Frequently Asked Questions about red onions and Keto

Are red onions keto-friendly?

Yes, red onions are keto-friendly. Although they contain carbohydrates, the quantity is usually not significant enough to interfere with the process of ketosis if consumed in moderation. Carbohydrates in vegetables like red onions are often balanced by their fiber content, resulting in a lower net carb value.

How many carbs are in red onions?

The carb content in red onions varies based on size. On average, a medium-sized red onion has around 8 grams of carbs. However, it is important to remember that not all of these carbs count towards your daily limit on a keto diet, thanks to the fiber content in red onions.

The net carb count of a red onion is calculated by subtracting the total fiber from the total carbs. A medium red onion, which contains roughly 8 grams of carbohydrates, also carries about 1.5 grams of fiber. As such, the net carbs would be 6.5 grams.

There isn’t a defined limit, but it’s important for those following a keto diet to be aware of their carb intake.
