Introduction
If you’ve ever been to In-N-Out, you know their menu isn’t the full story. Sure, the classic burgers are great, but the real magic happens when you start exploring customizations. And two of the most famous ones? Protein Style and Animal Style.
I’ve eaten both more times than I’d like to admit, and let me tell you—choosing between them isn’t easy. One is healthier and fresh, the other is rich and loaded with flavor. But which one deserves a spot in your order? Let's break it down.
What is Protein Style?
The Bun-Less, Lettuce-Wrapped Alternative
Protein Style is In-N-Out’s answer to anyone who wants a burger without the bun. Instead, the juicy beef patty, cheese, tomato, onions, and spread are all wrapped in a crisp lettuce leaf.
It’s a lighter, fresher take on the classic burger. Plus, if you’re skipping carbs, it’s a solid choice. I remember the first time I tried it—I was skeptical, but that crunchy lettuce and juicy patty combo actually worked.
Why People Love It
- ✔ Low-carb & keto-friendly – No bun = fewer carbs.
- ✔ Refreshing & crisp – The lettuce adds a crunch you don’t get with bread.
- ✔ Less heavy – You can enjoy the burger without feeling too full.
Downsides of Protein Style
- ❌ Messy – The lettuce can’t hold everything as well as a bun.
- ❌ Less flavor impact – Without the bun, you miss out on that extra texture.
- ❌ Not for bread lovers – If you love a good bun, this might not hit the spot.
What is Animal Style?
The Ultimate Flavor Boost
If Protein Style is the healthy choice, Animal Style is the opposite—in the best way possible. It takes a regular burger and loads it up with:
- Mustard-grilled patties (giving them a tangy, crispy edge)
- Extra spread (their signature sauce, like Thousand Island but better)
- Grilled onions (caramelized to perfection)
- Pickles (not in the regular burger, but a must for this one)
Why People Love It
- ✔ More flavor – The mustard-grilled patty and spread add extra richness.
- ✔ Juicier – The added toppings make every bite saucier and more satisfying.
- ✔ A fan-favorite – It’s one of the most famous In-N-Out hacks for a reason.
Downsides of Animal Style
- ❌ Messy – The extra sauce and grilled onions drip everywhere.
- ❌ Higher in calories – With more sauce and grilled toppings, it’s not exactly a “light” option.
- ❌ Can be too rich – If you prefer a simpler burger, this might feel like too much.

Which One is Better?
This depends on what you’re looking for.

- Personally? If I’m feeling indulgent, I go for Animal Style. If I want to eat lighter, I pick Protein Style. And sometimes, I combine both—yes, you can order Protein Style + Animal Style and get the best of both worlds.
Final Thoughts
