Alcohol is often referred to as 'empty calories', providing your body with calories but very few nutrients. A 12-ounce can of beer contains around 155 calories, and a 5-ounce glass of red wine contains around 125 calories. As such, drinking beer can hinder weight loss. When alcohol is consumed, it is burned by the body as a fuel source before anything else, including glucose from carbohydrates or lipids from fats. This means that excess glucose and lipids are stored as fat. Alcohol can also affect your organs, particularly the liver, which plays a role in metabolising fats, carbohydrates, and proteins. Excess alcohol consumption can lead to alcoholic fatty liver, which can damage the liver and affect the way the body metabolises and stores energy from food.
What You'll Learn
Beer is high in calories
The high-calorie content of beer means that drinking it regularly can contribute to weight gain. This is especially true when beer is consumed alongside high-calorie mixers, such as fruit juice or soda, or fatty foods. The excess calories from these drinks and foods are stored as fat in the body, leading to weight gain.
In addition, alcohol interferes with the body's fat-burning mechanisms. When alcohol is consumed, the body prioritises burning it as a fuel source before using glucose from carbohydrates or lipids from fats. This means that the excess glucose and lipids are stored as adipose tissue, or fat.
The high-calorie content of beer, combined with its impact on the body's metabolism, makes it a significant contributor to weight gain. As such, reducing beer consumption or opting for lower-calorie alcoholic beverages can be beneficial for individuals trying to lose weight.

Alcohol is metabolised as a priority over other nutrients
Alcohol is high in calories and can hinder weight loss. When consumed, alcohol is burned first as a fuel source before the body uses anything else, such as glucose from carbohydrates or lipids from fats. This means that excess glucose and lipids are stored as fat.
Alcohol is treated by the body as a poison. When alcohol is ingested, the body shuts down all other metabolic pathways to focus on metabolising it. Alcohol will shut down fat burning for 12 to 36 hours, depending on the dose and the individual. This is because the body will oxidise alcohol preferentially over other nutrients.
The liver plays a central role in metabolising alcohol. It stops its other metabolic pathways and concentrates on getting rid of the alcohol. This can lead to alcoholic fatty liver, which can damage the liver and affect how the body metabolises and stores carbohydrates and fats.
To minimise the impact of alcohol on weight loss, it is important to drink in moderation and opt for lower-calorie alcoholic beverages.

Alcohol affects your inhibitions and can lead to poor food choices
Alcohol can affect your inhibitions and lead to poor food choices. Drinking alcohol can lower inhibitions and make it more likely that you will overeat or opt for unhealthy foods. Alcohol can trigger hunger signals in the brain, leading to an increased urge to eat more food.
Drinking can also affect your judgement and decision-making abilities, especially when it comes to food choices. Even the most dedicated dieter will struggle to resist the urge to eat when intoxicated.
To avoid making poor food choices when drinking, it is important to plan ahead. Set a drink limit for yourself before going out and commit to sticking to it. Alternating alcoholic drinks with water can also help reduce alcohol consumption.
It is also a good idea to eat a healthy dinner before drinking, as this can help slow down the absorption of alcohol into your bloodstream and reduce the likelihood of binge eating later in the evening.

Alcohol can cause weight gain around the abdominal area
Alcohol also affects your organs, particularly the liver, which plays a role in metabolising fats, carbohydrates, and proteins. Excess alcohol consumption can lead to alcoholic fatty liver, which can damage your liver and affect the way your body metabolises and stores energy from food. This can make it very difficult to lose weight.
Consuming high-calorie foods and drinks can quickly lead to weight gain, and the body tends to accumulate fat in the abdominal area. Alcohol also lowers inhibitions, making it more likely that you will overeat or opt for unhealthy foods.

Alcohol can negatively impact your sleep
Sleep Deprivation
Research suggests that alcohol can disrupt your sleep cycles, leading to increased periods of wakefulness during the night. This can result in sleep deprivation, which has been linked to an imbalance in hormones related to hunger, satiety, and energy storage. When your body doesn't get enough sleep, you may experience changes in these hormones that can impact your weight loss efforts.
Impact on Fat Burning
Alcohol can interfere with your body's ability to burn fat. When you consume alcohol, your body prioritizes metabolizing it over other substances. This means that instead of burning fat for energy, your body will primarily use alcohol as a fuel source. As a result, the excess glucose and lipids in your body are more likely to be stored as adipose tissue or fat.
Digestive Issues
Alcohol can also affect your digestive function, leading to decreased digestive secretions and slower movement of food through the tract. This can impact your body's ability to absorb and utilize nutrients effectively. As a result, your metabolism may be affected, making it more challenging to lose weight.
Disruption of Hormones
In addition to the impact on sleep-related hormones, alcohol can also affect testosterone levels, which play a role in metabolic processes. Studies have shown that low testosterone levels are associated with metabolic syndrome, which includes high blood sugar levels and a high body mass index. Disruptions in testosterone levels can further hinder weight loss and impact sleep quality, especially in older men.
Strategies for Mitigation
To minimize the negative impact of alcohol on sleep and weight loss, it is important to practice moderation. Set limits on your drinking, have alcohol-free days, and alternate alcoholic beverages with water. Additionally, opting for lower-calorie drinks, such as clear spirits with soda water or a glass of wine, can help reduce the number of "empty calories" you consume.

When alcohol is consumed, the body prioritises metabolising it over other substances. This process can shut down fat burning for 12 to 36 hours, depending on the amount consumed and individual factors.
Yes, moderation is key. Setting drink limits, choosing lower-calorie beverages, hydrating with water between drinks, and maintaining a healthy diet and exercise regimen can help minimise the impact of drinking beer on weight loss goals.
Lower-calorie options include clear spirits with soda water, wine, and cocktails made with fresh ingredients instead of sugary mixers.
While excessive alcohol consumption can lead to weight gain and other negative health consequences, some studies suggest that light-to-moderate drinking may have potential health benefits, such as a reduced risk of heart disease associated with red wine consumption.
