Hormonal

Sleep restriction increases the appeal of sweet/dessert foods and activates the endocannabinoid system (2-AG), driving hedonic food intake and obesity risk.

If you are sleep-deprived, you are biologically wired to crave sweets. Recognize this as a hormonal response, not a lack of willpower, and plan your snacks accordingly.
