Arby's Double Roast Beef Sandwich Carb Breakdown

The total carbohydrate count for a single Arby's Double Roast Beef sandwich is 38 grams. While this number provides the overall picture, a deeper look at the nutritional details is required for those who are carb-conscious, especially if they are tracking net carbs.

The Source of Carbs: The Sesame Seed Bun

For any fast-food sandwich, the bun is almost always the primary source of carbohydrates. With the Double Roast Beef sandwich, the classic sesame seed bun is where the bulk of those 38 grams are found. The signature roast beef itself is very low in carbohydrates, consisting mostly of protein and fat. This is a crucial distinction for those on a strict low-carb or ketogenic diet, as it offers a simple path to drastically reduce the carb intake.

Classic Roast Beef	35	27	32
Double Beef 'n Cheddar	48	39	46
Half Pound Roast Beef	38	48	36

As the table clearly shows, the carbohydrate content of different roast beef options varies significantly, particularly when comparing the double sandwiches with and without the bun.

Strategic Ordering: How to Reduce Carbs at Arby's

For health-conscious diners, enjoying Arby's without derailing dietary goals is possible with a few simple strategies. Here is a list of ways to make your meal lower in carbs:

Go bunless: As mentioned, this is the most effective and straightforward method. The roast beef itself is high in protein and low in carbs, making it an excellent foundation for a satisfying, low-carb meal. You can request the roast beef in a bowl or a lettuce wrap.
Hold the sauce: Arby's Sauce and Horsey Sauce can contain added sugars, contributing to the total carb count. Opting out of these or asking for a very small amount can help. Better yet, bring your own low-sugar condiment if possible.
Avoid certain sides: Skip the fries, which are a major source of carbohydrates, and choose a side salad with a low-carb dressing instead.
Scrutinize add-ons: Be mindful of other toppings. While lettuce and onions are fine, some items like the Beef 'n Cheddar's cheese sauce will increase both carbs and calories.

The Role of Protein and Satiety

Beyond just carbs, the Double Roast Beef sandwich is notable for its high protein content, clocking in at 38 grams. Protein is a vital macronutrient for building and repairing tissues and plays a significant role in satiety, or the feeling of fullness. The substantial protein in this sandwich can help keep you satisfied for longer, which can be beneficial for managing overall food intake. For those on a low-carb diet, prioritizing high-protein sources like the roast beef itself is key to feeling full and energized.

Conclusion: The Bottom Line on Carbs

Ultimately, how many carbs are in an Arby's double roast beef sandwich depends on how you order it. The standard sandwich delivers 38g of total carbs, largely from the bun. However, savvy consumers have a clear pathway to drastically reduce this number by ordering the meat without the bun. By understanding the nutritional composition and making strategic substitutions, you can enjoy the flavor of Arby's while keeping a close eye on your carbohydrate intake.
