The ketogenic diet is a popular low-carb, high-fat diet that aims to induce a state of ketosis in the body. Ketosis is a metabolic process that occurs when the body does not have enough carbohydrates to burn, so it burns fat instead. Alcohol does not stop ketosis, but it does impact it. It is possible to drink alcohol and maintain a ketogenic diet, but it is important to understand how the two interact. Alcohol is unique in that it cannot be stored in the body like carbohydrates, protein, or fat. When alcohol is consumed during ketosis, the body will convert to using it as an energy source rather than fat, which slows down the fat-burning process and can impact weight loss goals.
Characteristics | Values |
---|---|
Can you drink alcohol on keto? | Yes, but it will impact ketosis. |
Will drinking kick you out of ketosis? | One or two drinks shouldn't affect ketosis, but more than that probably will. |
Best alcoholic drinks to have on keto | Pure spirits like whiskey, vodka, gin, and tequila contain zero carbs. Dry wines are also a good option. |
Alcoholic drinks to avoid on keto | Beer, cocktails, and sweet wines are high in carbs and should be avoided. |
Effect of alcohol on weight loss | Alcohol interrupts the ketosis state and adds extra calories to the diet. However, if a caloric deficit is maintained, even after consuming alcohol, weight loss will occur. |
Effect of keto on alcohol tolerance | The keto diet lowers alcohol tolerance due to low glycogen levels. |
Effect of alcohol on willpower | Alcohol can lower inhibitions and willpower, making it difficult to resist non-keto temptations. |
What You'll Learn
Alcohol is a toxin to the body and will slow down the fat-burning process
When you drink alcohol, your body metabolises it, breaking it down into a sugar called acetate, which is then used for energy. This means that while you are in the process of metabolising alcohol, your body puts fat burning on hold.
Alcohol is unique in that it cannot be stored in the body like carbohydrates, protein or fat. Because alcohol cannot be stored, it interrupts the metabolism of other types of calories until it is broken down. When in ketosis, alcohol halts the metabolism of fat to metabolise alcohol.
The liver will start to process alcohol as quickly as possible, which means it is used by the body before all other nutrients, including fat. This slows down the process of converting fatty acids to ketones.
The bottom line is that if you are a very occasional drinker, alcohol probably won't derail your keto lifestyle. But if you find yourself drinking high-carb beverages, or drinking often, you might be slowing down the fat-burning process.
If you are following a keto diet, there are some alcoholic drinks you might want to avoid if you want to stay in ketosis. Wine is more keto-friendly than beer because of its lower carb content. Pure spirits like whiskey and vodka contain zero carbs, but watch out for sweet drinks – they may contain massive amounts of sugar.

Alcohol is high in calories and can affect weight loss
Alcohol can also affect your willpower, making it harder to stick to your keto diet. It's also important to remember that the body may use energy from alcohol before using ketones from body fat, which could potentially limit the effect of the diet.
If you're on the keto diet, it's best to opt for lower-calorie alcoholic drinks, such as pure spirits like whiskey and vodka, which contain zero carbs. Wine is also a relatively keto-friendly option, with around 4 grams of carbs per glass.

Alcohol affects the body's ability to produce ketones
Alcohol can affect the body's ability to produce ketones. Ketosis is a metabolic state in which the body uses ketones, which are chemicals produced by the liver from fat reserves, as its main source of energy instead of carbohydrates. Alcohol provides an alternative source of energy, which the body will prioritise over ketones. This means that the body will temporarily halt the process of burning fat to metabolise alcohol.
When alcohol is consumed, the liver breaks it down into a sugar called acetate. The body then uses this for energy, putting fat burning on hold. Alcohol is unique in that it cannot be stored in the body like carbohydrates, protein or fat. This means that when alcohol is present in the body, the metabolism of other types of calories is interrupted until the alcohol is broken down.
The body can still enter a state of ketosis if the caloric deficit is maintained, even after consuming alcohol. However, alcohol does slow down the process of ketosis. It is important to note that people following a keto diet to treat a medical condition, such as diabetes or epilepsy, should avoid alcohol.

Alcohol can increase the rate of ketosis
The liver breaks down alcohol into a sugar called acetate, which is then used by the body for energy. This means that fat burning is put on hold.
However, alcohol is converted into ketones by the liver, and these ketones can be used as energy by the body. Therefore, alcohol consumption can lead to a surplus of ketones, which is the goal of the ketogenic diet.
It is important to note that alcohol can negatively affect decision-making, and may cause someone to break their diet. Additionally, alcohol is toxic to liver cells and can have detrimental effects on motor function. Therefore, while alcohol may increase the rate of ketosis, it is not a healthy option and should be consumed in moderation.

Alcohol affects the body's ability to process other nutrients
Alcohol is unique in that it cannot be stored like carbohydrates, protein, or fat. Because alcohol can't be stored, it essentially halts the metabolism of other types of calories until it is broken down. When in ketosis, alcohol halts the metabolism of fat to metabolize alcohol.
The liver will start to process alcohol as quickly as possible, which means it is used by the body before all other nutrients, including fat. This slows down the process of converting fatty acids to ketones.
Additionally, alcohol is broken down by several enzymes into acetate, which the body uses for energy. When alcohol is consumed during ketosis, the body will convert to using acetate as an energy source rather than fat. This means that even if the alcohol consumed is not high in carbs, it provides energy for the body to burn rather than fat, essentially slowing down the ketosis process.
It's important to note that the amount and frequency of alcohol consumption will impact how it affects your body. Heavy drinking can have serious long-term effects, such as a shortened attention span. Binge drinking can also lead to alcohol poisoning and even death. Therefore, it's crucial to practice responsible drinking and moderation, which is generally defined as up to two drinks per day for men and one drink per day for women.

Frequently asked questions
Yes, you can drink alcohol on a keto diet, but it will impact your progress. Alcohol is treated as a toxin by your body and will be prioritised over other nutrients, including fat, which slows the process of converting fatty acids to ketones.
The best alcoholic drinks to consume on a keto diet are pure spirits such as whiskey, vodka, gin, and rum, which contain zero carbs. Dry red or white wines are also a good option, with around 4.7g of carbs per standard glass.
You should avoid beer and cocktails, which are loaded with carbohydrates and can take the body out of ketosis. You should also avoid sweet drinks, which may contain massive amounts of sugar.
Drinking alcohol can make you feel tipsy or drunk much quicker, as there are very low levels of glycogen in your body to absorb the alcohol. Alcohol can also affect your willpower, making it harder to resist non-keto temptations.
