Does green juice have carbs?

Green juice has become an increasingly popular health drink in recent years. Made by juicing leafy greens and vegetables, green juice provides a concentrated dose of nutrients in an easy-to-digest form. But with all the natural sugars found in veggies and fruits, many people wonder: does green juice have carbs?

The answer is yes – green juices do contain carbohydrates. However, the amount can vary widely depending on the specific ingredients used. By choosing low-sugar veggies and minimizing high-carb fruits, it’s possible to make green juice with a relatively low carb count.

Carbohydrates in Common Green Juice Ingredients

Let’s take a look at the carb content of some typical green juice ingredients:

Ingredient Serving Size Total Carbs
Kale 1 cup chopped 7 g
Spinach 1 cup 1 g
Cucumber 1 cup sliced 4 g
Celery 1 stalk 3 g
Ginger 1 Tbsp grated 3 g
Lemon 1 medium 11 g
Apple 1 medium 25 g
Pineapple 1 cup chunks 17 g

As you can see, carb content can range quite a bit depending on the specific ingredients. Leafy greens like kale and spinach have fewer carbs, while fruits like apples and pineapple have significantly more.

Fiber Content of Green Juices

In addition to total carbs, it’s also helpful to look at the fiber content of green juice ingredients. Fiber moves through the body undigested, so it doesn’t count toward the total carb value:

Ingredient Total Carbs Fiber Net Carbs
Kale 7 g 2 g 5 g
Spinach 1 g 1 g 0 g
Cucumber 4 g 1 g 3 g
Celery 3 g 2 g 1 g
Ginger 3 g 1 g 2 g
Lemon 11 g 2 g 9 g
Apple 25 g 4 g 21 g
Pineapple 17 g 2 g 15 g

By considering the fiber content, you can see that the total digestible carb count of many green juice ingredients is lower than the total carbs.

Strategies to Reduce Carbs in Green Juice

If you’re looking to lower the carb content of your green juice, here are some tips:

  • Use leafy greens as the base. Kale, spinach, chard, lettuce, and other greens are very low in sugar and carbs.
  • Increase veggies like cucumber, celery, zucchini, and fennel that add volume with fewer carbs.
  • Limit higher glycemic fruits like pineapple, mango, grapes, and banana.
  • Add lemon/lime juice instead of fruit for flavor.
  • Stay away from starchy vegetables like beet and carrot which are higher in carbs.
  • Use small amounts of low sugar fruits like berries and green apple.
  • Opt for herbal teas and unsweetened nut milk instead of fruit juice as the liquid base.

Sample Low Carb Green Juice Recipe

Here is an example of a green juice recipe designed to be lower in carbs:

Ingredient Amount
Cucumber 1 cucumber
Kale 2 cups
Celery 2 stalks
Lemon 1/2 lemon
Ginger 1 inch knob
Ice 1 cup
Water 1 cup

Based on the nutrition info above, this green juice would contain approximately:

Total Carbs Fiber Net Carbs
18 g 8 g 10 g

So despite using several vegetables, the total carb count remains low at 10g net carbs for this 16 oz green juice.

The Caveats of Juicing for Carbs

It’s important to keep in mind that juicing removes the fiber content of whole fruits and vegetables. The carb information provided above is based on blended juices containing pulp and fiber.

If you use a juicer that extracts the liquid and leaves behind the pulp, the fiber content will be greatly reduced. This means the net carb count of the juice will be closer to the total carbs.

For example, juicing an apple in a centrifugal juicer may yield a juice with 20-25g total carbs and only 1-2g fiber. So the net carbs of extracted apple juice would be around 22-24g per apple.

Green Juice vs Smoothies for Carbs

There is an ongoing debate in the health world about green juices versus green smoothies. Smoothies retain all the fiber from the whole fruits and vegetables. Juices remove most of the insoluble fiber.

This fiber content is a key distinction when comparing carbs in green juices and smoothies:

  • Green smoothies: All the fiber is retained from the ingredients, so net carbs = total carbs – fiber.
  • Blended green juices: Pulp is included so some fiber remains. Net carbs = total carbs – remaining fiber.
  • Extracted green juices: The insoluble fiber is removed. Net carbs ≈ total carbs.

For someone tracking net carbs, green smoothies made with low carb ingredients would generally have a lower digestible carb count compared to extracted green juices using the same produce.

Should You Drink Green Juice on a Low Carb Diet?

Green juice can certainly fit into a low carb eating pattern like the ketogenic diet. However, it requires careful selection of low sugar vegetables along with minimal amounts of fruits and starchy veggies.

Here are some tips for low carb green juicing:

  • Stick with greens like spinach, kale, chard, lettuce as the base.
  • Include non-starchy veggies like cucumber, zucchini, celery, fennel.
  • Use lemon/lime for flavor instead of sugary fruits.
  • Limit higher carb vegetables like carrots and beets to small amounts.
  • Avoid all sweet fruits like mangos, pineapples, bananas, grapes.
  • Only use berries in small portions if you want some fruit.

With the right vegetable choices and proportions, green juices can definitely be low carb. Getting them as close to zero net carbs as possible provides the biggest benefit for a keto diet.

Focusing on lower sugar vegetables, using small amounts of fruit, and opting for blended juices retains more fiber and yields a lower net carb drink.


Green juices can contain a wide range of carbohydrate content based on the specific ingredients used. Leafy greens and non-starchy vegetables provide fewer digestible carbs, while fruits and pulpy veggies have more sugar and carbohydrates.

Choosing low glycemic veggies as the base of your juice and minimizing high sugar fruits allows you to make green juice that is relatively low in net carbs. Using a blender instead of juicer also retains valuable fiber to further reduce the digestible carb content.

With thoughtful ingredients and preparation, green juices can be incorporated into a low carb or ketogenic diet. Prioritize greens over fruits, use low sugar produce, and blend instead of extract juices to maximize nutrition while minimizing carbs.
