In N Out Protein Style Burger | Menu Prices,

If you’re cutting carbs, going keto, or just looking for a lighter option at your favorite fast-food chain, you’ve probably heard about the protein style burger. But what exactly is it?

In-N-Out Protein Style simply means your burger is wrapped in lettuce instead of a traditional bun. It’s part of the not-so-secret customization options that health-conscious diners and low-carb eaters love. Whether you’re managing your macros or avoiding gluten, this bunless option keeps all the flavor without the extra carbs.

How to Order Protein Style at In-N-Out

Ordering Protein Style at In-N-Out is straightforward — but knowing a few insider tips can make it even easier.

Here’s how to do it:

Ordering Method	How to Order
In-Store or Drive-Thru	Simply say, “I’ll have a Double-Double, Protein Style,” or specify your custom order
Online Orders	Choose “lettuce wrap” or “Protein Style” under customization options (if available)
Secret Tip	Mix styles—like Animal Style or add grilled onions—for a personalized creation

You can even request no spread (to reduce carbs more) or extra lettuce and tomato for added crunch.

Tips for Eating In-N-Out Protein Style Like a Pro

Ordering Protein Style is easy—but eating it can be a little different from your typical burger experience. Since there’s no bun to soak up the juices, things can get a little messy. Here are some practical tips and insider advice to help you enjoy your meal without the mess:

1. Grab Extra Napkins

Protein Style burgers are wrapped in large, crisp lettuce leaves, which are refreshing—but not absorbent. You’ll want to grab a few extra napkins to stay tidy, especially if you’re on the go or eating in the car.

2. Eat It From the Pouch

In-N-Out serves Protein Style burgers in a paper burger pouch. Don’t toss it! Eating directly from the pouch helps catch drips, sauces, and loose toppings so they don’t end up in your lap. Think of it as your secret weapon for a cleaner eating experience.

How to Customize a Protein Style Burger

One of the best things about Protein Style is that it doesn’t limit your customization options—you’re simply swapping the bun for lettuce. Everything else is still fair game!

Here’s how you can build your perfect Protein Style burger:

Customization Tip	Description
Add Onions	Choose raw, grilled, or go Animal Style for mustard-grilled patties with grilled onions
Extra Veggies	Request more tomato, lettuce, or pickles for added freshness and crunch
Control the Spread	Ask for extra spread, no spread, or substitute with ketchup and mustard based on your taste
Combine Customizations	Mix styles—e.g., Animal Style + Protein Style for a lettuce-wrapped burger with bold flavors

Pro Tip:

If you’re sharing with a child or want a cleaner experience, don’t forget to ask for your burger to be cut in half. It makes a big difference in ease of eating—especially when Protein Style is involved!

Protein Style at In-N-Out: What It Is & Which Burgers You Can Customize

In-N-Out’s Protein Style option is one of the most popular “secret menu” customizations—and for good reason. When you ask for your burger Protein Style, the traditional bun is replaced with large, crisp lettuce leaves, creating a handheld wrap that’s fresh, low-carb, gluten-free, and keto-friendly.

But here’s the key detail: you can order any In-N-Out burger Protein Style—not just the Double-Double.

Burgers You Can Order Protein Style

Menu Item	Description
Hamburger Protein Style	Single beef patty wrapped in lettuce; customizable with or without spread, onions, tomato, pickles
Cheeseburger Protein Style	One beef patty with one slice of American cheese, wrapped in lettuce instead of a bun
Double-Double Protein Style	Two patties and two slices of cheese, customizable and lettuce-wrapped for a low-carb option

This option is completely customizable—you can remove spread, add grilled onions, skip cheese, or go full “Animal Style” while still keeping it Protein Style.

Why Choose Protein Style?

In-N-Out’s Protein Style burger isn’t just a trendy customization—it’s a practical solution for many dietary needs and lifestyle choices. Whether you’re cutting carbs, avoiding gluten, or just looking for a lighter meal, Protein Style has become a go-to choice for thousands of customers. Here’s why:

1. Low-Carb & Keto-Friendly Option

Protein Style is extremely popular among people following low-carb or ketogenic diets. By replacing the bun with fresh lettuce, you can cut out up to 30+ grams of carbs in a single order.

• For example: A regular Double-Double has 39g of carbs, while the Protein Style version has just 11g.
• It allows keto dieters to enjoy a fast-food burger without breaking ketosis.

2. Gluten-Free Friendly

Since Protein Style burgers use lettuce instead of bread, they are naturally free of gluten-containing ingredients. This makes them a smart choice for individuals with Celiac disease or gluten sensitivity.
Important Note: In-N-Out kitchens are not certified gluten-free facilities. While the ingredients are gluten-free, there’s a chance of cross-contact during preparation. Customers with severe gluten intolerance should use caution.

3. A Lighter, Fresher Alternative

Not everyone choosing Protein Style is on a specific diet—many just prefer a lighter, cleaner meal. Without the bun, the burger feels fresher and more vegetable-forward. It’s ideal for:

1. People watching their calorie intake
2. Customers who find traditional fast food too heavy
3. Those who want something more refreshing on a hot day

Protein Style offers flexibility and fits a range of dietary needs without compromising on flavor. Whether you’re going keto, gluten-free, or just want something lighter, it’s one of the easiest and healthiest hacks at In-N-Out.

Is In-N-Out Protein Style Keto & Low-Carb Friendly?

Absolutely. The Protein Style burger has become a cult favorite for keto dieters and low-carb lovers because it eliminates the carb-heavy bun.

Why it works for keto:

Keto-Friendly Feature	Description
High in Fat and Protein	Beef patty and cheese align well with keto macro requirements
Low Net Carbs	Replacing the bun with lettuce dramatically lowers carbohydrate content
Customizable	Easily adjust fat/protein ratios by removing spread or adding extra meat

In short, if you’re doing keto, In-N-Out Protein Style is one of the best fast food options you’ll find.
