If you’re a newbie in the low-carb world, ketogenic dietary restrictions may leave you wondering what fruits and vegetables are keto and which ones aren’t. 

Starchy vegetables such as potatoes, yams, and even beets are not allowed on the ketogenic diet. They’re high in carbohydrates and eating just one portion may kick you out of ketosis and stall your weight loss goals or prevent you from getting all the health benefits a low carb diet provides.  But, what about cucumbers? How many carbs are in cucumbers and are they keto-friendly?

Are Cucumbers Keto and Low Carb?

They absolutely are! Aside from being ketogenic, cucumbers are mostly made up of water and are also a nutrient-dense food! Cucumbers are a good source of fat-soluble vitamin K, vitamin B, and other minerals. If you’re watching your weight, they’re perfect since they’re low in calories and you can eat them in a variety of different ways.

Cucumber Nutrition Information

A 100g portion of raw and unpeeled cucumber has: [1]

  • 15 calories
  • 0.11g fat
  • 0.65g protein
  • 3.63g carbohydrates
  • 0.5g fiber

How Many Net Carbs Are In Cucumbers? Are They Keto?

According to the FDA database, 100g of raw, unpeeled cucumber has 3.16g of net carbohydrates. [1]

One large cucumber (around 280g) has over 10g of total carbohydrates, so while it is definitely keto you still need to watch your daily intake and calculate your macros to stay in ketosis.

Cucumbers are definitely healthy and a great option for a midday snack, however carbs in cucumbers can add up quickly if you don’t keep track of how much you’re eating.
