Nutritionists Reveal Healthiest In-N-Out Order

Nutritionists have identified the healthiest order at In-N-Out Burger, emphasizing lean protein and vegetable components while cautioning against high-sugar items like milkshakes. The recommended meal prioritizes a Double-Double, prepared "protein style" (without the bun), and paired with a side of fries cooked well-done to reduce oil content. This combination offers a substantial protein source with fewer carbohydrates and fats compared to standard burger meals.
The advice, shared by registered dietitians and nutrition experts, highlights the importance of mindful ordering even at fast-food establishments. They suggest opting for grilled chicken sandwiches or the standard hamburger as alternatives, though the Double-Double protein style is often cited for its balanced macronutrient profile. The inclusion of lettuce, tomato, and onion in the Double-Double adds essential vitamins and fiber, contributing to its nutritional value.
When it comes to sides, the well-done fries are a strategic choice to minimize oil absorption. Alternatively, customers can request their fries steamed, which further reduces fat content. For beverages, water or diet soda are recommended over the chain's popular milkshakes, which are high in sugar and calories. This guidance aims to help consumers make more informed decisions that align with healthier eating habits, even when dining out.
Experts also note that customization is key. Requesting no spread on the burger can significantly cut down on fat and calorie intake. While In-N-Out does not offer a dedicated "healthy" menu, these nutritionist-approved modifications allow for a relatively balanced meal. The focus remains on maximizing nutrient density while minimizing processed ingredients and added sugars, making the Double-Double protein style a top contender for the healthiest fast-food option.
