Understanding How Many Carbs Are in a Foot Long Flatbread from Subway?

4 min read

According to nutrition data updated in March 2025, a 6-inch Subway flatbread contains 24 grams of carbohydrates, which means a standard footlong flatbread contains approximately 48 grams of carbohydrates from the bread alone. For those managing their intake or tracking macros, understanding how many carbs are in a foot long flatbread from Subway? is a crucial first step in making an informed dietary choice. The total carb count of your sandwich, however, will be significantly higher depending on the fillings and sauces you choose.

Quick Summary

The carb count for a footlong flatbread is about 48 grams, but this number varies significantly once fillings are added. This article breaks down the nutritional content of the bread itself, compares it to other Subway bread options, and provides tips for building a lower-carb sandwich, explaining how toppings, cheese, and sauces affect the final nutritional value.

Key Points

  • Bread-Only Carb Count: A footlong flatbread contains approximately 48g of carbohydrates from the bread itself, based on recent 6-inch serving data.

  • Fillings Add Significantly More: The final carbohydrate total will be much higher with toppings, cheese, and sauces, with some footlong subs exceeding 80-90g of carbs.

  • Flatbread vs. Other Breads: Compared to other breads, the flatbread is a lower-calorie option but not necessarily the lowest in carbs, depending on the variety.

  • Build a Low-Carb Sandwich: To reduce carbs, focus on loading up on fresh vegetables, choosing lean protein, and opting for zero-sugar sauces instead of sweet ones.

  • 'Sub in a Tub' Alternative: For a very low-carb meal, consider ordering your sandwich ingredients as a salad, effectively eliminating the bread.

  • Glycemic Load Matters: The type of carbs and what you eat them with affects blood sugar. Pairing carbs with protein and fat can create a more balanced meal.

  • Check Official Information: Nutritional data can vary by region and change over time, so always check the official Subway website for the most up-to-date information.

Deconstructing the Subway Flatbread: Carbohydrate Breakdown

For many health-conscious consumers, Subway is seen as a fast-food alternative with seemingly lighter options. However, the nutritional profile of a Subway sandwich, especially the carbohydrate content, can vary drastically depending on the bread and fillings selected. The popular flatbread is often a point of curiosity for those counting carbs. Based on recent nutrition information, a standard 6-inch serving of Subway's plain flatbread contains approximately 24 grams of total carbohydrates. Since a footlong sub is composed of two 6-inch servings, the bread itself contributes about 48 grams of carbohydrates to your meal. It is important to note that this figure does not include any cheese, meat, vegetables, or sauces, all of which will add to the final total.

The Role of Fillings and Toppings

The most significant factor in determining the total carbohydrate count of a footlong flatbread sandwich is the combination of ingredients. While the plain bread is the foundation, your choice of fillings can easily double or triple the carbohydrate content. For example, a footlong Egg & Cheese flatbread sandwich is reported to contain 84 grams of carbs in total, with some variants like the Steak, Egg & Cheese reaching 90 grams. Even a footlong Turkey Avocado flatbread is listed with 88 grams of carbs. This highlights how additions like cheese and certain protein preparations can add to the total. Sauces, especially sweet ones like Sweet Onion Teriyaki, can also be packed with sugar, further increasing the carb count.

Comparison of Subway Bread Options

To put the flatbread's carb count into perspective, it's helpful to compare it to other bread options available at Subway. The nutritional data can fluctuate, but the following table provides a general comparison based on available information for a 6-inch serving.

Bread Type (6-inch) Calories Carbs (g) Fiber (g) Protein (g)
Flatbread 140 (approx) 24 1 4
9-Grain Wheat 210 40 - 8
Hearty Italian 210 40 - 7
Italian (White) 200 38 - 7
Italian Herbs & Cheese 240 41 - 9

Note: Nutritional information can change. Always check the latest data on the Subway website or app for the most accurate figures.

From this table, we can see that while the flatbread is among the lowest in calories for a 6-inch serving, its carbohydrate count is not necessarily the lowest. The plain Italian bread, for instance, has slightly fewer carbs per 6-inch serving. However, the flatbread is a popular choice for those mindful of their calorie intake.

How to Build a Lower-Carb Flatbread Sub

For those watching their carbohydrate intake, a footlong sub can be a significant portion of a day's carb allowance. However, there are several ways to build a more carb-conscious flatbread sandwich. Here are some actionable tips:

  • Load up on veggies: Adding extra non-starchy vegetables like lettuce, cucumbers, green bell peppers, and spinach can increase the volume and fiber of your meal without adding many carbs.
  • Choose lean protein: Opt for lean proteins like turkey breast or chicken strips, which add significant protein to increase satiety and slow carbohydrate digestion.
  • Be mindful of cheese: While cheese adds flavor and fat, it also contains some carbs. Using less or skipping it can help reduce the total.
  • Select zero-sugar sauces: Avoid sugary sauces like Sweet Onion Teriyaki. Instead, choose low-carb options like mustard, oil, vinegar, or a light vinaigrette.
  • Consider a 'Sub in a Tub': For a very low-carb option, many Subway locations offer a 'Sub in a Tub' or salad, which includes all the sandwich fillings but without the bread.

The Impact of Carbohydrate Quality

Not all carbohydrates are created equal. While the flatbread provides carbs, it's not the same as a whole-grain option. Subway's whole-grain bread, while it may have a higher carb count, typically contains more fiber. Dietary fiber slows the absorption of sugar into the bloodstream, preventing a rapid spike in blood sugar levels. For individuals with diabetes or those seeking sustained energy, this glycemic load is a crucial factor to consider. Pairing the carbs from the flatbread with protein and healthy fats from your fillings can help mitigate the blood sugar impact.

Conclusion: Making an Informed Choice

Determining how many carbs are in a foot long flatbread from Subway? is only one piece of the dietary puzzle. The flatbread itself contributes a moderate amount of carbohydrates, but the full nutritional picture depends heavily on your choice of fillings, sauces, and additional ingredients. By being mindful of your additions and considering lower-carb alternatives like the 'Sub in a Tub', you can enjoy a Subway meal that aligns with your nutritional goals. Always check the most current nutritional information provided by Subway to ensure you are making the best choice for your diet.

Sauces can significantly increase the total carb count, especially sugary varieties like Sweet Onion Teriyaki. For example, a footlong Sweet Onion Chicken Teriyaki on flatbread can have over 100g of total carbs. Using zero-sugar or low-carb options like mustard or vinegar is a better choice for carb management.

For those seeking a very low-carb meal, the best alternative is to order your sandwich ingredients as a 'Sub in a Tub,' or salad. This allows you to get all the protein and vegetable fillings without the bread.

Yes, they can. While the plain flatbread has a certain carb count, varieties like the multigrain flatbread or flavored options such as Jalapeno Cheese or Italian Herbs & Cheese have different nutritional profiles. It's crucial to specify which type of flatbread you're inquiring about and check the specific nutrition information.

Beyond just choosing the flatbread, you can significantly reduce your overall carb intake by focusing on the fillings. Add extra vegetables, opt for lean meats, go easy on the cheese, and choose low-carb condiments like mustard, oil, and vinegar. Eating a 6-inch sub instead of a footlong is also an easy way to halve the carb count from the bread.

Absolutely. Lean meats like turkey or chicken add protein, while high-carb fillings like Egg & Cheese or Steak, Egg & Cheese add a substantial amount of carbohydrates and other macros. Be sure to check the nutritional information for the specific combination you order.

Most of the carbohydrates in the flatbread are simple, coming from refined flour. Unlike whole-grain breads that contain more fiber to slow digestion, the carbs in flatbread can lead to a quicker blood sugar spike, especially when not paired with protein and fiber.
