Parsnips are delicious and have a natural earthy flavor—those on a low carb diet might be tempted to include them in their meal plan, but may stop and ask themselves, “how many carbs are in parsnips?” just like they do before eating any other food. 

The unfortunate truth is that this root vegetable that resembles carrots could is not keto but a closer look at their carb contents and 7 keto friendly root vegetables will leave you with an idea on how much parsnip you can eat, and substitutes too.

Is Parsnip Keto? Are Parsnips Keto Approved? Can Someone Have Parsnip on Keto?

Parsnips are a starchy root vegetable that are not keto and certainly not approved to be on a keto diet. This is because they have a high carb content and have very low levels of fat—two macro traits that are not desirable when someone is looking for foods to include in a keto diet.

A ketogenic diet which is among the nation’s hottest trending diets requires those who are partaking in to ingest low amounts of carbs, high amounts of fat and moderate quantities of protein.1

The carb content of these vegetables is nearly half of keto diets daily allotment. Point being, someone on a keto diet must consume between 20 and 50 grams of net carbs on a daily basis to remain in a state of ketosis (based on a 2000 kcal diet)—where the body breaks down the fat into ketones to be used as an energy source instead of glucose in what is termed as ketosis.2

Can someone have parsnips on keto? With such high carb content, it is easy to see why including parsnips in a keto diet would not be a good idea as they may easily throw the body off ketosis defeating the purpose of a keto diet. I

While parsnips aren’t keto, diets could eat 1/3 – 1/2 a cup if they’re cautious to make a parsnip keto by only eating a small serving.  

How Many Carbs Are in Parsnip: Keto or Not?

Parsnips are a starchy root and as a consequence, have a high amount of carbs present; as per the United States Department of Agriculture, a raw serving of 133 grams has a colossal 23.9 grams of total carbs.3 This easily exceeds the minimum amount of carbohydrates that can be consumed by those on a keto diet which rules out parsnips as a keto friendly vegetable. 

To consume parsnip keto style, someone will need to eat the vegetable throughout the day and not in one sitting. They will need to ensure that it remains as the only source of carbs on the day; in this way, parsnips can be enjoyed by those on a keto diet.

Alternative Root Vegetables That Are Low in Carbs
