Add “great sleep” to your laundry list of diet tricks! Researchers analyzed brain scans of 12 men as they looked at images of food, after they had adequate sleep or no sleep.

The group that was starved of sleep felt hungrier than the well-rested, even though their bodies didn’t need the food. Why? Losing your precious z’s activates the part of your brain that triggers hunger.

In other words, when you don’t clock enough hours, your brain is more likely to say “yes!” to more sizzling, cheesy pizza (even when your body says you’ve had enough!). Start calling it a night early and you’ll curb your cravings next time pizza night rolls around.
