The Holiday Coffee Drinks That Will Help — or Ruin — Your Diet Slideshow

Slide 1 of 11
Worst Drink at Starbucks: Eggnog Latte

Look, we feel your pain: we know you can’t resist that eggnog-espresso combination, with the steamed milk and ground nutmeg on top. But the Grande size with whole milk has nearly as many calories as a Big Mac (at 550 calories) with 470 calories — and 22 grams of fat. Even the Tall version with nonfat milk has 350 calories and 15 grams of fat. Note to self: Eggnog is the source of trouble this holiday season.
