In-N-Out Protein Style Burger

Now that’s what a hamburger’s all about!

If you’ve ever visited the West Coast or traveled to Texas, you’ve probably seen long lines of cars wrapped around In-N-Out Burger restaurants. For those of you who are lucky enough to have one near you, we’ve got ya covered with our In-N-Out keto dining guide.

We’ve hacked the traditional In-N-Out menu and their Not-So-Secret Menu to help you keep it keto while enjoying their delicious fast food burgers on the go!

The basics of ordering In-N-Out keto style:

  • Avoid buns, bread, milkshakes, and French fries.
  • When in doubt, leave dipping sauces and condiments out.
  • For drinks, stick with water, unsweetened iced tea, Coke Zero, or Diet Coke products.

Please note that some condiments at In-N-Out may be considered dirty keto by some, so enjoy based on what works best for your low-carb lifestyle.

While we love to have exact macros for our keto dining guides, In-N-Out makes it a little tricky as their nutrition info for all of their burgers includes their special spread sauce, or ketchup and mustard. So it’s a little hard to get an accurate breakdown for ya. Just be sure to skip the bun, ketchup, and the spread as mentioned above and you’ll be keeping it keto with a super low carb lunch or dinner!

Here’s how to keep it keto-friendly when ordering at In-N-Out:

“I’ll have the Double Double Protein Style with no spread, add tomatoes, mustard, pickles, and onions.” 

The Double-Double is one of In-N-Out’s most popular burgers. Skip the spread and asked for it to be protein style (lettuce wrapped), and you’ll have a delicious juicy burger that will hit the spot. Like your onions grilled? Go ahead and order your Double Double with grilled onions for more flavor.

If you have some extra carbs you can spare for the day, then treat yourself to Animal Style – which is simply grilled onions combined with their special spread. According to MyFitness Pal, a packet of spread has 2g net carbs. I would suggest asking for a packet instead of ordering it already on the burger, that way you can control how much you have on your burger.

IN-N-OUT Flying Dutchman

“I’ll have the Flying Dutchman with tomatoes, mustard, pickles, and onions.”

In-N-Out’s burgers are pretty much the best ever, and trust me you won’t even miss the bun! What we like about the Dutchman is that it’s simply just two beef patties on the outside that act as the “bun”, with the cheese on the inside. Top with tomatoes, mustard pickles, and onions if you like, and you pretty much have the most perfect keto burger ever. YUMMO!

You really can’t go wrong with any burger at In-N-Out, but what we like about the Flying Dutchman is that it’s just two meat patties on the outside that act as the “bun”, with the cheese on the inside. Stetson added lettuce, tomato, and onion (no additional charge) so this burger – with all the same components as a Double-Double – costs quite a bit less than both the Quad Quad and 2 Double-Doubles. Now that’s what I call a budget-friendly keto meal deal!

2 Flying Dutchmen [4 patties]: $4.60
1 Quad Quad [4 patties]: $6.15
You save: $1.55

2 Flying Dutchmen [4 patties]: $4.60
2 Double Double [4 patties] : $7.70
You save: $3.10
