Whiskey is a keto-approved drink. It is a zero-carb option, but it still contains calories and will slow down weight loss. It is best to consume whiskey in moderation, as excessive drinking may lead to weight gain and adverse health effects.

What You'll Learn
Pure alcohol has zero carbs
Liquor is usually the best choice when sticking to a keto diet. Even though hard liquor is made from natural sugars, grains, potatoes, and fruits, during the fermentation and distillation process, that sugar is converted into ethyl alcohol.
Drinking liquor can, in fact, deepen your level of ketosis, but it will slow weight loss down. Ingestion of alcohol has effects on liver metabolism, in which more ketones are produced as you drink more. When your liver is taking care of the alcohol you drink, it’s being converted to a triglyceride, which can also positively affect the production of ketones.
It's important to note that drinking alcohol while on a keto diet can have some negative effects. Firstly, alcohol is burned as a priority by the body, slowing down fat loss. Secondly, most people on a keto diet experience a much lower tolerance to alcohol. Finally, alcohol can increase hunger and cravings for high-carb foods, leading to bad decisions and overconsumption.

Alcohol is metabolised differently on keto
The liver of a person on a high-carbohydrate diet has a lot of glycogen stored. If you're eating a carbohydrate-rich diet, the pathways for fat burning are busy breaking down sugars, and the alcohol is metabolised slower because of this hold-up. Conversely, a person on a low-carb diet has depleted their liver's glycogen stores and is now running on fats instead of carbs and glucose, burning body fat more efficiently. Since their glycogen stores are low, the alcohol ingested will start to be metabolised by the liver right away.
This immediate metabolisation will cause a sudden onset of a drunk feeling. Your liver isn't going to warn you when that alcohol has arrived for processing. Many people on keto experience a lowered tolerance because their liver is ready to metabolise efficiently instead of feeling sluggish processing extra carbs and sugars.
Alcohol has about 7 calories per gram, so it's sometimes classified as the fourth macronutrient. But unlike carbs, fats and protein, it's not essential. You don't need it to survive. On the keto diet, your body treats alcohol as a toxic substance. When it enters your bloodstream, your body shifts gears and focuses all of its energy on processing the alcohol out of your system.

Alcohol tolerance is lower on keto
When you're on a keto diet, you'll find that your alcohol tolerance is significantly lower than usual. This means that you'll get drunk faster and experience worse hangovers.
When you're on a keto diet, your body enters a state called ketosis, where it burns stored fats as fuel instead of carbohydrates. This happens because you're restricting your carb intake, which depletes your body's glycogen stores. Glycogen is a substance that's capable of absorbing alcohol, so when you're on a keto diet, there's less glycogen in your bloodstream to slow down the rate at which you get drunk.
Additionally, when you're in ketosis, alcohol is rapidly sent to your liver and converted into a substance called acetaldehyde, which is then metabolized faster. This process is what makes you feel intoxicated.
- Don't drink on an empty stomach. Eat a meal with lots of low-carb fruits and vegetables before drinking.
- Avoid beer and sugary drinks, which are packed with carbs. Stick to hard liquor or dry wines that are not very sweet.
- Stay hydrated by alternating water with alcohol. Aim for one glass of water per drink.
- Slow down your drinking. Try to have only about one drink per hour if possible.

Alcohol is calorific
Alcohol is the fourth macronutrient, providing our body with energy. However, these are empty calories as alcohol does not provide our body with any nutrients, vitamins or minerals.
When drinking alcohol, it is easy to consume a meal's worth of calories without realising. For example, a standard glass of wine can contain up to 158 calories, and some pints of stronger lager can contain up to 222 calories.
On the ketogenic diet, it is recommended to opt for pure distilled alcohol, which contains zero carbs. Dry wines and champagnes/sparkling wines are also strong choices, although most of them do have some carbs.

Alcohol is burned as a priority by the body
Alcohol still counts as calories and will slow fat loss down. Alcohol is burned as a priority by the body. The body treats alcohol as a toxic substance. When it enters your bloodstream, your body shifts gears and focuses all of its energy on processing the alcohol out of your system. Everything else hits the pause button to take care of the alcohol, including digesting the high-carb foods you may have eaten in preparation.
Alcohol is often "empty" calories
Alcoholic drinks are often referred to as "empty" calories. This means that they provide your body with calories but contain very little nutrients. There are almost 155 calories in one 12-ounce can of beer, and 125 calories in a 5-ounce glass of red wine. By comparison, a recommended afternoon snack should have between 150 and 200 calories. A night out with several drinks can lead to consuming a few hundred extra calories.
Alcohol affects your organs
The primary role of your liver is to act as the “filter” for any foreign substances that enter your body, such as drugs and alcohol. The liver also plays a role in the metabolism of fats, carbohydrates, and proteins. Excess alcohol consumption can lead to what is known as alcoholic fatty liver. This condition can damage your liver, affecting the way your body metabolizes and stores carbohydrates and fats. Changes in the way your body stores energy from food can make it very difficult to lose weight.
Alcohol affects judgment calls, especially with food
Even the most die-hard diet fan will have a hard time fighting the urge to dig in when intoxicated. Alcohol lowers inhibitions and can lead to poor decision-making in the heat of the moment — especially when it comes to food choices. animal study found that mice given ethanol over a period of three days demonstrated a significant increase in food intake. This study suggests that alcohol can actually trigger hunger signals in the brain, leading to an increased urge to eat more food.
Alcohol affects digestion and nutrient uptake
Intake of alcoholic beverages can also inhibit proper digestive function. Alcohol can cause stress on the stomach and the intestines. This leads to decreased digestive secretions and movement of food through the tract. Digestive secretions are an essential element of healthy digestion. They break down food into the basic macro- and micronutrients that are absorbed and used by the body. Alcohol intake of all levels can lead to impaired digestion and absorption of these nutrients. This can greatly affect the metabolism of organs that play a role in weight management.
