A medium-sized banana typically contains around 24g of total carbohydrates, including about 3g of fiber.

To calculate the net carb, subtract the fiber from the total carbohydrates.

This gives you approximately 21g of net carbs per medium banana.

Net carbs are the carbohydrates that are absorbed by the body and can affect blood sugar levels.

It's essential for those monitoring their carbohydrate intake, such as individuals following a ketogenic diet or managing diabetes, to consider net carbs in their dietary planning.

Additionally, the exact number can vary slightly depending on the banana's size and ripeness.
