Frequently Asked Questions (FAQ)

How does a Double-Double compare to a Big Mac?

An In-N-Out Double-Double has about 670 calories with 41 grams of protein, while a McDonald's Big Mac has 563 calories with 26 grams of protein. The Double-Double is higher in calories but delivers significantly more protein due to its two full-sized beef patties compared to the Big Mac's thinner patties. The Double-Double also uses fresher ingredients with no freezing or artificial additives, which appeals to health-conscious consumers.

How many calories does Protein Style save?

Ordering a Double-Double Protein Style instead of the standard version saves approximately 150 calories, bringing it from 670 down to about 520 calories. The lettuce wrap replaces the bun, reducing carbohydrates from 39 grams to just 11 grams. This modification is one of the most effective calorie-cutting strategies at In-N-Out and is especially popular among those following low-carb or keto diets.

What does Animal Style add to the calorie count?

Animal Style adds roughly 100 extra calories to any burger, bringing a Double-Double from 670 to about 770 calories. The additions include extra spread, grilled mustard-cooked patties, and extra pickles, with the extra spread being the primary calorie contributor. The Animal Style modification also increases sodium and fat content, so it is best reserved for occasional indulgences rather than everyday orders.

What are the healthiest secret menu options at In-N-Out?

The "Protein Style" lettuce wrap is the most popular lighter option, saving about 150 calories and most of the carbohydrates from the bun. You can also order a "Flying Dutchman," which is just two patties and two slices of cheese with no bun or toppings, coming in at roughly 330 calories. Another strategy is ordering a single hamburger without spread, which comes in under 310 calories while still delivering a satisfying fresh-grilled burger.

How does In-N-Out compare to Five Guys on calories?

An In-N-Out Double-Double has about 670 calories, while a Five Guys regular Cheeseburger (which also has two patties) comes in at approximately 840 calories. Five Guys burgers are larger with more generous toppings and a bigger bun, which accounts for the roughly 170-calorie difference. In-N-Out generally offers a lighter fast food burger experience, though Five Guys allows more topping customization at no extra charge.
