Can Alcohol And Weight Loss Coexist?

Alcohol consumption is a favourite pastime for many, but can you lose weight with alcohol in your system? Alcoholic drinks are often referred to as empty calories, providing calories but lacking nutrients. Excess alcohol consumption can lead to liver damage and negatively impact sleep, nutrient intake, digestion, and metabolism. Alcohol also stimulates appetite and lowers inhibitions, leading to poor food choices and increased consumption of high-fat, savoury foods. While it is possible to lose weight while drinking, it is more challenging as the body prioritises clearing alcohol over burning fat. Thus, reducing alcohol intake can support weight loss efforts.

Alcohol contains empty calories

Alcoholic drinks are often referred to as "empty calories". This means that they provide your body with calories but contain 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. These calories are "empty" because they are consumed in addition to the calories your body needs, and the body does not digest them efficiently. While your body can store many nutrients, protein, carbohydrates, and fat, it needs to prioritise getting rid of the alcohol, which is toxic. This interrupts other processes that should be taking place, like absorbing nutrients and processing fat. As a result, you are more likely to store fat around your middle, leading to a "beer belly".

The Foundation for Alcohol Research and Education (FARE) found that the relationship between alcohol consumption and obesity remains unclear. While some studies have found a positive association between alcohol and body weight, this is more likely to be found in men than in women. However, it is important to note that drinking alcohol, particularly in excessive amounts, has many other serious health risks beyond possible weight gain, including high blood pressure, high triglycerides, insulin resistance, heart disease, stroke, liver disease, and some cancers.

In addition to the health risks associated with excessive alcohol consumption, drinking alcohol can also impact weight management. Alcoholic drinks are often high in calories, and these calories are typically additional to the calories consumed in the rest of an individual's diet, rather than a replacement. Alcohol also increases your appetite by reducing your willpower and rapidly increasing and dropping your blood sugar levels, causing more cravings. This can make it challenging to maintain a calorie deficit, which is necessary for weight loss.

Furthermore, alcohol affects the way your body processes fat for energy. While your body can store and utilise nutrients, protein, carbohydrates, and fat, it must first prioritise getting rid of the alcohol, which is toxic. This interruption in normal processes can lead to the storage of fat around the abdomen, which can be particularly harmful as it surrounds important internal organs.

While cutting alcohol out completely may not be necessary for weight loss, reducing alcohol consumption can be beneficial for overall health and weight management. Alcoholic drinks are often high in calories, and these "empty calories" can make it challenging to maintain a healthy weight. By cutting back on alcohol, individuals can enjoy a healthier body, improved sleep, better digestion, and reduce the excess "empty" calories they consume.

Alcohol negatively impacts sleep

While it is technically possible to lose weight while drinking alcohol, it is much harder to do so. Alcohol is often referred to as "empty" calories, as it provides your body with calories but very few nutrients. For example, a 12-ounce can of beer contains almost 155 calories, and a 5-ounce glass of red wine contains 125 calories. Alcohol also increases your appetite by reducing your willpower and rapidly increasing and decreasing your blood sugar levels, causing more cravings.

Additionally, your body prioritizes burning off alcohol over burning fat. As your liver metabolizes alcohol, typically at a rate of about one drink per hour, alcohol remains in your bloodstream. This process can be slow, leaving alcohol circulating in your body. As a result, your body will work to clear the alcohol from your system before returning to burning fat. This makes it challenging to lose weight if there is always alcohol in your system.

Alcohol also negatively impacts sleep, which can lead to weight gain. As a sedative, alcohol increases feelings of relaxation and tiredness, helping you fall asleep. However, as the amount of alcohol in your blood drops throughout the night, you are likely to wake up. This can lead to fragmented, low-quality sleep, leaving you feeling tired the next day. Additionally, alcohol disrupts your sleep architecture, altering the way your body cycles through the four stages of sleep. Specifically, alcohol reduces the amount of restorative rapid eye movement (REM) sleep, which is crucial for healing, memory retention, and feeling rested. As a result, you may experience more vivid or stressful dreams, causing you to wake up more frequently throughout the night.

Furthermore, alcohol can worsen symptoms of sleep apnea, a sleep disorder characterized by breathing interruptions during sleep. By relaxing the muscles in the throat, alcohol increases resistance when breathing, making it more likely for the airway to collapse. This can lead to heavier snoring and a 25% increased risk of sleep apnea, resulting in disruptions throughout the night and lower quality sleep.

Alcohol affects the liver, nervous system, and brain

While it is technically possible to lose weight while alcohol is in your system, it is not recommended due to the negative impact of alcohol on the liver, nervous system, and brain.

Liver

The liver breaks down most of the alcohol you consume so that it can be removed from the body. This process creates substances that are more harmful than alcohol. Large amounts of these substances can damage liver cells and lead to serious liver disease. Fatty liver, where fat builds up in the liver and stops it from working properly, is the most common type of alcohol-related liver disease. This can lead to scarring of the liver (cirrhosis), which can be life-threatening.

Nervous System

Alcohol abuse can result in extensive hospital admissions and has an enormous overall economic cost worldwide. As a small molecule, alcohol can easily cross membrane barriers and reach different parts of the body very quickly. This can lead to disruptions in signals in the brain that affect behavior and mood, making it difficult to think clearly and leading to poor decision-making.

Brain

Alcohol can negatively affect the brain, especially with excess or underage drinking. Heavy drinking slows the cerebral cortex, which takes in and processes new information in the brain. This can lead to difficulties with attention and memory, including blackouts and short-term memory lapses. Multiple episodes of heavy drinking can speed up memory loss and cognitive decline. Adolescents are more susceptible to brain damage from alcohol use, and underage drinking increases the risk of anxiety, depression, and low self-esteem, which can affect the brain long-term.

Alcoholic drinks increase appetite and cravings

Alcoholic drinks are often referred to as ""empty calories", meaning they provide calories but contain very few nutrients. A 12-ounce can of beer contains about 155 calories, and a 5-ounce glass of red wine contains about 125 calories. While it is unclear whether alcohol consumption is a direct cause of weight gain, it has been linked to various health risks such as high blood pressure, high triglycerides, insulin resistance, heart disease, stroke, liver disease, and certain cancers.

Alcoholic drinks can increase appetite and cravings by disrupting the normal functioning of hormones that regulate hunger and satiety. Leptin and ghrelin are two such hormones that signal to the brain when an individual is hungry or full. When an individual consumes alcohol, the body prioritizes breaking down and eliminating ethanol over other processes, such as nutrient absorption and metabolism. This can lead to a delay or decrease in the availability of nutrients, causing individuals to feel hungrier sooner after eating a meal. Additionally, alcohol lowers inhibitions and can lead to poor decision-making, including the choice of high-calorie, nutrient-poor foods.

Furthermore, individuals with alcohol use disorder (AUD) often adopt a diet high in processed foods, refined sugars, and low in fiber, healthy fats, and nutrients. This type of diet makes it harder to meet nutritional needs and can lead to deficiencies in vitamins and minerals, including thiamin (vitamin B1) and folic acid. Alcohol can also cause stomach inflammation and damage to the intestinal lining, further impairing nutrient absorption. The resulting nutritional deficiencies can have serious health consequences, including worsening of liver damage caused by heavy drinking.

It is important to note that the relationship between alcohol consumption and appetite changes is complex. While some sources indicate that alcohol can increase appetite, particularly when consumed in small amounts, heavy drinking is associated with a decrease in appetite. This loss of appetite can lead to nutritional deficiencies and a complicated relationship with food, where feelings of nausea become associated with eating. Additionally, stress and anxiety related to alcohol use can further contribute to a decrease in appetite.

Overall, while alcoholic drinks may increase appetite and cravings in the short term, they can lead to a loss of appetite and nutritional deficiencies with more chronic and excessive consumption. The impact of alcohol on appetite and cravings is just one aspect of the broader health consequences associated with excessive alcohol consumption.

Alcohol can cause intestinal damage

It is possible to lose weight while drinking alcohol, as it depends on the number of calories consumed and burned off. However, alcohol is prioritised over fat as fuel by the body, which makes it harder to burn fat. Alcohol also contains "empty calories", providing calories but very few nutrients. It also increases appetite and cravings by reducing willpower and rapidly increasing and decreasing blood sugar levels.

Alcohol also interferes with the activity of many enzymes that are essential for intestinal functioning, such as lactase, which breaks down the milk sugar lactose. Lactase deficiency results in lactose intolerance. Alcohol also interferes with the enzymes involved in transporting nutrients from the intestine into the bloodstream. Excessive alcohol consumption frequently causes mucosal damage in the upper region of the duodenum, and even a single episode of heavy drinking can result in duodenal erosions and bleeding.

The effects of alcohol on the intestines range from uncomfortable to deadly. Mallory-Weiss tears, inflammation, and ulcers increase the risk of bleeding in the intestines, which can be very serious and even deadly if untreated. The only way to avoid these dangerous impacts of alcohol on the digestive system is to stop drinking as soon as possible.
