Alcohol consumption is associated with weight gain due to its high calorie content and disruption of metabolism, hormones, and sleep. However, studies have shown that frequent light-to-moderate drinking is not linked to obesity. Binge drinking, on the other hand, is associated with excess weight, especially in women. Alcoholic beverages are often referred to as 'empty calories' because they provide energy without essential nutrients. Additionally, alcohol can trigger hunger signals in the brain, leading to increased food intake and poor food choices. While cutting down on alcohol may aid weight loss, it is not the sole factor, and individual responses vary.
| Characteristics | Values |
|---|---|
| Weight loss | Alcoholic people may lose weight due to the empty calories in alcohol, which provide energy without essential nutrients. |
| Calorie intake | Alcoholic drinks contain calories, with beer containing 150 calories in a 12-ounce glass, wine containing 100 calories in a 5-ounce glass, and distilled alcohol (gin, rum, and vodka) containing about 100 calories in a 1.5-ounce serving. Sweet drinks like pina coladas can contain up to 500 calories in a 7-ounce glass. |
| Metabolism | Alcohol disrupts metabolism by being burned first as a fuel source before the body uses other sources like glucose from carbohydrates or lipids from fats. This can lead to the development of alcoholic fatty liver, which affects the way the body metabolizes and stores carbohydrates and fats. |
| Appetite | Alcohol can increase appetite and influence hormones linked to satiety, such as leptin and glucagon-like peptide-1 (GLP-1). |
| Sleep | Alcohol can disrupt sleep, which is linked to weight gain. |
| Health risks | Binge drinking and heavy alcohol use are associated with an increased risk of obesity and other health problems. |
| Weight management | Reducing alcohol consumption can help with weight management and may support weight loss. |

What You'll Learn
Alcohol contains empty calories
Alcoholic beverages primarily consist of water, pure alcohol (ethanol), and variable amounts of sugars and carbohydrates. Alcohol has a high number of calories, with almost the same amount of calories as fat. A pint of lager contains roughly the same amount of calories as a standard slice of pizza, but the pizza still contains some vitamins and minerals that the body can use for energy. This is why the calories in alcohol are often referred to as "empty calories", as they have no nutritional value and are consumed in addition to the calories your body needs.
The idea of empty calories is that they are just calories, with no micronutrients or fibre. Alcohol does not contain any protein or fat, and the alcohol itself contains 7 calories per gram, which is almost as many as fat. A beer, for example, has approximately 140 calories at 5% alcohol by volume, but the rest is mostly carbohydrates.
The body does not digest the calories from alcohol efficiently. While your body can store many nutrients, protein, carbohydrates and fat, it needs to prioritise getting rid of the alcohol, which is toxic, and this interrupts other processes that should be taking place, like absorbing nutrients and processing fat. This means that you are more likely to store fat around your middle, sometimes referred to as a 'beer belly'. An animal study found that mice given ethanol over a period of three days demonstrated a significant increase in food intake, suggesting that alcohol can trigger hunger signals in the brain.
If you are looking to lose weight, reducing your alcohol consumption can be a good place to start. Drinking less frequently and in smaller amounts can help reduce your overall calorie intake.

Alcohol disrupts metabolism
Alcohol consumption can have a detrimental effect on metabolism, which in turn can lead to weight gain. Metabolism is a term used to describe all the chemical reactions that take place in the body to create energy. Alcohol disrupts this process in several ways.
Firstly, alcohol is burned by the body as a fuel source before glucose or lipids from carbohydrates and fats. This means that excess glucose and lipids are stored as adipose tissue, or fat. Alcohol also affects the liver, which is responsible for metabolising and storing carbohydrates and fats. Excess alcohol consumption can lead to alcoholic fatty liver, which damages the liver and affects the way the body processes and stores energy from food, making it difficult to lose weight.
Alcohol also disrupts the water balance in muscle cells, altering their ability to produce adenosine triphosphate (ATP), the source of energy for muscles to contract. This results in a lack of energy and endurance. Furthermore, alcohol inhibits gluconeogenesis, a process in which glucose is formed from substances other than glucose, further reducing energy sources.
In addition, alcohol can affect the metabolism of medications, increasing or decreasing their effects on the body. This altered metabolism can lead to higher or lower levels of medication in the bloodstream. Heavy drinking can also lead to ketoacidosis, a condition where the body cannot metabolise glucose, resulting in a dangerous accumulation of ketones in the blood.
Finally, alcohol can trigger hunger signals in the brain, leading to an increased urge to eat more food. This, combined with the extra calories from the alcohol itself, can contribute to weight gain. Therefore, reducing alcohol consumption can be an effective way to support weight loss and improve overall health.

Alcohol affects sleep
Alcohol can have a detrimental impact on sleep quality and duration. While alcohol may initially act as a sedative, helping one fall asleep faster, it negatively affects overall sleep quality. As blood alcohol levels rise and fall, alcohol exerts different effects on one's sleep.
Firstly, alcohol is a central nervous system depressant that affects the brain by acting on neurotransmitters, including GABA (gamma-aminobutyric acid). GABA is a neurotransmitter that dampens brain activity, instructing the brain to slow down. Alcohol also impacts other chemicals like adenosine, which prevents the brain from becoming stimulated. These processes produce a relaxed and sleepy sensation. However, as the effects of alcohol start to wear off during the night, one may experience more frequent awakenings, resulting in a restless second half of the night. This rebound effect can cause fragmented or restless sleep, with an increase in REM sleep during the latter half of the night.
Alcohol can also disrupt the normal sleep architecture, which refers to the progression through the different stages of sleep (light sleep, deep sleep, and REM sleep). Studies have found that alcohol consistently delays the first REM sleep episode, and higher doses of alcohol appear to reduce the total amount of REM sleep. Suppressing REM sleep can have detrimental consequences for memory consolidation and other cognitive processes. People who consistently drink too much alcohol may eventually build up a tolerance to its initial sedative effects. Chronic alcohol users typically experience disrupted sleep patterns with less slow-wave sleep and more REM sleep.
Additionally, alcohol can worsen existing sleep disorders. It can increase sleep fragmentation in individuals with sleep apnea, a disorder that causes one to momentarily stop breathing while asleep. Alcohol's relaxing effects can reduce muscle tone in the nose and throat, making it easier for the airway to collapse. Alcohol can also exacerbate insomnia, as individuals may turn to alcohol as a sleep aid, leading to a counterproductive pattern of alcohol use.
Furthermore, alcohol may harm one's circadian rhythm. Normally, the circadian rhythm is responsible for keeping the body anchored to a 24-hour cycle, releasing the hormone melatonin in the evening to prepare us for sleep. However, drinking alcohol before bedtime has been found to lower melatonin levels and interfere with core body temperatures, which in turn impacts sleep quality.
To minimise the impact of alcohol on sleep, it is recommended to consume alcohol at least three hours before bedtime, allowing the body a head start on metabolising it. Drinking less alcohol and moderating one's consumption can also reduce its impact on sleep.

Alcohol increases appetite
Alcoholic beverages are often referred to as "empty calories", as they provide little to no nutritional value. The calories in alcohol are derived from ethanol, a calorie-dense organic compound with about 7 calories per gram, which is nearly as calorie-dense as fat. While one might expect ethanol to promote a feeling of fullness, research shows that it does the opposite, increasing appetite.
Several factors contribute to the increase in appetite after consuming alcohol:
- Alcohol suppresses the breakdown of fatty acids, which play a role in appetite regulation.
- It temporarily increases thermogenesis, or calorie burn, which can make you feel hungry again more quickly.
- Alcohol stimulates or inhibits neurochemical systems that play a role in appetite regulation.
- It lowers inhibitions and impairs decision-making, making it more difficult to make healthy food choices or control portions.
Research in mice has also shown that alcohol activates brain pathways linked to starvation, increasing hunger and appetite. This may explain why people tend to eat more when they have been drinking.
While cutting out alcohol completely is not necessary for weight loss, reducing alcohol consumption can be beneficial for weight management and overall health.

Alcohol affects hormones
Alcohol affects the body's hormone production and regulation. It disrupts the finely tuned workings of the endocrine system, which can lead to health issues and imbalances. For example, excessive alcohol consumption can elevate levels of cortisol and other stress hormones. Cortisol is the hormone that triggers the body's built-in fight-or-flight response, and higher levels can lead to increased anxiety, weakened immune function, and premature ageing. In addition, alcohol lowers testosterone production, affecting sexual function, muscle mass, and mood in men.
Alcohol also impacts the hypothalamic-pituitary-gonadal axis, resulting in decreased libido and fertility issues. This can lead to a range of outcomes, including decreased libido, infertility, and gonadal atrophy. Furthermore, alcohol abuse in women can lead to estrogen dominance, where the ratio of estrogen to progesterone rises too high. This can cause irregular periods and changes in menstrual flow, and it may also contribute to the development of tumours in the uterus lining and dense breast tissue.
The adrenal glands, which produce steroid hormones that regulate metabolism and blood pressure, are suppressed by alcohol. Regular consumption can lead to adrenal fatigue, decreased ability to fight off diseases, increased food cravings, weight gain, dampened sexual response, and higher blood pressure.
Alcohol also affects the way the body metabolises nutrients, as it is burned first as a fuel source before the body uses anything else. This can lead to excess glucose and lipids being stored as adipose tissue or fat. This can make it challenging to lose weight.
While the amount of alcohol consumed may not directly impact weight loss, excessive drinking can lead to weight gain and other health issues. Binge drinking is associated with an increased risk of obesity, especially in women. Alcohol can also affect decision-making, leading to poor food choices and increased food intake.
