Shakes and Frozen Treats Top the Charts
When considering what is the most unhealthy item at Sonic, the dessert menu is a frequent starting point. Many of Sonic's large shakes and ice cream-based treats pack a staggering number of calories, saturated fat, and sugar into a single serving. These indulgent options, while popular, contribute heavily to a day's worth of dietary allowances in one sitting.
The Sonic Peanut Butter Fudge Malt
One historical contender for the most unhealthy item was the large Peanut Butter Fudge Malt. A 2017 report cited this shake as containing a massive 123 grams of fat and thousands of calories. While recipes may change, this item illustrates the potential for extreme unhealthiness within the dessert category. These shakes combine high-fat ice cream with sugary syrups, fatty peanut butter, and toppings, creating a perfect storm of excess calories and saturated fat.
Large Shakes Remain a Major Concern
Even with menu variations over the years, large Master Shakes are consistently among the most calorie-dense items. The Oreo Peanut Butter Master Shake, for instance, has been documented to contain over 1,700 calories in a large size, along with high levels of saturated fat and added sugar. This is a prime example of how these blended treats can easily exceed the calorie count of a full, multi-course meal from other establishments.
Decadent Burgers and Combos
Beyond the dessert counter, several savory items also vie for the title of the most unhealthy item at Sonic. Burgers, especially those featuring multiple patties, bacon, and mayonnaise, are known for their high sodium and fat content.
The Supersonic Bacon Double Cheeseburger
This burger is another strong candidate for the most unhealthy menu item, regularly appearing on lists of the worst fast-food options. Commenters on Yahoo have pointed out its high calorie count (1,130 calories) and immense sodium content (2,000 milligrams), noting its disappointing quality as well. The combination of multiple beef patties, fatty bacon, and creamy mayonnaise creates a sandwich that, while seemingly satisfying, is a nutritional nightmare. The small size of the patties mentioned by some customers highlights a potential trade-off between perceived quality and nutritional density.
Customizing for Calorie Spikes
It is also worth noting that customized orders and large combo meals can quickly push the calorie count sky-high. A Tiktok user in 2024 assembled a "Sonic's Unhealthiest Meal Challenge" that combined a large bacon double cheeseburger with large onion rings and a large milkshake, reaching a total of 3,640 calories. This demonstrates how combining individual high-calorie items can result in an extremely unhealthy meal. The addition of sides and drinks, particularly sugary ones like the Route 44 soda, dramatically inflates the nutritional impact.

What Makes These Items So Unhealthy?
Excessive Calories
Many of the unhealthiest items at Sonic, particularly the large shakes and decadent burgers, contain an entire day's or more of recommended calories. A high-calorie meal can contribute to weight gain and increase the risk of various health problems.
High Saturated Fat
Saturated fats, found in high concentrations in dairy-based desserts and fatty meats, are linked to an increased risk of heart disease. The Master Shakes and double cheeseburgers contain significant amounts of this type of fat.
Sky-High Sodium
Processed meats and fried items, like the Bacon Double Cheeseburger and Chili Cheese Tots, are loaded with sodium. Excessive sodium intake can lead to high blood pressure and increase the risk of heart disease.
Added Sugar Overload
Drinks and desserts, such as the shakes and Blasts, contain massive amounts of added sugars, which contribute to weight gain, inflammation, and an increased risk of type 2 diabetes.
How to Enjoy Sonic Responsibly
For those who still want to visit Sonic without completely derailing their diet, there are healthier choices available. Options like ordering from the kids' menu, opting for a regular-sized burger without extra toppings, or choosing water or unsweetened tea instead of sugary sodas can make a significant difference. Being mindful of portion sizes and avoiding high-fat, high-sugar additions is key to enjoying fast food in moderation.

Conclusion
While identifying a single definitive item as the absolute worst can be challenging due to menu changes and customization, the evidence consistently points toward Sonic's large, premium dessert options and loaded cheeseburgers as the most unhealthy contenders. Items like the large Oreo Peanut Butter Master Shake and the Supersonic Bacon Double Cheeseburger stand out due to their exceptionally high calorie, saturated fat, and sodium content. These items, along with combo meals featuring large sides, represent the pinnacle of unhealthy fast-food consumption at Sonic. By being aware of these nutritional extremes, customers can make more informed decisions and choose healthier alternatives when visiting the drive-in.
