You already know sleep matters.
What most people don’t know is exactly why a bad night makes you crave carbs, feel hungrier, and make worse decisions the next day, even if nothing else about your diet has changed.
Poor sleep increases ghrelin (your hunger hormone) and decreases leptin (your fullness hormone)
This leaves you hungrier, and less satisfied when you do eat.
It also raises cortisol, which is directly linked to cravings for sugar and carbs specifically, as your body looks for a fast energy fix.
On top of that, the part of your brain responsible for planning and willpower is measurably less effective when you’re sleep deprived.
So if a bad night’s sleep has derailed your day before, that was never a discipline problem. You were working with a stacked deck.
Comment SLEEP and I’ll send you the full guide, outlining exactly what to do differently on the days you know a good night’s sleep just isn’t happening.
