  • Based on the nutrition facts published for their online menu, the best macros estimate for one serving of the dressing is: 40 calories, 4g net carbs, and 1g protein. 

What You Should Not Order

On a low-carb diet, buns, fries, and shakes must be avoided. You should also skip the ketchup, as you may be adding about 4g net carbs to your meal every time you add ketchup to your protein style In-N-Out burger. To further reduce the net carbs, you can also do away with the tomatoes and go light on the dressing.
