A standard Protein Style hamburger at In-N-Out lists 210 calories, while a Protein Style cheeseburger lists 280 calories.
If you order a “protein burger” at In-N-Out, you’re almost always talking about Protein Style: the bun gets swapped for a lettuce wrap. That single swap changes the calorie picture fast, but the rest of the order still decides how the meal lands.
This page gives you the official numbers, then shows a plain way to adjust them when you change patties, cheese, or sauces. You’ll finish with a repeatable method you can use at the counter.
What “Protein Burger” Means At In-N-Out
In-N-Out doesn’t sell a separate item called “protein burger” on the printed menu. People use the phrase to mean a burger ordered Protein Style, where lettuce replaces the bun.
That swap trims most of the burger’s carbs and drops a chunk of calories, but it doesn’t turn the meal into a free pass. Beef, cheese, and spread still carry most of the energy.
Calories In Protein Burger In-N-Out: What The Numbers Show
In-N-Out publishes nutrition facts for its core burgers, including the Protein Style versions. The PDF is dated January 2026 and lists calories, macros, and sodium for each item. You can view it on the In-N-Out nutrition information page and in the downloadable In-N-Out Burger® Nutrition Facts PDF.
Here are the headline calorie counts from that sheet: Protein Style hamburger is 210 calories, Protein Style cheeseburger is 280 calories, and Protein Style Double-Double is 460 calories. Protein listed on the same lines is 12 g, 16 g, and 30 g, in that order.
Why the lettuce wrap changes the count
The bun is a steady source of calories and carbs. When it leaves the sandwich, the lettuce and extra tomato/lettuce weight don’t add much energy, so the total drops.
If you want context for how low lettuce runs, standard nutrition databases list iceberg lettuce at single-digit calories per cup. You can cross-check typical lettuce entries in USDA FoodData Central when you’re estimating swaps at home.
What stays the same when you order Protein Style
The beef patty doesn’t change. If you order a cheeseburger or Double-Double, the cheese stays in. The spread is still spread.
So the calorie count still tracks with patties, cheese, and sauces, not with the bun swap alone.
Calories In In-N-Out Protein Style Burger With Common Choices
People rarely order a burger in a vacuum. Onions, mustard, ketchup, and the default spread can shift calories, sodium, and carbs in ways you can feel after the meal.
In-N-Out’s sheet lists “with mustard & ketchup instead of spread” for the bun burgers, which helps you see how the sauce choice moves the number. The Protein Style lines in the PDF are the clearest baseline for a lettuce-wrapped order.
How To Estimate Your Calories When You Customize
Custom orders are the norm at In-N-Out. The cleanest way to estimate is to start with a published baseline, then add or subtract using the gaps between items that differ by one thing.
This works because the menu is built from a small set of parts: bun or lettuce, one or two patties, zero to two cheese slices, and the same core toppings.
Step 1: Pick the closest official baseline
If you’re ordering a lettuce wrap, start with the Protein Style version that matches your patty count and cheese count. That’s the number you can trust most.
If you’re ordering a bun burger with sauce swaps, the “mustard & ketchup instead of spread” lines show the impact of skipping spread on a standard build.
Step 2: Use differences between items as your add-ons
Want to estimate what one cheese slice adds? Compare the Protein Style cheeseburger (280) to the Protein Style hamburger (210). That’s a 70-calorie gap.
Want to estimate the second patty plus the second cheese slice? Compare the Protein Style Double-Double (460) to the Protein Style cheeseburger (280). That’s a 180-calorie gap.
Step 3: Treat fries and drinks as their own line items
It’s easy to obsess over the burger and forget the sides. In the same PDF, French fries list 360 calories. Many fountain drinks land in the 100–500+ range by size, while unsweetened iced tea lists 0 calories.
Build the meal total by stacking the burger, the side, and the drink. That’s the number your body sees.
Protein Style Burger Nutrition At A Glance
The table below keeps it simple: item name, calories, and protein grams. This lets you compare the lettuce-wrapped options to the bun versions without scanning the whole PDF.
| Menu item | Calories | Protein (g) |
|---|---|---|
| Hamburger w/ onion | 360 | 16 |
| Hamburger, mustard & ketchup instead of spread | 300 | 16 |
| Hamburger Protein Style (lettuce wrap) | 210 | 12 |
| Cheeseburger w/ onion | 430 | 20 |
| Cheeseburger Protein Style (lettuce wrap) | 280 | 16 |
| Double-Double w/ onion | 610 | 34 |
| Double-Double Protein Style (lettuce wrap) | 460 | 30 |
| French Fries | 360 | 6 |
Calorie Deltas You Can Reuse At The Order Window
The table below turns those “difference” checks into a small cheat sheet. It won’t cover every secret-menu twist, but it handles the swaps most people make in real life.
| Change | Calorie change | How it’s derived |
|---|---|---|
| Swap bun burger → Protein Style (1 patty, no cheese) | -150 | Hamburger w/ onion 360 → Protein Style hamburger 210 |
| Add 1 cheese slice to a Protein Style burger | +70 | Protein Style cheeseburger 280 − Protein Style hamburger 210 |
| Add 2nd patty + 2nd cheese slice (Protein Style) | +180 | Protein Style Double-Double 460 − Protein Style cheeseburger 280 |
| Skip spread on a bun hamburger | -60 | Hamburger w/ onion 360 → mustard & ketchup instead of spread 300 |
| Skip spread on a bun cheeseburger | -50 | Cheeseburger w/ onion 430 → mustard & ketchup instead of spread 380 |
| Add fries to any burger order | +360 | French Fries line item |
| Pick unsweetened iced tea instead of a small cola | -130 | Small cola 130 → unsweetened iced tea 0 |
Protein, Carbs, And Fat: What Those Numbers Suggest
Calories are the headline, yet macros tell you why two meals with the same calories can feel different. In-N-Out’s sheet lists total carbs and protein for each burger line right next to the calories.
A Protein Style hamburger lists 9 g of total carbs and 12 g of protein. The Protein Style Double-Double lists 12 g of total carbs and 30 g of protein. That’s a big swing in protein with a small swing in carbs.
When a lettuce-wrapped burger fits better than a bun burger
If you’re watching carbs, the lettuce wrap is the simple move. You still get the same core burger, just without most of the bun carbs.
If you’re tracking protein, the single-patty Protein Style hamburger may feel light. The Double-Double version brings more protein, yet it also brings more calories and saturated fat.
Sodium is the quiet number that stacks fast
Even without a bun, sodium can run high on cheese and Double-Double orders. The Protein Style Double-Double line lists 1,390 mg of sodium, which can matter if you’re balancing salt across the day.
If you want a baseline for daily values that show up on U.S. labels, the FDA guide to the Nutrition Facts label explains how percent daily value is set and how to read it.
Small Tweaks That Shift The Total
When people say they’re “just getting a burger,” the hidden calories often come from two spots: sauce and sides. The good news is you can change those without changing the core sandwich.
If you like the tang of mustard and ketchup, swapping away from spread can drop calories on the bun burgers listed in the PDF. That swap also cuts fat, which is where a lot of calorie density lives.
Cheese and patties are straight math
Cheese adds 70 calories when you compare the Protein Style cheeseburger to the Protein Style hamburger. A second patty plus a second cheese slice adds 180 calories when you compare the Protein Style Double-Double to the Protein Style cheeseburger.
If you’re building a plan for the week, those two deltas do most of the work.
Drinks are the easiest win
Sweet drinks climb fast as the cup gets bigger. If you want something cold without the sugar hit, unsweetened iced tea shows 0 calories on the sheet, and water stays water.
If you want a shake, treat it like dessert, since the listed shakes sit in the high-calorie range.
Order Combos That Keep Calories Predictable
These combos use only items with published numbers in the In-N-Out sheet, so you can total them without guesswork. Mix and match to fit your own targets.
Lower-calorie, lighter feel
- Protein Style hamburger (210) + unsweetened iced tea (0)
- Protein Style cheeseburger (280) + water (0)
- Protein Style hamburger (210) + small cola (130) when you want the drink
More protein, still bun-free
- Protein Style Double-Double (460) + unsweetened iced tea (0)
- Protein Style cheeseburger (280) + milk (160) when you want extra protein in the drink
Classic meal math that surprises people
A Protein Style burger can feel “light,” then fries bring the total right back up. A Protein Style hamburger (210) plus fries (360) lands at 570 calories, before any drink.
If you want the full picture for each drink size, the same PDF lists calories for cola, lemonade, tea, and shakes across cup sizes.
Allergens And Ingredients: What To Check Before You Order
Protein Style changes the bun, not the kitchen. If you avoid gluten, the lettuce wrap helps, yet cross-contact can still happen where buns and burgers share prep space.
In-N-Out flags this on its nutrition page and points readers to allergen details online. Use the nutrition and allergen notes before you order if you have food allergies or celiac disease.
Use This 30-Second Method Every Time
Start with the official Protein Style line that matches your order. Add cheese and patties using the deltas in the second table. Then tack on fries and your drink as separate items.
Do that once or twice and it becomes second nature. You’ll stop guessing, and you’ll know what you’re ordering before the tray hits the table.
