3 min read

According to a June 2025 analysis by PlushCare, the fast-food chain with the unhealthiest fries is Five Guys. This article delves into why certain fast food fries are considered unhealthier than others, examining key nutritional metrics like calories, saturated fat, and sodium across several popular restaurants.

Quick Summary

A review of nutritional data reveals Five Guys serves the unhealthiest fries due to exceptionally high calorie, fat, and sodium counts in a single serving. Other contenders like Steak 'n Shake also have concerning nutritional profiles. We provide a detailed comparison to help you make informed choices.

Key Points

  • Five Guys Leads the Pack: Five Guys consistently ranks as having the unhealthiest fries due to high calorie, fat, and sodium counts, largely driven by large portion sizes.

  • Serving Size Matters: The generous serving sizes at Five Guys inflate the total nutritional values, making a single order far less healthy than a standard side from competitors.

  • Sodium and Saturated Fat are High: Excessive sodium and saturated fat levels in many fast-food fries contribute significantly to the risk of high blood pressure and heart disease.

  • Consider Healthier Alternatives: For healthier options, chains like Wendy's and In-N-Out offer fries with considerably lower calorie and sodium content.

  • Choose Moderation and Portion Control: To enjoy fries responsibly, opt for smaller portions, share with others, or limit the frequency of your consumption.

Nutritional Nightmare: Five Guys' Fries Crowned Unhealthiest

Several recent studies and nutritional analyses consistently point to one fast-food chain as the primary culprit for the unhealthiest fries: Five Guys. While the delicious taste and generous portion sizes are undeniable, the nutritional costs are staggering. A single, standard-size serving of Five Guys' fries can contain upwards of 953 calories, 57 grams of fat, and 1,327 milligrams of sodium, depending on the size and preparation. This is a significant portion of an average person's daily recommended intake in one side dish alone.

The sheer size of the Five Guys' servings is a major factor. Unlike other chains that offer a small, medium, and large, Five Guys' "regular" is far larger than a standard large at most competitors. This means that even if the per-gram nutrition isn't the absolute worst, the total volume makes it a nutritional outlier. For example, a large order of McDonald's fries contains a fraction of the calories found in a single Five Guys order.

The Competition: How Other Chains Stack Up

While Five Guys holds the top spot, other chains also offer fries with concerning nutritional values. Steak 'n Shake, Bojangles, and Smashburger are often cited in studies for having high saturated fat and sodium content. The cooking methods and ingredients, such as the type of oil used and the amount of salt added, play a crucial role in these nutritional differences.

A Comparative Look at Fast Food Fries

To illustrate the nutritional disparities, here is a comparison table of a standard-sized order of fries from several popular chains based on recent nutritional data:

Restaurant Serving Size (g) Calories Total Fat (g) Saturated Fat (g) Sodium (mg)
Five Guys ~411 ~953 ~57 N/A ~1327
Steak 'n Shake N/A N/A N/A N/A N/A
KFC N/A N/A N/A N/A ~1100
McDonald's ~117 (medium) ~320 ~15 ~1.5 ~189
Wendy's N/A ~239 N/A ~0.8 ~155
In-N-Out N/A ~360 ~15 ~1.5 ~150

Note: Nutritional information can vary based on region, portion size, and specific preparation. Some data points were not readily available for consistent serving sizes across all chains.

The Impact of High Sodium and Saturated Fat

The health implications of consuming high levels of sodium and saturated fat are well-documented. Excessive sodium intake is linked to high blood pressure, heart disease, and stroke. A single order of fries from Five Guys can provide more than half of the recommended daily sodium intake. Similarly, high levels of saturated fat can raise cholesterol levels, contributing to heart disease.

Understanding Calorie Density

Beyond portion size, the cooking process itself contributes to calorie density. Fast food fries are typically double-fried, first at a lower temperature to cook the potato and then at a higher temperature to crisp the exterior. This process, coupled with the generous use of oil, increases the calorie and fat content significantly compared to homemade or air-fried versions. The type of oil also matters; many fast-food chains use vegetable oils high in saturated fats.

How to Make Healthier Fry Choices

If you can't resist a side of fries, here are a few ways to make a more mindful choice:

  • Choose smaller portions: A small order is always a better option than a large. Sharing with a friend is another strategy to reduce your intake.
  • Opt for healthier chains: As the comparison table shows, some chains like Wendy's and In-N-Out offer significantly lower calorie, fat, and sodium counts in their standard fries.
  • Limit your frequency: Treat fast-food fries as an occasional treat rather than a regular side dish.
  • Ask for no salt: Requesting fries with no salt forces a fresh batch and allows you to control the sodium yourself.
  • Consider alternatives: Many fast-food menus now include healthier sides like salads, applesauce, or baked potatoes. Choosing these options can dramatically improve the nutritional profile of your meal.

Conclusion: The Unhealthy Reality of Some Fast-Food Fries

When it comes to the question of which fast food restaurant has the unhealthiest fries, the answer is clear: Five Guys. The combination of oversized portions and high levels of fat, sodium, and calories puts it at the top of the list. While the taste may be appealing, the nutritional consequences are significant. By being aware of these nutritional facts and making more conscious choices, consumers can still enjoy fast food in moderation without overindulging in its unhealthiest offerings.
