Is Balsamic Vinegar Keto-Friendly?

author avatar Dr. Eric Berg 08/30/2023

Balsamic vinegar is a popular Italian condiment often mixed with olive oil to make balsamic vinaigrette and other salad dressings. But is balsamic vinegar keto-friendly? 

Traditional balsamic vinegar tends to be relatively low in carbs and can be enjoyed in moderation on a ketogenic diet. However, commercial balsamic vinegar and balsamic glazes are often packed with sugar and can contain up to 18 grams of net carbs per tablespoon.

Learn why some balsamic vinegar can quickly push you out of ketosis and discover the best keto-friendly alternatives.

Can you have balsamic vinegar on keto?

Whether you can have balsamic vinegar on keto depends on the carb content of the specific balsamic product you plan to use. 


Balsamic vinegar is made by boiling down and fermenting concentrated grape juice, creating a dark vinegar with a sweet and tangy flavor. However, not all carbs are broken down during the fermentation process, which explains why most balsamic vinegar contains some amounts of residual sugars.

“Depending on the quality of the grape juice, fermentation method, and aging period, the carb content of specific balsamic vinegar brands can differ significantly,” explains Dr. Berg. 

How many carbs are in balsamic vinegar? 

Regular balsamic vinegar and white balsamic vinegar varieties contain between two to ten grams of carbs per one tablespoon (15 ml) serving. However, some low-carb versions are available that contain less than two grams of net carbs per serving.

Balsamic glaze is a highly concentrated form of balsamic vinegar with a thick and syrupy consistency, often used as a drizzle or sauce to add flavor and decoration to dishes. 

Most commercially produced balsamic glaze is sweetened with sugars and thickened with syrups or caramel and can contain as many as 18 grams of carbs per tablespoon. 

It’s important to check labels and opt for low-carb balsamic products that won’t interfere with ketosis and disrupt fat burning.

Alternatively, opt for carb-free vinegar options such as:

  • Red wine vinegar 

  • White wine vinegar 

  • White vinegar

  • Apple cider vinegar 

Watch the video below to discover the difference between balsamic vinegar and apple cider vinegar on keto.

Balsamic vinegar vs. apple cider vinegar on keto

Apple cider vinegar is generally considered more keto-friendly than balsamic vinegar due to its minimal carbohydrate content.

Apple cider vinegar contains less than one gram of net carbs per tablespoon, which makes it an excellent low-carb alternative to balsamic vinegar.

And, what’s more, apple cider vinegar works great for weight loss, supports digestion and mineral absorption, speeds up keto-adaptation, and promotes healthy blood sugar regulation. 

But does apple cider vinegar break a fast? No, it doesn’t! Apple cider vinegar is safe to have while fasting and may even enhance your fasting results.

How much balsamic vinegar can I have on keto?

How much balsamic vinegar you can have on keto depends on its carb content and your daily net carb limit.

“One tablespoon of low-carb balsamic vinegar may not disrupt fat-burning and ketone production if you can maintain ketosis by limiting your net carb count to 50 grams daily.

However, if you consume no more than 20 grams of net carbs daily, as little as one serving of high-carb balsamic vinegar or balsamic glaze can push you out of ketosis.

Health benefits of balsamic vinegar

Most balsamic vinegar contains around six percent of acetic acid, an organic acid found in all types of vinegar and responsible for its acidic sharpness.

Research published in the Journal of Food Science suggests that acetic acid has potent antidiabetic, antiobesity, antimicrobial, and antioxidative properties and may support healthy blood pressure.

Compared to other types of vinegar, balsamic has the highest concentrations of resveratrol, a plant phytonutrient and antioxidant with profound benefits. 

A study published in Biomedicines concludes that resveratrol is linked to several health advantages, such as:

  • Improved blood sugar control

  • Weight loss

  • Anti-cancer effects

  • Skin health 

  • Strong immune defenses 

  • Digestive support  

  • Anti-aging effects
