When tiredness sparks your hunger but you’ve had all the calories you need for a while, try eating peanuts or mixed nuts to suppress your appetite. Cheese also works, at least for that specific purpose. The fat in those foods acts as an appetite satisfier. Nuts and cheese have lots of calories, but you’ll find that suppressing your appetite at the expense of some extra calories is still a net gain if the alternative is to eat until everything in your kitchen is gone.
