Summer is here and for most of us that means it's time for iced coffee and other frozen coffee treats! But behind the delicious taste are usually high calories, so here are some of the coffee drinks you may want to avoid this season.

The authors of Eat This Not That have broken down the nutritional information behind some people's favorite frozen summertime drinks. And whether you want to listen to them or not, here is what they say are some of the worst coffee drinks in the country.

    Dunkin' Donuts Frozen Caramel Coffee Coolatta with Cream

    A large one of these coolattas has 990 calories, not to mention 130 grams of sugar. Yikes!

    For that same amount of calories at Dunkin you could wolf down a  Bacon Egg and Cheese on a Croissant, an Oatmeal Raisin Cookie AND a Chocolate-Frosted Donut with Sprinkles!

    Starbucks Whole Milk White Chocolate Mocha with Whipped Cream

    Getting this treat in venti means consuming 620 calories and 75 grams of sugar in just a few sips.

    That's more sugar than you'd get if you ate seven of their chocolate croissants. Crazy!

    McDonald's McCafe Frappe Mocha, No Whip

    Again ordering a large frozen treat really packs on the calories. This drink will have you consuming 600 calories to be exact and 84 grams of sugar.

    The ingredient list for this beverage is a bit questionable too. The book points out the inclusion of polysorbate 80—an emulsifier that also has a reputation for topically stimulating hair grown in men who are going bald.

    Plus there's artificial colors Red 40, Yellow 5 and Blue 1, which makes no sense since any coffee I've ever brewed is brown...

    Krispy Kreme Lotta Latte Chiller

    I'm not sure there's anything "healthy" on the Krispy Kreme menu, but this drink is just crazy.

    Even a small will set you back 670 calories and contains 60 grams on sugar. A small!

    And if you were splurging on a can double that calorie content. Definitely not a drink while on a diet.

    Au Bon Pain Coffee Blast

    This coffee drink is not so much coffee as it is ice cream. Literally. The first ingredient listed is ice cream.

    That may be why the frozen delight is a whopping 690 calories and 112 grams of sugar.

    It also contains more carbs than 9 slices of wonder bread! Definitely not the best beverage out there is your trying to stay in shape this summer.
