Alcohol And Keto: What You Need To Know

Alcohol is known for being high in carbs, but it is possible to drink alcohol in moderation and remain in ketosis. Alcoholic drinks with low carbs include pure spirits like gin, whiskey, vodka, and tequila, which contain zero carbs and sugars. Dry red or white wines are also keto-friendly, with around 1 gram or less of sugar per ounce. Light beers are also an option, with some containing only 2-3 grams of carbs. However, it's important to note that alcohol can slow down the fat-burning process and weight loss, and it can also lead to lowered alcohol tolerance and worse hangovers.

Alcohol can slow down weight loss

Alcohol is not essential to the body and is often referred to as empty calories. It is possible to drink alcohol and remain in ketosis, but it will slow down the fat-burning process and, in turn, your weight loss goals.

When you are on a keto diet, your body uses fat for energy instead of carbohydrates. In the absence of carbohydrates, the liver turns fat into energy molecules called ketones. When you drink alcohol, your body begins to metabolise it, which means it breaks it down. The liver focuses its attention on metabolising the alcohol instead of fat. Until all the alcohol has been processed, your body will not produce ketones from fat. This slows down the fat-burning process.

Alcohol is also 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.

Alcohol can also lead to weight gain in the long term. 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.

Pure spirits have zero carbs

Pure spirits such as whiskey, gin, tequila, rum, cognac, and vodka contain no carbs and are suitable for a keto diet. However, it is important to be cautious of what you mix them with, as many popular mixers will turn your drink into a high-carb disaster. Soft fizzy drinks, energy drinks, and fruit juices are loaded with carbs, so they should be avoided if you are following a low-carb diet.

If you are craving something sweet, you can try keto-friendly mixers like soda water, flavoured sparkling water, or bitters, which contain as little as 2 grams of carbs per half teaspoon. While diet soda is also an option, many people on keto choose to avoid artificial sweeteners.

If you are drinking alcohol on a keto diet, it is important to keep in mind that it can slow down your weight loss progress. Alcohol is an energy source with almost no nutritional value that your body prioritises burning over other sources of energy, such as body fat. Additionally, alcohol can further impede weight loss by stimulating appetite and decreasing inhibitions, leading to increased food intake.

It is also worth noting that when on a keto diet, you might feel stronger effects from alcohol, including intoxication and hangovers. This is because a keto diet can lead to a lower alcohol tolerance, and your body may process alcohol faster. As a result, you might find that drinking alcohol on a keto diet leads to worse hangovers.

Wine is lower in carbs than beer

When it comes to alcoholic drinks, it can be tricky to know how to maintain a healthy lifestyle and still indulge. Alcohol is known for being high in carbs, but some choices contain far more than others.

Wine vs Beer Calories

Firstly, it's important to note that the calories in wine vs beer vary only slightly. Beer, which is made using grains and yeast, varies in calories based on the type you drink. Most light beers have between 60 and 120 calories, while dark beers, which are a bit heavier and tend to have more carbohydrates, have between 100 and 300 calories. The calories in wine, on the other hand, range from 120 to 210 calories per six-ounce glass. Red wine is made by including grape skin in the fermentation process, while white wine does not, resulting in its lighter colour.

Carbohydrates in Wine and Beer

When it comes to carbohydrates, wine has a lower carb count than beer. Beer typically contains about 12.6 grams of carbohydrates per can, while a standard 5-ounce glass of wine contains just 1 or 2 grams of carbohydrates. A 12-ounce serving of a 5% alcohol beer has between 10 and 20 grams of carbs, or 40 to 80 extra calories. So, if you're looking to cut down on your carb intake, beer may not be the best choice.

Nutritional Differences

Beer and wine also have distinct differences in ingredients and nutritional value. Beer has more selenium, B vitamins, phosphorus, folate and niacin than wine. Beer also has significant protein and some fibre. Wine, on the other hand, tends to have a relatively low sugar content.

Alcohol Content

Wine contains more than double the amount of alcohol in beer, so you'll typically drink less of it. However, this doesn't mean the calorie count is much different. One standard drink is defined as 12 ounces of 5% ABV beer or five ounces of 12% ABV wine.

Weight Loss

When it comes to weight loss, neither wine nor beer is smart to drink in excess. While wine has a lower carb count, it sometimes makes up for that in sugar content. Alcoholic drinks can hinder your weight loss goals when consumed in large amounts, as they provide non-essential or "empty" calories.

Keto-Friendly Options

If you're following a ketogenic diet, you can still drink alcohol, but there are certain drinks you might want to avoid to stay in ketosis. Wine is a more keto-friendly option than beer because of its lower carb content. Pure spirits like whiskey and vodka contain zero carbs, so these are also good choices.

Alcohol interrupts the ketosis state

Alcohol does indeed interrupt the ketosis state, even if it has no carbs. This is because the liver prioritises the detoxification of ethanol (pure alcohol) over other metabolic functions, which inhibits fat-burning and ketosis.

When you are in ketosis, your body uses fat for energy instead of carbohydrates. In the absence of carbs, the liver turns fat into energy molecules called ketones. However, when you drink alcohol, your body begins to metabolise it instead of fat. Until all the alcohol has been processed, your body won't produce ketones from fat. This slows down the fat-burning process and can slow down weight loss.

Alcohol is also a toxin, and when consumed, the liver will start to process it as quickly as possible. This means alcohol is used by the body before all other nutrients, including fat, which slows the process of converting fatty acids to ketones.

In addition, alcohol can trigger powerful carb and sugar cravings while impairing judgment and self-control, which may lead to overeating carb-rich meals and exceeding your daily net carb count.

It typically takes between 48 and 72 hours to restart ketosis after consuming alcohol, depending on how much alcohol you drink and how quickly your liver detoxifies ethanol.

Alcohol tolerance is lowered on a keto diet

Alcohol tolerance is indeed lowered on a keto diet. This is due to the fact that the keto diet is a low-carb, high-fat diet. When the body is in ketosis, it burns fat for fuel instead of carbohydrates. This means that the liver converts stored fat into ketones, which are usable forms of energy.

On a keto diet, the body's glycogen levels are very low. Glycogen is a substance that helps to absorb alcohol in the body. With low levels of glycogen, there are fewer substances in the body to absorb alcohol. As a result, alcohol reaches the bloodstream quicker and is processed more quickly, leading to reduced alcohol tolerance.

In addition, alcohol is broken down by the liver and provides energy for the body to burn. When a person is in ketosis, the liver prioritises metabolising alcohol over fat, which slows down the fat-burning process. This further contributes to the lowered alcohol tolerance experienced on a keto diet.

The reduced alcohol tolerance on a keto diet can be a surprise to some, and it is important to be mindful of how alcohol affects the body in this state. It is recommended to take a cautious approach and be aware of the potential for impairment, especially when driving.

Furthermore, drinking alcohol on a keto diet can lead to worse hangovers. This may be due to dehydration and electrolyte imbalances caused by the diuretic effect of alcohol, which can be more pronounced when the body is already in a state of increased fluid loss due to the nature of the keto diet.

In summary, alcohol tolerance is lowered on a keto diet due to decreased glycogen levels and the liver's prioritisation of metabolising alcohol over fat. This can lead to unexpected effects of alcohol and worse hangovers. It is important to be cautious and aware of how alcohol affects the body when in ketosis.
