10 Worst Fast-Food Desserts on the Planet, According to Dietitians

Chances are if you're heading to a fast-food restaurant to grab a dessert, you're not doing it with the intention of choosing something healthy. There's nothing wrong with treating yourself to your favorite sweet treats from time to time. But if you're someone who frequents fast-food joints quite often and loves finishing your meal out with a dessert, you may want to know which ones are decent in the nutrition department, and which ones experts consider to be the worst fast-food desserts on the planet.

But first, what are some of the things you can look for when trying to choose a dessert that may not totally derail your health goals? For one, you'll want to take note of the total fat and saturated fat. In some dessert options, especially milkshakes and frozen custards, the saturated fat can sometimes go well beyond the daily limit of around 13 grams. Another thing to take note of is how much sugar a dessert has. Of course any sweet treat is going to have sugar, but some fast-food options have upwards of five or six times the recommended daily maximum.

To help you next time you're faced with the decision of which sweet treat you want to grab and take on the go, here's a dietitian-recommended list of the 10 worst fast-food desserts that you'll definitely want to avoid.

Burger King Chocolate Oreo Shake

If you're heading to Burger King, you may want to skip their Chocolate Oreo Shake.

"With 674 calories and 91 grams of sugar, this oreo cookie shake is more than a dessert, it's likely more calories than what a meal should be for most people," says Amy Goodson, MS, RD, CSSD, LD, author of The Sports Nutrition Playbook and member of our Medical Expert Board. "Just to give you an idea, 91 grams of sugar is a little more than one-third of a cup, which is WAY more than what you should have," she adds. "In fact, The American Heart Association (AHA) recommends a max of 9 teaspoons of sugar (36 grams) for men and 6 teaspoons (25 grams) for women."

Sonic 5-Piece Cinnabon Cinnasticks

The Cinnabon Cinnasticks are certainly tempting. However, these "warm, buttery pastries filled with gooey cinnamon roll filling and served with real cream cheese frosting can get you in a calorie bind real quick," says Goodson. "And with 780 calories and 47 grams of fat, this Cinnabon dessert provides more fat than most people should eat in one meal."6254a4d1642c605c54bf1cab17d50f1e

White Castle Fudge-Dipped Brownie on a Stick

It's easy to see the hype surrounding this rich chocolate brownie that you can take on the go, but the amount of sugar is already getting close to your daily recommended limit.

"With 240 calories and 26 grams of sugar, 40% of the total calories of this fudge-dipped brownie on a stick dessert comes from sugar," says Goodson. "While lower in calories, it also has 12 grams of fat, which is 45% of the total calories and means that 85% of this dessert's calories comes from sugar and fat."

Dairy Queen Brownie Dough Blizzard

Of course you'll want to order one of the famous Blizzards if you stop at Dairy Queen, but it may be helpful to note that this dessert is packed full with more saturated fat and sugar than is recommended to eat in a day.

"Made with brownie dough, chocolate chunks, and cocoa fudge blended with the world-famous soft serve to Blizzard^® Treat ice cream, this dessert packs 1,400 calories, 150 grams of sugar, and 32 grams of saturated fat," says Goodson. "Considering the general Daily Value calorie recommendation is 2000 calories a day, this dessert is 70% of the total calories you should eat in a day!"

Additionally, the AHA recommends somewhere around 13 grams of saturated fat per day. That means this dessert almost three times the limit.

Arby's Jamocha Shake

Arby's has more than just their famous curly fries. If you're in the mood for something sweet, you can choose from their collection of delicious shakes. Unfortunately, these shakes, like most fast-food milkshakes, are loaded with calories, sugar, and fat.

"This 'frosty, chocolatey, coffee-y treat' packs 700 calories, 97 grams of sugar, and 13 grams of saturated fat," says Goodson. "So while it might taste good and give you a little caffeine-fix, this shake may be one to leave behind, or at least enjoyed in a smaller size."

Shake Shack Cookies & Cream Shake

According to Lisa Young, PhD, RDN, author of Finally Full, Finally Slim and member of our Medical Expert Board, milkshakes are almost always going to be "high in sugar and calories." The Cookies and Cream Shake at Shake Shack are no exception, with 86 grams of sugar and more calories than most people eat in an entire meal.

McDonald's M&M's McFlurry

Young also adds the McDonald's M&M McFlurry to her list of worst fast-food desserts. "These are big, caloric, and full of fat (including artery clogging saturated fat), as well as tons of added sugar," she explains.

In fact, Young recommends staying away from most of these ice cream and/or custard types of desserts. "They often feature candy, chocolate, and other toppings that pack on calories," she says.

The Best & Worst Menu Items at McDonald's, According to RDs

Dunkin' Frozen Chocolate

The sodium and fat in the Dunkin' Frozen Chocolate may be lower than some of the other desserts on this list. But this drink deals a whopping 158 grams of sugar in one large size, which is over four times the daily recommended sugar limit for men and six times the limit suggested for women.

A&W M&M Polar Swirl

The M&M Polar Swirl from A&W may taste delicious and satisfy your sweet cravings. However, with a whopping 162 grams of sugar, this is certainly one of the worst fast-food desserts out there. Along with having almost 6 times the recommended amount of sugar for an entire day, this ice cream dessert also has twice the recommended saturated fat.

Culver's Chocolate Concrete Mixed With Reese's

With over 1,440 calories, almost 40 grams of saturated fat, and 144 grams of sugar, you may be better off skipping this concrete mixer from Culver's. In fact, you could eat two entire pints of Chocolate Häagen-Dazs ice cream and still not consume as much sugar as there is in a large Culver's concrete mixer.
