In many circles, the term “Apple Rule” may be associated with accounting tricks used by tech companies to record sales in real time. But for the purpose of this tip, the term will be used to help those with over-eating issues fight hunger pangs.

It’s one of the most important rules from food journalist and UC Berkeley profressor Michael Pollan’s book, Food Rules: “If you’re not hungry enough to eat an apple, then you’re not hungry.”

Practicing this rule is easier said than done, but with discipline it can be used to effectively cut down on snacking habits while also providing a healthy alternative to your typical vending machine-type snack.

“Eat when you are hungry, not when you are bored,” Pollan says.

Apples are low in calorie, averaging 80 calories when medium-sized, and contain natural sugars and fibers, which can keep your blood sugar stable and provide a full feeling.

They also help fight colds and other illnesses, according to our resident nutrition student, Caitlin Self.

So keep apples handy and the Apple Rule in mind the next time you feel hunger creeping up on you during a study break.
