Of course, those cool coffee drinks aren't much better. Talk about putting a major dent in your dieting efforts. A 16-ounce Mocha Frappuccino Blended Coffee from Starbucks has 380 calories, 15 grams of fat and 47 grams of sugar. Not one to be outdone, the Peppermint Mocha Frappucino Blended Coffee with whipped cream has 470 calories, 17 grams of fat and 68 grams of sugar. Fancy tea drinks might seem like a much better option, but even those can cost you. An Apple Chai Infusion from Starbucks has 320 calories and 74 sugars, while the Iced Tazo Green Tea Latte has 270 calories, 5 grams of fat and 43 grams of sugar. Basically, your best bet is to stick with the basics and leave out all of the costly extras.
