6. Artificially Sweetened Drinks

Goodbye, diet soda, and every other sweet-tasting drink that mysteriously contains zero calories! "There are some people whose brains are wired in a way that artificial sweeteners induce or enhance cravings," says Dr. Seltzer. "If drinking a Diet Snapple leads you to the Ben & Jerry's, then you'd certainly be better off with water or water with lemon." Or sparkling water: It's calorie-free, but carbonated, which makes your stomach feel full so you end up eating less overall.
