Is beer keto?

When it comes to following a ketogenic diet, one of the most common questions that arises is whether or not beer is keto-friendly. The ketogenic 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. Since beer is typically associated with carbohydrates, it is important to understand how it fits into a keto lifestyle.

The carbohydrate content of beer

Beer is made from grains such as barley, wheat, and corn, which are high in carbohydrates. These carbohydrates are converted into sugar during the brewing process, which is then fermented by yeast to produce alcohol. As a result, most beers contain a significant amount of carbohydrates.

Here are some examples of the carbohydrate content in popular beer varieties:

  • A regular 12-ounce (355 ml) can of beer typically contains around 12-15 grams of carbohydrates.
  • A light beer, on the other hand, usually contains around 3-6 grams of carbohydrates per 12-ounce (355 ml) serving.
  • Craft beers and specialty beers can have even higher carbohydrate content, ranging from 15-30 grams or more per serving.

Impact on ketosis

Consuming carbohydrates can disrupt ketosis, as the body will prioritize burning the carbohydrates for energy instead of fat. This can make it challenging to maintain a state of ketosis while enjoying beer.

However, it is important to note that everyone’s tolerance to carbohydrates varies, and some individuals may be able to consume small amounts of beer without being kicked out of ketosis. Factors such as activity level, metabolism, and overall carbohydrate intake throughout the day can influence how beer affects ketosis.

Low-carb beer options

For those who still want to enjoy beer while following a ketogenic diet, there are low-carb beer options available. These beers are specifically designed to have a reduced carbohydrate content, making them more compatible with a keto lifestyle.

Some examples of low-carb beer options include:

  • Michelob Ultra: This light beer contains only 2.6 grams of carbohydrates per 12-ounce (355 ml) serving.
  • Budweiser Select 55: With just 1.9 grams of carbohydrates per 12-ounce (355 ml) serving, this beer is one of the lowest in carbs.
  • Corona Premier: This light beer contains 2.6 grams of carbohydrates per 12-ounce (355 ml) serving.

Alternatives to beer

If you are following a strict ketogenic diet and want to avoid the potential impact of beer on ketosis, there are alternative options available that can still provide a similar experience.

Some alternatives to beer that are more keto-friendly include:

  • Hard seltzers: These alcoholic beverages are typically made with carbonated water and a hint of flavor. They are often low in carbohydrates and calories, making them a popular choice for those following a keto diet.
  • Spirits: Spirits such as vodka, gin, and tequila are generally low in carbohydrates and can be enjoyed with sugar-free mixers.
  • Wine: Dry wines, such as red or white wine, tend to have lower carbohydrate content compared to sweeter varieties.


While beer is not typically considered keto-friendly due to its carbohydrate content, there are low-carb beer options available for those who still want to enjoy a cold one while following a ketogenic diet. It is important to be mindful of the carbohydrate content in beer and how it may impact ketosis. Ultimately, the decision to include beer in a keto lifestyle should be based on individual tolerance and goals.
