We all like to splurge on a decadent dessert every now and again. But do you know how decadent you're actually being? See if you can guess how many calories are in these restaurant favorites and rank them from lowest to highest.
  1. Tiramisu, Au Bon Pain (one slice) - 310 calories. This Italian favorite was the best choice. It also has 15 grams of fat (8 saturated), 39 carbohydrate grams, and 7 protein grams.
  2. Apple Pie, Denny's (one slice) - 470 calories. It's as American as the obesity crisis! It also has 24 grams of fat (6 saturated), 64 grams of carbs, and 6 protein grams. Not bad, but once you add that scoop of vanilla ice cream, you're moving into the danger zone.
  3. Original Cheesecake, The Cheesecake Factory (one slice) - 500 calories. Its calorie count is up there, but check out the fat content: 36 grams (16 saturated). You won't be posing for any cheesecake photos if you top off your meal with this. It also gives you 42 carb grams and 9 grams of protein.
  4. Chocolate Chip Cookie Dough Blizzard, Dairy Queen (large) - 1,320 calories. Now we're talking some serious diet damage. With 52 grams of fat (26 saturated), 193 grams of carbs, and 21 grams of protein, you've pretty much wrecked your diet—especially if you're using the shake to wash down your burger and fries.
  5. Chocolate Mother Lode Cake, Claim Jumper (1 slice) - 3,120 calories. This truly is the mother of all loads. This six-layer masterpiece of artery-clogging mayhem weighs almost 3 pounds, and also has 162 grams of fat (almost 3 days' worth), 42 grams of which are saturated and 18 grams of which are trans. It also has 438 grams of carbs and 48 grams of protein. If you're seriously considering "death by chocolate," this is a good place to start.
