Discovering In-N-Out's Lowest Calorie Options

For decades, In-N-Out Burger has maintained a simple, classic menu. While this simplicity is part of its charm, it can make navigating the menu for low-calorie options a challenge. The key to finding the lowest calorie item is understanding the concept of 'Protein Style,' a popular secret menu modification that substitutes a lettuce wrap for the traditional bun. This small change makes a significant difference in the final calorie count and is the most effective way to cut down on calories. Additionally, customizing your condiments by swapping the high-calorie spread for mustard and ketchup can save even more.

The Lowest Calorie Item: The Protein Style Hamburger

The standard Protein Style Hamburger is the undisputed lowest-calorie choice on the In-N-Out menu. It includes one beef patty, lettuce, tomato, and spread, all wrapped in fresh lettuce instead of a bun. While the regular hamburger with a bun contains around 390 calories, the Protein Style version significantly reduces that number to approximately 240 calories. The bun, according to nutritional breakdowns, is estimated to contribute around 160 calories alone. Therefore, eliminating the bun is the most impactful change you can make for calorie reduction.

How to Order for the Absolute Lowest Calorie Meal

To achieve the absolute minimum calories, consider ordering the Protein Style Hamburger with additional modifications. Ask for no spread and instead request mustard and ketchup. In-N-Out's signature spread adds an estimated 80 to 100 calories and 9 to 10 grams of fat, so eliminating it makes a substantial difference. For an even lower calorie count, ask for a "veggie burger"—which is a bun-less order of lettuce, tomato, and grilled onions—and add mustard only. Pair your low-calorie burger with water or unsweetened iced tea instead of a shake or soda.

Here is a step-by-step guide to ordering a minimal-calorie meal:

  1. Request a Protein Style Hamburger: This replaces the bun with a lettuce wrap, eliminating a large portion of calories and carbohydrates.
  2. Ask for Mustard Only (No Spread): Swapping the spread for mustard and ketchup saves significant calories and fat.
  3. Hold the Cheese: A single slice of cheese adds around 70 calories, so skipping it brings the calorie count down even further.
  4. Add Grilled Onions: For added flavor without many calories, ask for grilled onions.
  5. Choose a Zero-Calorie Drink: Water, unsweetened iced tea, or a diet soda will keep your total meal calories low.

Maximizing Flavor and Satisfaction on a Low-Calorie Diet
