Kombucha is a popular drink known for supporting your digestive system. 

One of the drawbacks of a ketogenic diet is that you can get stomach issues like constipation. So, it sounds like this drink might be a good solution for this issue. 

But, you might be wondering if kombucha is keto-friendly. 

This article will discuss everything related to this delicious drink and a ketogenic diet. Find out where it comes from and what it’s made of, how many grams of carbs it contains, if you are allowed to have it on a keto diet, and how much. We’ll also cover which types are best and what you can have it with. 

Let’s get this started!

 

What is kombucha?

Kombucha is a term to describe fermented tea. 

You start with a sweet base. It can be sweet tea or fruit juice with sugar. You then add a component called SCOBY, which means Symbiotic Culture of Bacteria and Yeast. 

Or, in simpler words, bacteria and yeast are added, then they use/ferment the sugar. 

During this fermentation process, the sugar is eaten by the bacteria and yeast (probiotics) and a gas is created as a byproduct. That is why it is a fizzy drink. 

Thanks to the addition of SCOBY, this beverage contains some probiotics and shares similar properties to sauerkraut, kimchi, and kefir. 

 

Kombucha nutrition facts

So now, let’s get into the good part. 

Let’s talk about the nutrition facts of this drink. How many carbs does it have? Is it high in calories?

Remember that each brand may have its own recipe, which means they can vary in nutritional value. However, here is a standard option for you to compare the macros and calories. 

Serving size: 100 mL

  • Calories: 17 kcal
  • Fat: 0 g 
  • Net carbs: 3 g
  • Total carbs: 3 g
  • Fiber: 0 g
  • Protein: 1.1 g

As you can see, it is a drink with a low calorie and carb content. 

Nonetheless, remember that this is for a serving size of 100 mL, which is slightly less than 1/2 cup. Many bottles and cans may have more than twice this amount, so you may not want to drink the whole bottle in one sitting.

It’s also essential to keep in mind that different brands can have a lower or higher carb content

The drink doesn’t have any fats or significant protein content, meaning you might need to add some to your meal to balance it. 


JUMPSTART YOUR KETO GOALS

 

Are you allowed to drink kombucha on keto?

Yes, kombucha can be keto-friendly, but it depends on the brand and how much you drink.

It varies depending on the amount of sugar it contains. Search for a type that has less than 3 grams of sugar per serving. 

If you get one with a higher carb content, you should be decreasing the portion size or reducing other carbs sources throughout the day to avoid affecting your goals. 

However, if it only has 3 grams of sugar or less, this is not a high intake that can affect your ketosis levels, as long as you are careful with the portion size. 

This brings us to the next question. 

 

How much kombucha can you have on a keto diet? 

The quantity of kombucha depends on the number of carbs you can consume throughout the day. 

For example, if you want to stay below 50 g of net carbs per day, you can have 1 cup (240 ml) of this drink. This would give you 7.2 g of net carbs. 

The more kombucha you drink, the more you need to decrease the number of carbs in other food options to compensate and avoid coming out of ketosis. 

 

What kind of kombucha can you have on keto?

It bears repeating that the number of carbs in kombucha depends on the brand. Some brands have more, while others have less. 

Even within the same brand there are different flavors, so you really need to check the label each time.

Generally the most keto-friendly kombucha flavors are original or ginger. Drinks with fruit juices tend to be higher in carbs.

 

BUILD YOUR KETO DIET PLAN

 

What can you drink kombucha with?

Since it already has some carbs, for the meal you want to focus on non-starchy vegetables, protein, and healthy fats. 

For example, you can have a glass of this drink along with some salmon, green salad, and avocado. Here you have the carbs from the drink, protein from the salmon, fiber from the vegetables, and fat from the avocado. 

You can also have it as a snack with some Greek yogurt or a couple of nuts. 

The most essential thing is to balance out the carb content in the drink with other low-carb options.
