Is Beer Keto-Friendly?

Beer on a kitchen counter

Being on keto has never been about restricting food items. It's more about being mindful of macronutrients, mainly carbohydrates, and making choices that align with your dietary goals.

That said, can you drink beer on a keto diet? The plain answer is yes, you can, but it comes with a few catches!

The key to understanding this is to understand beer's carb content and how it fits into daily carb intake.

So dive in as we explore beer's carb content and discuss its benefits and nutritional value.


  • Yes, beer can be keto-friendly when consumed mindfully. One regular can of beer typically contains 12.64g of net carbs.
  • Beer can be creatively incorporated into your keto meal plan, and there are lower-carb alternatives worth exploring.

Is Beer Keto-Friendly?

Beer can be considered keto-friendly because it contains a moderate amount of net carbs, with around 12.64g per standard can (356g).

On the keto diet, keeping carb intake low is vital to enter ketosis, where the body burns fat for energy. Since a can of beer fits within the recommended daily carb limit of 20g to 50g for keto, it can be enjoyed, but in moderation.

Remember, you'll have to account for the carbs in other foods as well. So, be mindful of your overall carb intake for the day. This ensures you stay within your limits and maintain your progress towards your goals.

Can You Have Beer on a Strict Keto Diet?

While it's possible to include beer in a strict ketogenic diet, it can be challenging and isn't recommended due to its carb content. In this diet, where carb intake is limited to under 20g per day, fitting in beer, which typically contains around 12.64g of carbs per a standard can, can significantly impact your daily allowance.

However, there's also a broader spectrum of low-carb or modified keto diets, where people limit their daily carb intake to between 30 to 50g of net carbs. In these cases, beer can be enjoyed, as it better aligns with the higher carb limit while allowing room for other sources of carbs.

Carbs In Beer

When discussing the carbohydrate content in beer, it's essential to focus on net carbs. A single can of beer (356g) contains 12.64g of net carbs.

Additionally, beer has a high glycemic index of 70 [source]. The glycemic index is a value assigned to foods based on how slowly or quickly they cause increases in blood glucose levels. Foods low on the glycemic index (55 or less) are digested, absorbed, and metabolized slowly and cause a slower rise in blood glucose.

Those with a GI between 56 and 69 are considered medium, while those with a GI of 70 to 100 are considered high. Foods with a lower GI digest slowly, leading to a steady rise in blood sugar levels, whereas foods with a high GI are quickly digested, causing a rapid spike.

Beer Nutrition Facts

A single can of beer (356g) offers a varied nutritional profile. It contains 153 calories primarily from carbohydrates (12.64g), including a notable amount of alcohol sugars (13.9g). Beer also contains protein (1.64g).

On the micronutrient side, beer contains a suite of B-vitamins, such as riboflavin, niacin, and folate. It also provides minerals like potassium, magnesium, and phosphorus. An unexpected benefit is the presence of dietary fiber (0.75g), which is rare in beverage options.

Of particular note is beer's silicon content, which contributes to bone health. Furthermore, it's a source of polyphenols, plant compounds with antioxidant properties.

Incorporating Beer into Your Keto Meal Plan

  1. Portion Control: When incorporating beer into a keto meal plan, portion control is crucial. Remember that one can of beer contains 12.64g of net carbs, so limit the intake to fit the daily carb allowance.
  2. Counting Carbs: Keep track of all carbohydrate intake throughout the day. Use a carb tracking tool or app to ensure the consumption of beer along with other foods does not exceed the daily carb limit.
  3. Keto Recipes with Beer: Consider using beer as an ingredient in keto recipes. For example, it can be used in marinades for meats or in low-carb beer bread recipes. This way, beer can be enjoyed without disrupting the state of ketosis.

Keto-Compatible Alternatives for Beer

  1. Light Beers: Light beers are a good alternative to regular beer on a keto diet. They usually contain fewer carbs than regular beer, which can be helpful for those on stricter keto diets. For instance, some light beers have as little as 2-3g of carbs per 355ml serving.
  2. Hard Seltzers: Hard seltzers are another great alternative to beer. They are typically made from carbonated water, alcohol, and often a hint of fruit flavoring. With a carb content as low as 2g per can, they can easily fit into a keto diet. They can also be used as mixers in keto-friendly cocktails.
  3. Non-Alcoholic Beers: For those who enjoy the taste of beer but want to cut back on carbs and alcohol, non-alcoholic beers can be a good option. Many non-alcoholic beers contain fewer carbs than their alcoholic counterparts. However, it's important to check the nutritional information as the carb content can vary.
  4. Red Wine: Red wine can also serve as an alternative to beer on a keto diet. Dry red wines typically contain around 3-4g of carbs per 5-ounce serving. They can be enjoyed on their own or used in cooking, for example, in marinades or sauces for meat dishes.

Concluding Thoughts on Beer and Keto Keto Diet

Beer, with its 12.64g of net carbs per can, can be part of a keto diet if you're not following it too strictly.

When adding beer to your keto meal plan, it's crucial to be mindful. Watch your carb intake, control your portions, and enjoy beer in moderation.

While beer can fit into a keto lifestyle, there are also other options to consider, like light beers, hard seltzers, non-alcoholic beers, and dry red wines. You could even have a fun "beer tasting" night to try out different low-carb options and hard seltzers, making your keto journey more exciting!

Cast Iron Keto's Editorial and Research Standards

Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.

First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.

When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).

Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.

Frequently Asked Questions

A standard 12-ounce can of beer typically contains around 12.64g of net carbs.

Absolutely! Beer can be used in various keto recipes, such as marinades for meat or in low-carb beer bread recipes.

Not all beers are created equal. Light beers, for example, usually contain fewer carbs than regular beer. Non-alcoholic beers also often contain fewer carbs, but it's essential to check the nutritional information as the carb content can vary.

Moderation is key. While beer can fit into the daily carb allowance, frequent consumption might take up a significant portion of your carb limit, leaving little room for nutrient-dense foods.
