Alcohol And Keto: Friends Or Foes?

Alcohol and the keto diet is a hot topic. Many people want to know if they can still enjoy a drink while trying to lose weight. The short answer is: yes and no. While alcohol doesn't contain any carbs and won't kick you out of ketosis, it does have a lot of empty calories and can slow down the fat-burning process, potentially hindering your weight loss goals.

On the keto diet, your body uses fat for energy instead of carbs. When you drink alcohol, your liver focuses on metabolising it instead of burning fat. This slows down the production of ketones, which are energy molecules created when the liver turns fat into energy.

Additionally, alcohol can lower your inhibitions and willpower, making it harder to stick to your diet and potentially leading to poor food choices. It's also important to note that alcohol can affect people differently, so while one drink may not affect someone else, it could have a more significant impact on you.

So, while the occasional drink on the keto diet may not completely derail your progress, frequent drinking or high-carb beverages can stall your weight loss. It's essential to be mindful of your consumption and how it affects your body.

Alcohol is metabolised differently on keto

Alcohol has around 7 calories per gram, so it is sometimes classified as the fourth macronutrient. However, unlike carbohydrates, fats and protein, it is not essential. You don't need it to survive.

When you're on a keto diet, your body will metabolise alcohol faster, which leads to a lower alcohol tolerance. This means you will feel the effects of alcohol more quickly and may be caught off guard.

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. Overall, even if the alcohol consumed is not high in carbohydrates, it does provide energy for the body to burn rather than fat, essentially slowing the ketosis process.

Alcohol slows fat-burning

Alcohol is often classified as the fourth macronutrient as it contains about seven calories per gram. However, unlike the other three macronutrients (carbohydrates, fats, and proteins), alcohol is not essential for survival. On a keto diet, the body uses fat for energy instead of carbs. In the absence of carbs, the liver turns fat into energy molecules called ketones. When you drink alcohol, your body starts to metabolise it, breaking it down into acetate, which your body can use for energy. Until all the alcohol has been processed, your body won't produce ketones from fat. This is what slows down the fat-burning process.

The impact of alcohol on fat-burning also depends on the type of alcoholic beverage. Sweet mixed drinks and beer are full of sugar and carbs that can immediately bring you out of ketosis. Straight liquor and dry wine can also cause issues for some people. Even if you drink a low-carb alcoholic drink, your body may react differently from someone else's.

Additionally, alcohol can affect your willpower and inhibitions, making it easier to give in to cravings for unhealthy foods, which can also hinder your weight loss efforts.

Alcohol affects tolerance

When a person is in ketosis, their body will metabolise alcohol to deal with it as a toxin, and this takes priority over metabolising other substances. This means that the breakdown of fat is paused while the body processes the alcohol. As a result, people in ketosis will feel the effects of alcohol more quickly and may experience worse hangovers.

The keto diet lowers alcohol tolerance due to low glycogen levels. Carbohydrates can reduce blood alcohol levels, but in ketosis, there is an absence of carbohydrates and other sources of energy, so alcohol reaches the bloodstream quicker and is processed more quickly. This reduces tolerance to alcohol.

It is important to note that alcohol can also affect willpower, making it harder to stick to a keto diet. Additionally, alcohol provides extra calories and can slow down weight loss. Therefore, while it is possible to drink alcohol and remain in ketosis, it may be wise to limit alcohol consumption or avoid it altogether to maximise the benefits of the keto diet.

Alcohol affects willpower

Alcohol can affect willpower in several ways. Firstly, it can reduce self-awareness and lower inhibitions, making it easier to give in to impulses or cravings. This is especially true for those with a history of addictive behaviours or a lack of control over their eating or drinking habits. In these cases, alcohol can act as a trigger, leading to a loss of willpower and a return to unhealthy patterns.

Secondly, alcohol interferes with the body's ability to burn fat by disrupting the production of ketones, which are energy molecules derived from fat. This can slow down weight loss and derail fitness goals, requiring willpower to counteract.

Additionally, alcohol can affect decision-making abilities, particularly in individuals with alcoholism. It impairs executive functions and cognitive control mechanisms, such as response inhibition and shifting attention. This can result in disinhibited behaviour and a decreased ability to make choices aligned with long-term goals.

Finally, alcohol can impact willpower by altering glucose metabolism and reducing blood glucose levels. This can lead to decreased self-control and an increased likelihood of engaging in impulsive behaviours.

Alcohol is not a health food

On the keto diet, the body uses fat for energy instead of carbohydrates. When alcohol is consumed, the liver prioritises metabolising it, temporarily halting ketosis and slowing down the fat-burning process. This can ultimately slow down weight loss. Additionally, alcohol is broken down into acetate, which the body uses for energy instead of fat. Therefore, even if the alcohol consumed is not high in carbohydrates, it still provides an alternative energy source for the body, slowing down the ketosis process.

Alcohol also affects the body's tolerance. Carbohydrates help manage the tipsy feeling by slowing down the metabolisation of alcohol and reducing blood alcohol levels. However, when following a ketogenic diet, the body has very few carbohydrates, causing alcohol to be processed faster and leading to a quicker onset of intoxication. This reduced alcohol tolerance can be dangerous and should not be taken lightly.

Furthermore, alcohol weakens inhibitions and willpower, making it easier to give in to cravings for unhealthy foods that can throw you out of ketosis. It is important to be mindful of these potential consequences and make informed choices when consuming alcohol while on the keto diet.

While alcohol may not completely kick you out of ketosis, it can stall your progress. If you are focused on weight loss, it is best to minimise alcohol consumption or avoid it altogether until you reach your goals.
