The Standard Double-Double's Protein Power

The Double-Double is a classic fast-food icon, especially for those familiar with the In-N-Out chain. It consists of two 100% beef patties, two slices of American cheese, lettuce, tomato, and spread, all served on a freshly baked bun. The primary source of protein in this burger comes from the two beef patties, with the cheese providing a supplementary amount. A single standard Double-Double offers 34 grams of protein, a significant portion of the recommended daily intake for most adults.

This high protein count is what makes the Double-Double a popular choice for those looking for a satiating meal. Protein is essential for building and repairing muscle tissue, producing enzymes and hormones, and contributing to feelings of fullness. For individuals with a goal of maintaining or increasing muscle mass, including a meal with this much protein can be beneficial. However, it is crucial to consider the entire nutritional profile, as this item also contains considerable amounts of fat and sodium.

Macronutrient Breakdown

Beyond just protein, it's important to understand the full picture of the Double-Double's nutrition. The standard version of this burger is not just a protein powerhouse; it's also high in fat and carbohydrates. Here is a typical breakdown based on official data:

Calories: 610 calories
Total Fat: 34g
Saturated Fat: 15g
Carbohydrates: 41g
Protein: 34g
Sodium: 1660mg

This nutritional information highlights the burger's role as a calorie-dense and rich meal. The bun and the spread contribute to the carbohydrate content, while the beef and cheese are the main drivers of the protein and fat.

Customizing for Your Protein Goals

For those who enjoy the flavor of a Double-Double but want to manage their overall nutrient intake more carefully, In-N-Out offers several customization options. The most famous is the 'Protein Style' modification, which significantly alters the macro profile without sacrificing much protein.

The 'Protein Style' Double-Double

Ordering a Double-Double 'Protein Style' means the bun is replaced with a crisp lettuce wrap. This simple change has a profound effect on the nutritional values:

Protein Content: The protein remains nearly identical at 33 grams.
Carbohydrate Reduction: The carb count drops dramatically from 41g to just 11g, making it a viable option for low-carb or ketogenic diets.
Calorie Reduction: The overall calorie count decreases to approximately 520, a drop of nearly 100 calories.

List of Common Modifications

Add a Patty: Adding a third patty will increase the protein even further, though it will also add more fat and calories.
Remove the Spread: Requesting no spread can reduce fat and calories without affecting the protein content.
Order Mustard Instead: Opting for mustard instead of the house spread can be another way to lower the fat and calorie count.
