Here are the top 5…
Baskin-Robbins Ice Cream Soda (vanilla ice cream and cola) (large, 28.6 fl oz)
960 calories
40 g fat (25 g saturated, 1.5 g trans)
136 g sugars
Sugar Equivalent: 9.7 Fudgsicle fudge bars
Done right, an ice cream float can be a decent route to indulgence. Go to A&W and you’ll land a medium for fewer than 400 calories. Order it with diet soda and you’ve dropped below 200 calories. So why can’t Baskin-Robbins make even a small float with fewer than 470 calories? Because apparently the chain approaches the art of beverage-crafting as a challenge to squeeze in as much fat and sugar as possible. Whatever you order, plan on splitting it with a friend.
Krispy Kreme Lemon Sherbet Chiller (20 fl oz)
980 calories
40 g fat (36 g saturated)
115 g sugars
Sugar Equivalent: 16 medium-size chocolate eclairs
Imagine taking a regular can of soda, pouring in 18 extra teaspoons of sugar, and then swirling in half a cup of heavy cream. Nutritionally speaking, that’s exactly what this is, which is how it manages to marry nearly 2 days’ worth of saturated fat with enough sugar to leave you with a serious sucrose hangover. Do your heart a favor and avoid any of Krispy Kreme’s “Kremey” beverages. The basic Chillers aren’t the safest of sippables either, but they’ll save you up to 880 calories.
McDonald’s Triple Thick Chocolate Shake (large, 32 fl oz)
1,160 calories
27 g fat (16 g saturated, 2 g trans)
168 g sugars
Sugar Equivalent: 13 McDonald’s Baked Hot Apple Pies
There are very few milk shakes in America worthy of your hard-earned calories, but few will punish you as thoroughly as this Mickey D’s drive-thru disaster. Not only does it have more than half your day’s caloric and saturated fat allotment and more sugar than you’d find in Willy Wonka’s candy lab, but Ronald even finds a way to sneak in a full day of cholesterol-spiking trans fat. The scariest part about this drink is that it’s most likely America’s most popular milk shake.
2. Worst Smoothie
Smoothie King Peanut Power Plus Grape (large, 40 fl oz)
1,498 calories
44 g fat (8 g saturated)
214 g sugars
Sugar Equivalent: 20 Reese’s Peanut Butter Cups
If Smoothie King wants someone to blame for landing this high on our worst beverages roundup (and truth be told, its entire menu is riddled with contenders), the chain should point the smoothie straw at whichever executive came up with the cup-sizing structure. Sending someone out the door with a 40-ounce cup should be a criminal offense. Who really needs a third of a gallon of sweetened peanut butter blended with grape juice, milk, and bananas? Sugar-and-fat-loaded smoothies like this should be served from 12-ounce cups, not mini kegs.
Cold Stone PB&C (Gotta Have It size, 24 fl oz)
2,010 calories
131 g fat (68 g saturated)
153 g sugars
Sugar Equivalent: 30 Chewy Chips Ahoy Cookies
In terms of saturated fat, drinking this Cold Stone catastrophe is like slurping up 68 strips of bacon. Health experts recommend capping your saturated fat intake at about 20 grams per day, yet this beverage packs more than three times that into a cup the size of a Chipotle burrito. But here’s what’s worse: No regular shake at Cold Stone, no matter what the size, has fewer than 1,000 calories. If you must drink your ice cream, make it one of the creamery’s “Sinless” options. Otherwise you’d better plan on buying some bigger pants on the way home.
