If you are like me and garden, in the summer you’re probably buried in cucumbers. Even if you don’t garden, cucumbers are often a tempting vegetable because they are so affordable during the summer months. But, are cucumbers allowed on a keto diet?
Cucumbers are keto-friendly because they are very low carb. Even a large cucumber (8″ long) has only 4 net carbs, making cucumbers keto safe.
So now that we know that cucumbers are keto safe, let’s dig into the details about how many carbs are in cucumbers and how much cucumber is allowed on a ketogenic diet.

How Many Carbs Are In Cucumbers?
According to the U.S. Department of Agriculture’s FoodData Central Database, cucumbers are very low carb. As a mater of fact, I even included some cucumber recipes in my No Cook Keto Cookbook and it’s a must-have in my Keto Garden.
I’ve created a table below that includes how many carbs are in various serving sizes of cucumbers.
Table of Carbs In Cucumber By Serving Size
Serving Size | Total Carbs | Net Carbs |
---|---|---|
1 Cucumber Slice (7 g) | 0.151 g | 0.102 g |
Small Cucumber 6 3/8″ Cumber (158 g) | 3.41 g | 2.3 g |
