At Taco Bell, choose a single Crunchy Taco with a Fire Sauce packet and water if it fits your carb budget. It’s a small order, so don’t expect a filling dinner. Skip the standard Cantina Chicken Bowl, quesadillas, chips and potatoes for a lower-carb stop.
All figures below come from Taco Bell’s Full Nutrition Information page, retrieved October 24, 2026. Its embedded nutrition table says Last Updated: October 22, 2026. Values are as published by the chain; net carbs are total carbs minus published fiber, and standard-item values include the standard item.
What you can count without guessing
| Item and serving | Calories | Total carbs | Fiber | Net carbs | Protein |
|---|---|---|---|---|---|
| Crunchy Taco, 1 | 170 | 13g | 3g | 10g | 7g |
| Nacho Cheese Doritos Locos Taco, 1 | 170 | 13g | 3g | 10g | 7g |
| Crunchy Taco Supreme, 1 | 190 | 16g | 3g | 13g | 8g |
| Nacho Cheese Doritos Locos Taco Supreme, 1 | 190 | 15g | 3g | 12g | 8g |
| Cantina Chicken Bowl, standard | 580 | 55g | 11g | 44g | 26g |
| Chicken Quesadilla, standard | 490 | 44g | 4g | 40g | 26g |
| Breakfast Quesadilla with Bacon, standard | 500 | 42g | 3g | 39g | 25g |
A Crunchy Taco lists 13g total carbs and 3g fiber, giving 10g net. Count the whole taco, shell included.
I would choose the Crunchy Taco with a Fire packet for a simple small order. Skip the Supreme upgrade if keeping the carb count down is the priority.
The standard Cantina Chicken Bowl lists 55g carbs and 11g fiber, or 44g net. You can ask to remove rice and beans, but Taco Bell’s nutrition info doesn’t give that custom total or a tortilla-free quesadilla total.
Sides, sauce packets and coffee
| Item and serving | Calories | Total carbs | Fiber | Net carbs | Protein |
|---|---|---|---|---|---|
| Black Beans, 1 side | 50 | 7g | 4g | 3g | 3g |
| Black Beans & Rice, 1 side | 160 | 25g | 5g | 20g | 4g |
| Chips and Nacho Cheese Sauce, 1 order | 220 | 24g | 2g | 22g | 3g |
| Cheesy Fiesta Potatoes, 1 order | 240 | 29g | 3g | 26g | 3g |
| Fire Sauce, 1 packet | 0 | 0g | 0g | 0g | 0g |
| Hot Sauce, 1 packet | 0 | 0g | 0g | 0g | 0g |
| Mild Sauce, 1 packet | 0 | 0g | 0g | 0g | 0g |
| Diablo Sauce, 1 packet | 0 | 0g | 0g | 0g | 0g |
| Premium Roast Coffee, hot, plain | 0 | 0g | 0g | 0g | 0g |
| Cinnabon Delights Coffee, hot | 160 | 34g | 0g | 34g | 1g |
Black Beans alone list 7g total carbs and 4g fiber, or 3g net. Black Beans & Rice lists 25g total and 5g fiber, or 20g net. Choose the beans-only side if that portion fits your remaining budget.
Chips and Cheesy Fiesta Potatoes belong on the skip list for a low-carb order. Cheese is allowed to have friends, but it doesn’t cancel the potatoes and chips they arrive with.
Mild, Hot, Fire and Diablo packets each list 0g carbs. Pick one of those named packets for the orders below.
Plain hot Premium Roast Coffee publishes 0 calories and 0g carbs. The hot Cinnabon Delights Coffee lists 34g carbs. Calling both of them coffee doesn’t make them interchangeable. Order the plain version without additions if you’re using its count.
Complete orders, counted
The first four rows are small taco orders with the shells included. Compare their totals with your remaining carb budget. The final two rows show standard high-carb combinations to skip.
| Order | Calories | Total carbs | Net carbs | Protein |
|---|---|---|---|---|
| Small: 1 Crunchy Taco + Fire packet + Water | 170 | 13g | 10g | 7g |

| Small: 1 Nacho Cheese Doritos Locos Taco Supreme + Diablo packet + Water | 190 | 15g | 12g | 8g |
| Comparison: Cantina Chicken Bowl + Chips and Nacho Cheese Sauce + Water | 800 | 79g | 66g | 29g |
| Comparison: Chicken Quesadilla + Cheesy Fiesta Potatoes + Water | 730 | 73g | 66g | 29g |
Double the tacos or add a side and the total goes up too. Count every additional item.
If a small taco uses more carbs than you want to spend on a snack, choose another restaurant for a more substantial meal.
How to order
- Choose a Crunchy Taco or another named taco above if its whole-item carbs fit your budget.
- Keep the standard taco build when using the totals above.
- Count each additional taco as another full serving.
- Choose a named Mild, Hot, Fire or Diablo packet, and skip Chips and Cheesy Fiesta Potatoes.
- Choose Water or plain Premium Roast Coffee.
- Check the final order for default sides and additions.
Breakfast: skip the quesadilla
Taco Bell lists breakfast as regional. Its Bacon Breakfast Quesadilla lists 42g total carbs and 3g fiber as sold, so I’d leave it off a low-carb breakfast order.
