Have you had a Starbucks Frappuccino lately? Or an iced mocha or latte? If so, you may have downed more than 300 calories, depending on the size of your drink, the type of milk and syrup you chose and whether you said yes to whipped cream. “We’ve turned coffee into a coffee milkshake,” Liebman says. “Many people still have the idea that the calories in coffee drinks don’t count, but whipped cream isn’t free.” In fact, it costs you 80-100 calories.
