 hours, consistent timing (within 30 min of the same bedtime), dark room, cool temperature (24°C max).
Sleep blockers to fix
Late caffeine (after 2 pm), late meals (close to bedtime), screens in bed, alcohol within 3 hours of sleep, untreated reflux.
