If you do only one thing to lose or maintain weight, let it be this—reduce your portion size by about one-third per meal and, over time, you’ll lose weight without feeling ravenous. You don’t have to change what you eat or “diet” in any other way. The simple fact is that when you eat less, you lose weight.

Brushing your teeth in the afternoon is a great way to curb your appetite. First, your mouth feels good and clean—so much so that you’re less apt to dirty it up anytime soon. Second, the minty flavor of some toothpastes can actually reduce your craving for another flavor. Bonus: When you wake up your mouth, you feel more alert!
