Burgers are an American comfort classic, but some are a ticking time bomb for your health. While a juicy burger might feel like the ultimate indulgence, certain chain options pack sky-high calories, alarming levels of saturated fat, and sodium loads that rival your daily limit in a single bite. Before you hit the drive-thru, it’s worth knowing which patties are worth skipping if you want to protect your waistline and your heart. We’ve rounded up the 10 unhealthiest burgers you can order from major chains—so you can steer clear and make smarter choices while still satisfying your cravings.
1. Five Guys Cheeseburger

Saturated fat champion! The Five Guys Cheeseburger delivers a whopping 984 calories and 26.5 grams of saturated fat in one sitting. That’s more saturated fat than many people should consume in an entire day.
The sodium content hits 1,050mg, which is nearly half your daily recommended intake. Their hand-formed patties might be fresh, but they’re cooked in liberal amounts of oil that contribute to the sky-high fat content.
What makes this burger particularly concerning is how it tops the charts for saturated fat among all fast-food cheeseburgers, putting it in a league of its own for potential heart health impacts.
2. Whataburger Jalapeño & Cheese Whataburger

Texas-sized trouble comes in the form of this spicy monster. The Jalapeño & Cheese Whataburger earned its second-place ranking due to dangerously high levels of saturated fat and sodium that put serious strain on your cardiovascular system.
While the jalapeños might add a metabolism-boosting kick, any potential benefits are completely overshadowed by the nutritional damage. The combination of multiple cheese slices and special sauce creates a perfect storm of unhealthy fats.
Heart health experts particularly warn against this burger’s fat-sodium combination, which can contribute to elevated blood pressure and increased risk of heart disease when consumed regularly.
3. Smashburger Classic Smash

Don’t let the trendy “smashed” cooking technique fool you. This burger shares the second-place unhealthiness ranking with Whataburger’s offering, packing a serious caloric and saturated fat punch that nutritionists find alarming.
The signature smashing process that creates a caramelized crust actually seals in fats rather than allowing them to cook off. Their special “smash sauce” adds even more unnecessary calories and fat to an already problematic menu item.
Despite its relatively modest appearance compared to some monster burgers, the Classic Smash delivers a surprisingly unhealthy nutritional profile that places it firmly in the top tier of burgers to avoid.
4. Carl’s Jr. Famous Star with Cheese

Nothing famous about these nutrition stats! This burger lands fourth on our list with calorie density and saturated fat levels that exceed what most nutritionists recommend for an entire meal.
The Famous Star combines multiple high-fat ingredients – a charbroiled beef patty, American cheese, and mayo-based Special Sauce – creating a triple threat to your arteries. The burger’s seemingly innocent vegetable toppings barely make a dent in offsetting the nutritional damage.
Particularly troubling is how Carl’s Jr. markets this as one of their “classic” options, potentially misleading customers about just how unhealthy this standard menu item really is.
5. Sonic Cheeseburger

Rolling in at fifth place, Sonic’s seemingly basic cheeseburger hides a nutritional reality that’s anything but simple. The combination of high saturated fat and sodium makes this drive-in favorite particularly problematic for cardiovascular health.
Unlike some competitors who at least offer customization options, Sonic’s standard preparation includes full-fat mayo and processed American cheese that significantly boost the unhealthy fat content.
The toasted bun adds extra calories through oils used in the toasting process. Regular consumption of this deceptively ordinary-looking burger could contribute to elevated cholesterol levels and increased risk of heart disease over time.
6. Checkers/Rally’s Baconzilla Burger

The name says it all – this monster contains a terrifying 1,210 calories, 96g of fat, and 36g of saturated fat. That’s nearly triple the recommended daily saturated fat intake in just one meal!
Two beef patties layered with multiple strips of bacon and two types of cheese create an artery-clogging nightmare. The sodium content hits 2,950mg – more than an entire day’s worth – potentially triggering water retention and elevated blood pressure.
What makes the Baconzilla particularly dangerous is how it’s marketed as an indulgent treat rather than the serious health hazard it represents for anyone concerned about their cardiovascular wellbeing.
7. Dairy Queen ½ lb Triple Signature Flamethrower Stackburger

Dairy Queen may be known for ice cream, but their Flamethrower Stackburger brings the heat in all the wrong ways. With 930 calories, 63g fat, and 24g saturated fat, this spicy triple-decker delivers a day’s worth of fat in one sitting.
The combination of three beef patties, pepper jack cheese, and Flamethrower sauce creates a perfect storm of unhealthy ingredients. The 2,020mg sodium content – nearly an entire day’s worth – can lead to water retention and blood pressure spikes.
Most concerning is how this burger’s spicy flavor profile might mask its nutritional dangers, making customers more likely to ignore the health implications while focusing on the taste experience.
8. Wendy’s Big Bacon Classic Triple

Recently named the fourth unhealthiest fast-food item globally, Wendy’s triple-patty monster doesn’t hold back on excess. The burger boasts an alarming 86g of total fat and 36g of saturated fat – amounts that would make any cardiologist cringe.
Three square beef patties combined with multiple bacon strips create a protein overload that far exceeds nutritional recommendations. The cheese and mayonnaise add significant fat without providing meaningful nutritional benefits.
What’s particularly troubling is Wendy’s marketing of this as a “classic” menu item, normalizing consumption of a burger that contains nearly two days’ worth of saturated fat in a single meal.
9. Red Robin Gold Medal Burger

The absolute worst offender on our list earns its gold medal for all the wrong reasons. This nutritional disaster packs a shocking 1,770 calories, 126g fat, and 51g saturated fat – more than double the recommended daily limit!
The burger features a beef patty topped with a literal mountain of bacon strips, two types of cheese, and a fried egg. The sodium content hits 3,820mg – more than 150% of the recommended daily maximum – putting enormous strain on your cardiovascular system.
Perhaps most alarming is how this burger is celebrated and promoted as a signature menu item rather than the occasional indulgence it should be considered.
10. Chili’s Bacon Rancher Burger

Rounding out our list is a sit-down restaurant offering that rivals any fast-food nightmare. Chili’s Bacon Rancher Burger delivers 1,690 calories, 123g fat, and 49g saturated fat – a day’s worth of calories and nearly 2.5 days of saturated fat in one meal!
The combination of multiple beef patties, bacon, ranch dressing, and two types of cheese creates a perfect storm of unhealthy ingredients. The 2,720mg sodium content can cause immediate water retention and discomfort for many diners.
What makes this burger particularly deceptive is the casual dining environment, which might lead customers to perceive it as healthier than fast-food alternatives when the nutritional reality suggests otherwise.
