The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where fat reserves are broken down into chemicals called ketones, which are then used for energy. While it is possible to drink alcohol and remain in ketosis, the body may prioritise breaking down alcohol over ketones, potentially slowing weight loss. Alcoholic drinks with lower carb content, such as pure spirits, wine, and light beer, are considered more keto-friendly than those with higher carb content, like beer and cocktails.

What You'll Learn
Pure alcohol has zero carbs
While pure alcohol has zero carbs, it is essential to consider the impact of alcohol on the body and overall health. Alcohol is an energy source with almost no nutritional value, and the body prioritizes processing it over burning other sources of energy, such as body fat. This can slow down weight loss and affect health gains on a low-carb diet. Additionally, alcohol stimulates appetite and decreases inhibitions, leading to increased food intake. Therefore, while pure alcohol may have zero carbs, excessive consumption can still impact overall health and weight management.
When it comes to alcoholic beverages, wine and light beer are relatively low in carbs, usually containing under 6 grams per serving. Champagne and dry wines, for example, have around 2 grams of carbs per serving, while a typical beer has 13 grams. However, it is important to note that the carb content can vary depending on the brand and type of beer.
It is worth mentioning that while pure alcohol has zero carbs, the impact of alcohol on ketosis and the keto diet is complex. Alcohol is treated as a toxin by the body, and the liver will prioritize processing it over other nutrients. This can slow down the process of converting fatty acids to ketones, affecting ketosis. Additionally, drinking alcohol may make it more challenging to resist non-keto temptations, as it lowers inhibitions and increases the likelihood of overeating unhealthy foods. Therefore, while pure alcohol has zero carbs, drinking it while on a keto diet may impact an individual's progress and goals.
In conclusion, pure alcohol, such as whiskey, vodka, gin, and tequila, has zero carbs. However, it is important to consider the impact of alcohol on the body, weight management, and specific diets like keto. While pure alcohol may fit within the carb restrictions of a low-carb diet, moderation is crucial to maintaining overall health and avoiding adverse effects.

Wine and light beer are lower in carbs
Light beers typically have 145 calories in a 12-ounce serving, while low-carb beers start at around 95 calories per bottle. A bottle of wine will have fewer calories than a bottle of beer, but beers usually come in smaller, single-serving bottles or cans.
When it comes to carbs, wine and light beer typically contain under 6 grams per serving. Pure forms of alcohol like whiskey, gin, tequila, rum, and vodka are all completely free of carbs.
If you're on a keto diet, wine is a more keto-friendly option than beer due to its lower carb content. However, drinking alcohol while on a keto diet can impact your progress by slowing down your rate of ketosis. It can also make your hangovers worse and increase your risk of nutritional deficiencies and weight gain over time.
In terms of weight loss, it's important to consider not just the calories in the drink but also the impact on your overall diet and exercise habits. Heavy drinking has been linked to higher rates of obesity, and it can be challenging to stick to a healthy diet and exercise routine after consuming alcohol.

Alcohol affects ketosis by slowing down the rate of ketosis
Alcohol can affect ketosis by slowing down the rate at which the body enters this state. This is because the liver focuses on metabolizing alcohol instead of fat. Until all the alcohol has been processed by the liver, the body will not produce ketones from fat, thus slowing down the fat-burning process.
Ketosis is a metabolic state in which the body burns fat instead of carbohydrates for energy. The liver converts stored fat into ketones, which are usable forms of energy. Alcohol, however, interrupts this process. While alcohol is not stored in the body like carbohydrates, protein, or fat, it can still be used for energy. The liver will prioritize processing alcohol over fat, which slows down the production of ketones.
The type of alcohol consumed also matters. Many alcoholic beverages, such as beer, certain wines, and cocktails, are loaded with carbohydrates. Consuming these drinks will cause the body to exit the state of ketosis since carbohydrates are present to metabolize. However, some types of alcohol are low in carbohydrates, such as clear liquors like vodka, gin, or tequila, and some dark liquors like rum, cognac, or scotch. These drinks may not provide carbohydrates for the body to burn, but the body can still turn alcohol into usable energy.
Even if a low-carb alcoholic drink is consumed, it is important to consider how the body processes alcohol. Alcohol has about 7 calories per gram and is sometimes classified as a macronutrient. On a ketogenic diet, the body uses fat for energy instead of carbohydrates. When alcohol is consumed, the liver focuses on metabolizing it, and the production of ketones from fat is slowed or halted. This can potentially slow down weight loss goals for those on a ketogenic diet.
Additionally, alcohol can affect ketosis by lowering alcohol tolerance. Carbohydrates can reduce blood alcohol levels, but during ketosis, there is an absence of carbohydrates and other sources of energy. As a result, alcohol reaches the bloodstream quicker and is processed more quickly, leading to a reduced tolerance. This means that even a small amount of alcohol can affect ketosis by slowing down the rate at which the body enters this state.

Alcohol can increase the risk of nutritional deficiencies and weight gain
It is important to note that while alcohol does not stop ketosis, it does impact it. Drinking alcohol while on a keto diet will slow down your rate of ketosis. This is because the liver treats ethanol as a toxin and will work to get rid of it as soon as possible, which slows down the process of converting fatty acids to ketones.
In an eight-year study involving 49,324 women, consuming at least two drinks per day was associated with an increased risk of significant weight gain compared to light or moderate drinking. Alcohol can also suppress fat burning and increase body fat by causing the body to store extra calories as fat tissue.
Additionally, alcohol can affect the body's ability to absorb some nutrients, such as folate, a vitamin that cells need to stay healthy. Alcohol may also raise estrogen levels in the body, which could increase the risk of breast cancer.
It is important to moderate alcohol intake to avoid adverse health effects. Even low-carb varieties of alcohol can contribute to weight gain, nutritional deficiencies, and serious health conditions.

Alcohol can affect decision-making and willpower, which may cause someone to break their diet
Alcoholism is a form of addiction characterised by an imbalance between two separate but interacting psychological registers leading to a loss of willpower. The first is an impulsive/reactive register for signalling immediate prospects, and the second is a reflective/effortful register needed to moderate the response triggered by the impulsive system.
Alcohol can acquire properties of triggering bottom-up, unintentional signals that modulate and bias top-down, goal-driven attentional resources needed for the normal operation of the reflective system and for exercising willpower. In other words, the more alcohol one consumes, the more their willpower is affected.
Alcohol can also affect decision-making. Alcoholism is paradigmatic of impaired decision-making under ambiguity. Compared to normal controls, a high proportion of participants detoxified and abstinent for a few weeks or even several years performed poorly on the Iowa Gambling Task (IGT), making choices that bring immediate reward but lead to more severe delayed punishment.
Alcohol can also affect people's ability to resist non-keto temptations. Alcohol lowers social inhibitions, and having a few glasses of wine might make someone less able to resist the siren call of late-night French fries. "You'll be more likely to overeat unhealthy foods since your inhibitions are lowered," said Dr Anthony Gustin on Perfect Keto.
