Net carbs
One serving of nachos with cheese has about 25g of net carbs, total carbs (28g) minus fiber (3g). See the net carbs guide.
For diabetes
An 80g serving of nachos has 28g of carbs. A typical sports-bar or restaurant nacho plate runs 300 to 400g and carries 100 to 130g of carbs. Beans, sour cream, and guacamole toppings add fiber and fat but also add carbs. Salsa is low-carb. The corn chips are the primary carb driver. See the diabetes carb-counting guide.
Keto and low carb
A standard nachos serving has 25g of net carbs, which is too much for strict keto. Restaurant portions can exceed 100g of net carbs easily. Nachos do not fit keto.
Good to know
Tortilla chips used for nachos have about 15g of carbs per 1-oz serving (about 10 to 12 chips). A restaurant nacho plate typically contains 3 to 4 oz of chips plus cheese, which means 45 to 60g of carbs from chips alone before any toppings. Cheese adds protein and fat but minimal carbs. Beans add 15 to 20g of carbs per 1/4 cup. Guacamole adds about 1 to 2g of net carbs per two tablespoons.
