Kombucha And Keto: Friends Or Foes?

Kombucha is a fermented health drink made from tea, bacteria, yeast, and sugar. The keto diet, on the other hand, is a low-carb, high-fat diet. So, can you drink kombucha and remain in ketosis? The answer is yes, but only if consumed in moderation and if it's a low-sugar variety.

Kombucha is keto-friendly if consumed in moderation

Kombucha is a fermented health beverage with ample health benefits. It is made by adding a SCOBY (symbiotic culture of bacteria and yeast) and kombucha starter tea to room-temperature, freshly brewed sweet tea. The keto diet, on the other hand, is a low-carb, high-fat diet that puts your body into a state of ketosis, where it burns fat as fuel instead of carbohydrates. So, can you drink kombucha and stay in ketosis? The answer is yes, if consumed in moderation.

However, not all kombucha is created equal. The amount of sugar remaining in the kombucha will vary depending on how long it was brewed, the amount of sugar it started with, and other variables related to the brewing process. When purchasing store-bought kombucha, check the labels to see the exact amount of carbohydrates and sugar per serving. The range is typically between 6-12 carbs per 8oz serving, so even at 6 carbs, that's a significant portion of your daily keto allowance. Therefore, it's best to stick to a 4oz serving or less.

If you're brewing your own kombucha, you can ensure it's keto-friendly by fermenting it for a full 21-30 days. The longer fermentation period allows the yeast to consume more sugar, resulting in a lower-sugar, lower-carb drink. However, be mindful that the longer the fermentation, the stronger and more acidic the kombucha will become. To counteract this, you can dilute the kombucha with seltzer water or flavour it with keto-approved sweeteners like stevia.

In conclusion, kombucha can be a part of a keto diet if consumed in moderation. Whether you're buying store-bought or brewing your own, always check the sugar and carbohydrate content to ensure it aligns with your keto goals.

The longer the fermentation, the less sugar it will contain

Kombucha is a fermented drink made from sweet tea. The fermentation process is what gives kombucha its gut-balancing properties, similar to those found in healthy fermented foods like unpasteurised kimchi, sauerkraut, and miso soup.

The fermentation process also consumes much of the sugar in the tea. The longer the fermentation, the more sugar is consumed, leaving less sugar in the final product. This is why the length of fermentation is an important consideration for those on a keto diet, which is a low-carb, high-fat diet that forces the body to burn stored blood sugar and break down protein and fat for rapid weight loss.

The longer the kombucha is left to ferment, the less sugar it will contain. For example, kombucha that has been left to ferment for 70 days will become kombucha vinegar, which has a sugar content of 0-2.5g per 250ml. However, the less sugar in the kombucha, the more vinegary the taste. Therefore, those brewing kombucha at home will need to find a balance between the amount of sugar and the taste they prefer.

For a 1-gallon batch of kombucha brewed at the optimal temperature (75-85°F), most people find the most delicious flavour between 7-14 days. However, the longer the brew is left, the lower the sugar levels. Brewing for 21-30 days will produce a much lower sugar content, around half of a normal brew.

Home-brewed kombucha often contains fewer carbs

The best way to ensure that your kombucha is low-carb is to ferment it for a full 21-30 days. The yeast will continue to consume sugars until the end of the fermentation, leaving less and less as time goes on. The longer the fermentation goes on for, the stronger the kombucha gets. You shouldn't drink super mature kombucha directly as it is highly acidic and could be harmful to your health. Instead, dilute the kombucha with flavoured or plain seltzer water.

If you are brewing your own kombucha, you can also control the amount of sugar used. Using less sugar to start with will lower the residual amounts after brewing. However, this will also deplete the nutrients for the organisms which will impact the flavour, making for a weaker brew and SCOBY.

If you are serious about remaining in ketosis, get yourself a ketone test kit. Everyone's body is a little different, so testing is the only way to be sure.

Commercially available kombucha may not be keto-friendly

Kombucha is a fermented health beverage that is made by adding a SCOBY (symbiotic culture of bacteria and yeast) and kombucha starter tea to room-temperature, freshly brewed sweet tea. The keto diet, on the other hand, is a low-carb, high-fat diet. So, can kombucha be consumed while on a keto diet? The answer is: it depends.

Firstly, all kombucha has sugar as it is fermented sweet tea, and the sugar in the tea feeds the yeast and bacteria. However, most of the sugar is consumed by the SCOBY during the fermentation process. The remaining amount of sugar depends on the manufacturer. If the manufacturer chooses to add more sugar to sweeten the brew or to ferment the brew in a second fermentation process, this will add more sugar and carbohydrates, making the kombucha unsuitable for a keto diet.

Therefore, commercially available kombucha may not be keto-friendly. The sugar content depends on the manufacturer and the specific brewing process. Some commercial brands of kombucha choose to do a double fermentation process, which adds flavours and fruits to mask the vinegary taste of natural kombucha. This additional fermentation process results in higher levels of carbohydrates and sugar, making the kombucha unsuitable for a keto diet.

To ensure that kombucha is keto-friendly, it is important to check the labels and understand the serving size for the listed sugar and carb content. The general guideline for remaining in ketosis is to consume less than 20-50 net carbohydrates per day. For keto dieters, the recommended daily allowance of net carbs ranges from 20 to 100 grams. Thus, it is crucial to check the nutritional information on the label to determine if a particular brand of kombucha fits within your keto diet.

In conclusion, while kombucha can be keto-friendly if it has low sugar and carbohydrate content, commercially available kombucha may not always be suitable for a keto diet due to the potential for higher sugar and carbohydrate levels. It is important to carefully read labels and understand serving sizes to make an informed decision about whether a specific kombucha brand aligns with your keto diet goals.

The type of tea used does not affect its keto-friendliness

Kombucha is a fermented tea drink that has become increasingly popular in recent years, especially among those following a ketogenic (keto) diet. The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates.

The main concern when it comes to kombucha and keto is the sugar content. Kombucha is typically made with a sweet tea base, which can be a combination of black or green tea and sugar. This sugar is necessary for the fermentation process, as it is food for the SCOBY (symbiotic culture of bacteria and yeast) that ferments the tea.

The type of tea used does not significantly affect the keto-friendliness of kombucha. Whether it's black, green, or any other type of tea, the fermentation process will consume most of the tea's sugar. The SCOBY breaks down the sugar into glucose and fructose, and any sugars left over will be fructose, which is harder for the SCOBY to break down. Therefore, the longer the fermentation process, the less sugar will be present in the final product, regardless of the type of tea used.

To make kombucha more keto-friendly, it is recommended to brew it for a longer period, typically between 21 and 30 days. This extended fermentation allows the SCOBY to consume more sugar, resulting in a lower sugar and carbohydrate content. However, a longer fermentation also leads to a stronger, more vinegar-like taste, so there is a trade-off between carb content and flavour.

Additionally, diluting kombucha with water or flavoured seltzer water can help reduce the acidity and improve the taste without adding extra carbs. Using different tea blends, such as rooibos or hibiscus tea, can also add natural sweetness and flavour without increasing the sugar content.

When purchasing store-bought kombucha, it is important to read the labels to check the carbohydrate and sugar content. The range is typically between 6-12 carbs per 8oz serving, but some brands may have lower sugar content, making them more suitable for a keto diet.
