For those following a ketogenic diet, the question of whether Guinness can be included is a common one. The short answer is "no," but the longer answer is "it depends". While most regular beers are not keto-friendly due to their high carbohydrate content, there are ways to enjoy alcohol in moderation while staying within the parameters of a keto or low-carb lifestyle.
Understanding the Keto Diet
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that shifts the body's primary energy source from carbohydrates to fats and protein. The classic ketogenic diet consists of 75% of total calories from fat, 20% from protein, and 5% from carbs. A person following an average 2,000-calorie diet would then limit his/her carbs to around 25 grams per day. This metabolic state, known as "ketosis," is when the body efficiently burns fats for fuel.
A more flexible approach, known as Mod Keto, allows for a higher carbohydrate intake, with a macronutrient distribution of 40-60% of calories from fat, 20-40% from protein, and 20% from carbs (up to 100 grams for a 2,000-calorie diet).
Beer and Carbohydrates: The Basics
Traditional beer is often high in carbohydrates. The average beer contains around 11 grams of carbohydrates per 12-ounce serving. For those adhering to a strict keto diet, this can quickly deplete their daily carbohydrate allowance.
What is Beer Made Of?
The malted grains are the primary source of calories and carbs in beer, providing the sugars that are fermented by yeast to produce alcohol and CO2 (natural carbonation). Malted barley is the most widely used grain in beer making, providing color, body, flavor, and aroma. Some brewers add unmalted grains and sugars to enhance flavor and drinkability.

Alcohol's Impact on the Body
When alcohol is consumed with carbohydrates, the body prioritizes detoxifying the alcohol in the liver. This process redirects energy sources and can halt gluconeogenesis (the production of glucose from non-carbohydrate sources), leading to the accumulation of lactate and the synthesis of fatty acids for storage.
Guinness and Its Carb Content
Guinness, despite its rich flavor and dark appearance, contains fewer carbs than one might expect. However, whether it fits into a keto diet depends on individual carb limits and overall daily intake.
Low-Carb Beer Options
Fortunately, there are low-carb beer options available that can be enjoyed in moderation on a keto diet. Some popular choices include:
- Bud Light Next: This beer boasts zero carbs and 80 calories.
- Miller Genuine Draft 64: With only 64 calories and 2.4 carbs.
- Miller Lite: A classic low-calorie and low-carb option.
- Busch Light: A lighter version of regular Busch with fewer calories and carbs.
- Blue Moon Light Sky: A light wheat beer with tangerine notes, containing 95 calories and less than four carbs.
Considerations for Drinking on Keto
Even with low-carb beer options, moderation is key. The calorie, carb, and alcohol content can still slow progress toward weight loss and ketosis if consumed excessively.
Alcohol Tolerance
It is important to note that alcohol tolerance may be lower on a low-carb or ketogenic diet. This is because when glycogen stores are depleted, alcohol is metabolized much faster.

Limiting the Damage
When consuming alcohol on keto, it is best to prioritize low-calorie and low-sugar beverages.
Alternative Alcoholic Beverages
If beer doesn't fit into your keto plan, there are other alcoholic beverages to consider:
- Pure Spirits: Tequila, rum, vodka, whiskey, and gin have zero carbs, but be cautious of flavored versions with added sugars.
- Dry Wine: Unsweetened champagne, dry red wine, and dry white wine are low in carbs.
- Low-Carb Cocktails: Mix traditional alcohol with zero-calorie beverages like diet soda or sugar-free lemonade.
Non-Beer Alternatives
For those seeking alternatives to beer, there are several options:
- Homemade Shandy: Mix low-carb beer with diet root beer or diet ginger beer.
- Low-Carb Alcoholic Seltzer Drinks: Truly Spike, White Claw, Spiked Seltzer, and Nauti Seltzer have less than 6 grams of net carbs per 12-ounce serving.
- Hard Liquor With Carbonated Water: Combine bourbon, scotch, or whiskey with carbonated water for a smoky and bitter flavor.
- Carbonated Water With Bitters and Extracts: Add hop-based bitters or hop liquid extract to carbonated water to mimic beer flavors.
- Kombucha: A fermented tea with probiotics, but be mindful of the sugar content.
- Low-Carb "Gluten-Free" Beer: Omission Ultimate Light has 5 grams of net carbs per 12 ounces.
The Importance of Moderation
Regardless of the chosen beverage, moderation is crucial. Men should limit themselves to no more than two drinks a day, while women should have no more than one.
Tracking Macros
Remember to track the calories and net carbs from alcoholic beverages and factor them into your daily macronutrient goals. Apps like MyFitnessPal or Cronometer can be helpful for this purpose.

The Impact of Alcohol on Fitness
Alcohol can hinder protein synthesis, which is necessary for muscle repair and growth, and it can also delay injury healing. It’s also been suggested that alcohol can diminish muscle-building pathways triggered by strength training.
Tips for Drinking Responsibly on Keto
- Eat Before and While Drinking: Food slows down alcohol absorption. Choose keto-friendly options like meat and vegetables.
- Stay Hydrated: Drink water before, during, and after drinking to offset dehydration.
- Pace Yourself: Avoid downing drinks quickly.
- Listen to Your Body: Pay attention to how different types and quantities of alcohol affect you.
- Drink a Few Hours Before Bed: This can minimize sleep disruption.
The Benefits of Moderate Alcohol Consumption
Numerous studies suggest that moderate alcohol consumption, particularly red wine, can have health benefits, such as helping with blood pressure, inflammation markers, and stress levels.
Getting Back on Track After Overindulging
If you happen to overindulge, drink plenty of water and go for a brisk walk to help your body recover.
