Claim: If you don’t drink while you eat, you’ll lose weight. This couldn’t be more false. “If you’re drinking while you’re eating, you’re going to slow down and eat fewer calories,” says registered dietitian Keri Glassman. Bottom line: Drink up!

Claim: Snacking is good for you. You may think you’re doing some good by starving yourself in between meals, but Keri explains that “snacking keeps your metabolism revved, blood sugar levels stable and your energy up.” Not to mention it prevents you from pigging out at the first sign of food!
