What Fast Food is Worse Than McDonald's? A Nutritional Breakdown

4 min read

According to a 2025 World Atlas report, Wendy's was ranked as the unhealthiest fast food chain, while McDonald's landed at number seven on the same list. While McDonald's is frequently cited as a poster child for unhealthy eating, several other chains offer menu items that are significantly worse for you in terms of calorie count, sodium, and saturated fat, proving that the question 'what fast food is worse than McDonald's?' has many answers.

Quick Summary

Several fast food chains, including Wendy's, Sonic, and Five Guys, are often worse than McDonald's on nutritional metrics. Specific combo meals at these restaurants can contain more calories, saturated fat, and sodium than comparable McDonald's options, challenging the common perception of fast food health.

Key Points

  • Wendy's and Sonic often rank as unhealthier chains: Studies in 2025 identified Wendy's and Sonic among the top unhealthiest chains due to high-calorie, high-sodium combo meals like the Triple Baconator and large cheeseburger combos.

  • Five Guys excels in unhealthy burgers: A 2024 study named Five Guys as having the unhealthiest cheeseburger and fries, containing significantly more saturated fat than other popular chains.

  • Single McDonald's meals often have lower nutritional negatives: Compared to many of its competitors' mega-meals, a standard McDonald's combo often contains fewer calories, less saturated fat, and less sodium.

  • Individual menu items vary greatly: The overall unhealthiness depends on the specific meal chosen. Even chains with a healthier reputation can have highly caloric and fatty items, while a chain like McDonald's offers some relatively lower-impact choices.

  • Smarter choices can be made anywhere: Opting for grilled options, controlling portion sizes, and avoiding sugary drinks are effective strategies for reducing the negative health impact of fast food, regardless of the chain.

  • Fat, sodium, and sugar are the key culprits: When evaluating fast food, pay close attention to the content of saturated fat, sodium, calories, and added sugar, which are the main drivers of unhealthiness in most fast food meals.

The Nutritional Metrics That Matter

To determine what fast food is worse than McDonald's, it's crucial to look beyond reputation and focus on specific nutritional indicators. The key culprits in fast food are high levels of calories, saturated fat, sodium, and sugar. A single meal that contains excessive amounts of these nutrients can easily push you over your daily recommended limits, increasing the risk of health issues like heart disease and type 2 diabetes. For instance, the American Heart Association recommends no more than 2,300 mg of sodium per day for most adults, a number that many fast food combo meals can exceed on their own.

Chains with Worse Menu Items Than McDonald's

Numerous studies and reports consistently rank several fast-food competitors above McDonald's for overall unhealthiness, largely due to particularly egregious menu items and large portion sizes.

Wendy's

Often topping lists for the unhealthiest chain, Wendy's earns this reputation with mega-meals like the Triple Baconator combo, which includes a large fries and medium Frosty. This single meal can reach over 2,100 calories, far exceeding the caloric intake of most standard McDonald's combos. The saturated fat and sodium levels in such a meal are also alarmingly high.

Sonic Drive-In

Sonic's menu, known for large portions and sugary beverages, is another major offender. A Sonic cheeseburger combo with medium tots and a large Cherry Limeade can exceed 1,600 calories and provide over 3,000 milligrams of sodium, a dangerous level for a single meal. The combination of fried foods and high-sugar drinks is a fast track to exceeding daily nutritional limits.

Five Guys

For burger enthusiasts, Five Guys often ranks as the chain with the most unhealthy burger. A 2024 PlushCare study used a points system based on calories, sugar, saturated fat, and sodium, finding the Five Guys cheeseburger to have the highest score, with 73% more saturated fat than any other burger in the study. The chain also consistently ranks poorly for its least healthy fries.

KFC

While fried chicken is notoriously high in fat, KFC's menu can also outpace McDonald's in unhealthiness, particularly with its large combo meals. A three-piece Extra Crispy combo with sides like a biscuit and gravy can hit 1,300 calories, over 2,900 mg of sodium, and 22 grams of saturated fat, before even adding a soda.

Taco Bell

Comparisons between Taco Bell and McDonald's show mixed results, but simulations have indicated that, in general, McDonald's meals often have higher calories from fat, cholesterol, and sodium compared to Taco Bell's offerings. However, specific loaded burritos or combo deals at Taco Bell can still be exceptionally high in calories and sodium.

A Comparative Look: Menu Item vs. Menu Item

It's important to compare specific menu items rather than just overall brand reputation. Here is a comparison of typical combo meals from McDonald's and two other chains often cited as unhealthier.

Item Calories Saturated Fat (g) Sodium (mg)
McDonald's Big Mac Meal (Big Mac, medium fries, medium coke) ~980 ~14 ~1,300-1,500
Wendy's Triple Baconator Meal (Triple Baconator, large fries, med frosty) ~2,160 ~54 ~3,400
Sonic Cheeseburger Combo (Cheeseburger, medium tots, large Cherry Limeade) >1,600 (High) >3,000

This table illustrates how a single meal choice can make a significant difference. The Triple Baconator combo from Wendy's, for example, packs more than double the calories and triple the saturated fat and sodium of a Big Mac meal.

Making Smarter Fast Food Choices

While it’s clear that many fast food options are nutritionally worse than McDonald’s, the key to healthier eating lies in moderation and smarter choices, regardless of the restaurant.

  • Prioritize Grilled Options: Opt for grilled chicken sandwiches instead of fried versions. Many chains, including McDonald's and Chick-fil-A, offer this alternative, which significantly reduces saturated fat and calorie content.
  • Modify Your Order: Don't be afraid to ask for modifications. Hold the cheese, bacon, or high-calorie sauces. Get dressings on the side for salads.
  • Downsize Your Meal: Instead of a large combo, choose a smaller burger and a side salad or apple slices instead of fries. Skip the sugary soda and opt for water.
  • Control Portion Sizes: If you are determined to have a burger and fries, stick to a single patty and the smallest portion of fries available.
  • Research Before You Go: Most fast-food chains publish their full nutritional information online. Checking this before you order can prevent a surprise nutritional bomb.

Conclusion

For those asking, what fast food is worse than McDonald's?, the answer is clear: several major chains, including Wendy's, Sonic, and Five Guys, have menu options that surpass McDonald's in negative nutritional impact. While the Golden Arches may carry a heavy reputation, competitors' super-sized combo meals and indulgent burgers often feature much higher calorie, saturated fat, and sodium counts. By understanding the specific nutritional pitfalls of each chain and making more informed, conscious decisions, you can navigate the fast-food landscape more healthily. It's not just about avoiding McDonald's, but about being a mindful consumer wherever you choose to eat fast food.
