In-N-Out Burger vs Five Guys: Which Is Actually Healthier?

It’s the heavyweight burger brawl that pits West Coast simplicity against East Coast abundance. In one corner, we have In-N-Out Burger, the California-based icon with a famously minimalist menu, a cult-like following, and a reputation for fresh, no-fuss quality. In the other corner stands Five Guys, the Virginia-born powerhouse known for its customizable burgers, generous portions, and mountains of fresh-cut fries.

Both chains pride themselves on using fresh, never-frozen beef and potatoes cut in-store. But when the wrappers are off and the nutrition facts are on the table, which burger joint actually serves up a healthier meal? We fired up the Snackly app, ran the numbers, and analyzed the Coach Scores to bring you the definitive, data-driven verdict.

The Matchup

In-N-Out and Five Guys are often compared because they occupy a similar space in the fast-food world: a step up from the drive-thru giants, focusing on a simple core menu of burgers and fries done well. You choose In-N-Out for its streamlined efficiency, classic flavors, and budget-friendly prices. You head to Five Guys when you want endless customization, a heartier, more substantial meal, and don't mind paying a premium for it. But beneath the surface-level similarities lies a stark nutritional divide.

Tale of the Tape

To get a bird's-eye view of how these chains stack up, we analyzed the Coach Score of every core menu item provided. The Coach Score (from 0-100) is Snackly’s proprietary rating that assesses the nutritional quality of a food item, taking into account calories, macronutrients (protein, carbs, fat), fiber, and more. A higher score indicates a better nutritional profile.

* In-N-Out Burger:

* Average Coach Score: 49.8 / 100

* Number of Items Analyzed: 11

* Category: The Lightweight Contender

* Five Guys:

* Average Coach Score: 53.7 / 100

* Number of Items Analyzed: 11

* Category: The Heavy-Hitting Brawler

Right away, the data reveals a surprising trend. Despite its reputation for larger-than-life portions, Five Guys actually has a higher average Coach Score. This tells us that, on average, their menu items offer a better balance of nutrients for their caloric density—largely driven by significantly higher protein content in their burgers. In-N-Out's menu, while lower in calories overall, has several items like shakes and specialty fries that pull down its average score. This initial data point suggests that if you choose wisely, Five Guys might offer a more nutritionally robust meal, while In-N-Out’s strength lies in its lower-calorie baseline.

Best Overall Order at Each

A chain is only as good as its best player. We looked for the single highest-scoring item on each menu to see who brings the most nutritional value to the table.

In-N-Out Winner: French Fries

* Nutrition: 395 calories, 7g protein, 54g carbs, 18g fat, 2g fiber

* Coach Score: 54/100

It might be shocking that a side of fries takes the top spot, but In-N-Out’s fries are a relatively modest, low-calorie option. With a Coach Score of 54, they outperform every burger on the menu, thanks to their simple preparation and reasonable portion size. They provide a decent energy boost from carbs without the excessive fat and calories found in other items.

Five Guys Winner: Little Hamburger

* Nutrition: 540 calories, 27g protein, 39g carbs, 30g fat, 2g fiber

* Coach Score: 59/100

The Little Hamburger from Five Guys is a nutritional powerhouse. While it has more calories than most of In-N-Out's burgers, its Coach Score of 59 is the highest of any item in this entire matchup. This is due to its impressive 27 grams of high-quality protein, which provides excellent satiety and helps balance the meal’s macros, making it a more substantial and nutritionally balanced choice.

Round Winner: Five Guys

With a significantly higher Coach Score, the Five Guys Little Hamburger wins this round. It delivers a far more satisfying and protein-packed meal, making its calorie count work harder for you.

Protein Showdown

For those looking to build muscle or simply stay full longer, protein is the name of the game. We pitted the best high-protein pick from each chain against each other.

In-N-Out's Contender: 3x3 (Triple Meat, Triple Cheese)

* Nutrition: 860 calories, 53g protein, 39g carbs, 56g fat

* Coach Score: 48/100

The 3x3 is an off-menu beast that packs a serious protein punch. With 53 grams of protein, it’s guaranteed to crush hunger. However, this comes at the cost of 860 calories and a hefty 56 grams of fat, landing it a middling Coach Score of 48.

Five Guys' Contender: Cheeseburger

* Nutrition: 980 calories, 55g protein, 40g carbs, 65g fat

* Coach Score: 57/100

The standard Five Guys Cheeseburger is a two-patty behemoth that delivers an incredible 55 grams of protein. Yes, the calories (980) and fat (65g) are staggering, but its Coach Score of 57 is remarkably high. The score reflects an excellent protein-to-carb ratio and recognizes the sheer muscle-building potential of this burger.

Round Winner: Five Guys

While both are calorie bombs, the Five Guys Cheeseburger takes the crown. It delivers more protein and earns a much higher Coach Score, indicating a better nutritional composition for its size. If maximizing protein is your absolute priority and calories are no object, Five Guys is the undisputed champion.

Best for Weight Loss / GLP-1

For those managing their weight, following a GLP-1 lifestyle, or simply seeking a lighter meal, calorie control and satiety are key. Here, the story flips completely.

In-N-Out's Ace: Protein Style Burger

* Nutrition: 240 calories, 13g protein, 11g carbs, 17g fat, 3g fiber

* Coach Score: 53/100

This is where In-N-Out truly shines. By swapping the bun for a crisp lettuce wrap, the Protein Style Burger becomes one of the best fast-food options anywhere for calorie-conscious eaters. At just 240 calories, it provides a satisfying 13 grams of protein and minimal carbs, making it an ideal choice for a light lunch that won't derail your diet.

Five Guys' Best Effort: Little Hamburger

* Nutrition: 540 calories, 27g protein, 39g carbs, 30g fat

* Coach Score: 59/100

Five Guys doesn’t really play in the "light" category. Their lowest-calorie burger, the Little Hamburger, clocks in at 540 calories—more than double the In-N-Out option. While its protein content is excellent, the calorie load is simply too high to compete in a weight-loss context.

Round Winner: In-N-Out

This isn't even a contest. In-N-Out wins by a landslide. The Protein Style Burger is a brilliant menu hack that gives health-conscious customers a genuinely delicious, low-calorie, and high-satiety option that Five Guys can't match.

Best for Low Carb / Keto

Following a low-carb or ketogenic diet can be tough at a burger joint. One chain makes it easy, while the other requires you to go off-road.

In-N-Out's Go-To: Protein Style Double-Double

* Nutrition: 520 calories, 33g protein, 11g carbs, 39g fat

* Coach Score: 46/100

With two patties and two slices of cheese wrapped in lettuce, the Protein Style Double-Double is a fantastic low-carb meal. It delivers a whopping 33 grams of protein and 39 grams of fat to keep you full and in ketosis, all while containing just 11 grams of carbohydrates.

Five Guys' Option: Burger Bowl (No Bun)

* Nutrition: (Estimated, as it's not an official menu item with data)

Five Guys will happily serve you any of their burgers in a bowl without the bun, which drastically cuts the carbs. However, this isn't an official item with standardized nutrition data provided. Based on their standard Hamburger (39g carbs), removing the bun would likely bring the carb count down to single digits, but you're left guessing the final numbers.

Round Winner: In-N-Out

In-N-Out wins for offering a clear, official, and nutritionally transparent low-carb option directly on their "Not-So-Secret Menu." You know exactly what you're getting, making it the reliable choice for any carb-counter.

Biggest Landmines

Every menu has its hidden traps—items that can sabotage your health goals with a single order.

In-N-Out's Trap: Animal Style Fries

* Nutrition: 750 calories, 18g protein, 58g carbs, 52g fat

* Coach Score: 45/100

They’re legendary, but they're also a nutritional disaster. Dousing the standard 395-calorie fries in cheese, spread, and grilled onions more than doubles the fat and nearly doubles the calories. With a dismal Coach Score of 45, this side dish has more calories than a Double-Double and should be considered a "once in a while" indulgence, at best.

Five Guys' Trap: The Bacon Cheeseburger & The Hot Dog

* Bacon Cheeseburger: 1060 calories, 58g protein, 40g carbs, 71g fat, Coach Score: 54/100

* Hot Dog: 545 calories, 18g protein, 40g carbs, 35g fat, Coach Score: 42/100

The Bacon Cheeseburger is an absolute calorie monster, packing half a day's worth of calories and more than a full day's recommended saturated fat for many adults. But the most nutritionally poor item on the entire Five Guys menu is the humble Hot Dog. With the lowest Coach Score of the matchup at 42, it’s surprisingly high in calories and fat for its relatively low protein content.

Round Winner: Five Guys

Five Guys takes the loss here, "winning" the award for the bigger landmines. The potential for a single item to exceed 1,000 calories makes it a much riskier menu to navigate if you're not paying close attention.

The Final Verdict

So, which chain is actually healthier? The data points to a nuanced conclusion: it entirely depends on your health goals.

Five Guys wins on nutritional quality and protein, boasting a higher average Coach Score and offering burgers that are densely packed with protein. If you're an athlete looking to refuel, or your main goal is hitting a high protein target without worrying about calories, Five Guys is the superior choice.

However, In-N-Out is the decisive winner for anyone managing their weight, counting calories, or living a low-carb lifestyle. Its menu is fundamentally lower in calories, and the availability of the "Protein Style" option gives it a level of dietary flexibility that Five Guys can't touch. In-N-Out empowers the health-conscious consumer with control and clear, lighter choices.

For that reason, we give the overall "healthier" title to In-N-Out Burger. It makes staying on track easy, accessible, and affordable, proving that you don’t have to sacrifice flavor for a mindful meal.
