When you’re sleep-deprived, your body undergoes a chemical shift that makes willpower nearly impossible. The science behind it - two specific hormones go haywire:
⏺️ Ghrelin (The "Go" Signal): This hormone tells you when to eat. Lack of sleep spikes ghrelin levels, making you feel perpetually hungry.
⏺️ Leptin (The "Stop" Signal): This hormone tells you when you're full. Sleep deprivation plummets leptin, so your brain never gets the memo that you’ve had enough.
So if you're trying to lose weight and stay healthy, sleep isn't just "down time"—it's actually a metabolic necessity. So make sure you prioritise your sleep.
