Alcohol is a source of empty calories, which means it is calorie-dense but does not provide other nutrients like vitamins and minerals. Pure alcohol contains roughly 7 calories per gram, while carbohydrates and proteins both contain about 4 calories per gram. This means that alcohol provides nearly twice as many calories per gram as carbs or protein and only slightly fewer than fat. Alcohol also reduces energy sources by inhibiting a process known as gluconeogenesis, in which glucose is formed from substances other than glucose. Furthermore, alcohol can disrupt the water balance in muscle cells, altering their ability to produce adenosine triphosphate (ATP), which is the source of energy for muscle contractions.

What You'll Learn
Alcohol is calorie-dense, with around 7 calories per gram
Alcohol is calorie-dense, providing around 7 calories per gram. This is nearly twice the amount of calories provided by carbohydrates and protein, which offer approximately 4 calories per gram. Fat is the only macronutrient that contains more calories per gram, at around 9 calories.
Alcohol is often referred to as "empty calories" because it provides energy but lacks any other nutritional value. It doesn't offer vitamins or minerals, or contribute to muscle growth like proteins and carbohydrates do. The calories in alcoholic drinks primarily come from the alcohol content, rather than any added sugars.
Drinking alcohol regularly can contribute to weight gain, not only because of the calories in the alcohol itself but also because alcohol can increase appetite and reduce feelings of fullness. This can lead to consuming more food, especially those high in fats and carbohydrates, which further increases total calorie intake.
Additionally, alcohol can negatively impact muscle growth and endurance. It disrupts the water balance in muscle cells, affecting their ability to produce adenosine triphosphate (ATP), which is necessary for muscle contraction. Alcohol also reduces energy sources by inhibiting gluconeogenesis, a process where glucose is formed from non-glucose substances.
Therefore, while alcohol provides more calories per gram than proteins and carbohydrates, it is important to consider the overall impact of alcohol consumption on an individual's health and well-being.

Alcohol is an empty calorie as it has no nutritional value
Alcohol is considered a source of "empty calories", which means that while it is calorie-dense, it does not provide other nutrients like vitamins and minerals. Pure alcohol contains roughly seven calories per gram, while carbohydrates and proteins contain about four calories per gram. This means that alcohol provides nearly twice as many calories per gram as carbs or protein and only slightly less than fat, which contains about nine calories per gram. Despite being calorie-dense, alcohol is an empty calorie because it has no nutritional value.
Alcoholic drinks with high alcohol content, larger sizes, and additional sugar and syrup mixers tend to have the most calories. For example, distilled spirits like vodka, rum, whiskey, gin, and tequila are considered the lowest-calorie alcohols as they only contain alcohol and have zero carbs. However, when mixed with sugary drinks, the overall calorie count can quickly increase.
Vodka, in particular, is often touted as a low-calorie liquor with no carbs, fat, or sugar, and no nutritional value. A single shot typically has less than 100 calories. This makes it a popular choice for those on low-carb diets, as the fermentation and distilling processes remove any carbs that were present in the original carb-rich ingredients like wheat and potatoes.
While alcohol provides a significant number of calories, these are considered "empty" because they do not provide any additional nutritional benefits. This is in contrast to whole foods, which provide not only calories but also the nutrients, vitamins, and minerals needed for a healthy body and mind. Thus, while alcohol may contribute to a person's daily calorie intake, it does not offer any health advantages and may even lead to weight gain or nutritional deficiencies if consumed in excess.

Alcohol has nearly twice the calories of carbs or protein
Alcohol is a source of ""empty calories", which means it is calorie-dense but does not provide other nutrients, like vitamins and minerals. Pure alcohol contains roughly 7 calories per gram, while carbohydrates and proteins contain about 4 calories per gram. This means that alcohol provides nearly twice as many calories per gram as carbs or protein and only slightly fewer than fat. For example, a glass of wine with 14 grams of alcohol contains roughly 98 calories.
The number of calories in a drink is primarily determined by its alcohol content, rather than the amount of sugar that is added. Drinks with high alcohol content, larger sizes, and additional sugar and syrup mixers tend to have the most calories. Vodka, for instance, is a low-calorie alcoholic beverage with no carbs, fat, or sugar, and no nutritional value. A single shot typically has fewer than 100 calories. However, it's important to note that sugary mixers can quickly increase the calorie count.
Alcohol may also increase your appetite and reduce feelings of fullness, often leading to the consumption of foods high in fats and carbs, which can rapidly increase total calorie intake. Additionally, alcohol can negatively impact muscle growth and endurance. It disrupts the water balance in muscle cells, altering their ability to produce adenosine triphosphate (ATP), which is the source of energy for muscle contractions. Alcohol also reduces energy sources by inhibiting the process of gluconeogenesis, where glucose is formed from non-glucose substances.
Overall, while alcohol may not seem to provide many calories in terms of grams, it is calorie-dense and can contribute to weight gain, especially when combined with high-fat and high-carb foods.

Alcohol can slow muscle growth and recovery
Alcohol consumption can negatively impact muscle growth and recovery. Firstly, alcohol is a source of ""empty calories", meaning it is calorie-dense but lacks nutrients such as vitamins and minerals. Alcohol contains approximately 7 calories per gram, which is nearly twice the amount of calories per gram of carbohydrates or protein. This contributes to a higher daily calorie intake, potentially leading to weight gain.
Secondly, alcohol disrupts metabolic pathways responsible for energy production. It induces insulin resistance, impairing muscle growth and recovery by limiting the absorption of carbohydrates into muscles. Alcohol also hinders the body's ability to burn carbohydrates and fatty acids by decreasing the availability of necessary molecules. This interference with metabolizing carbohydrates and fats can negatively impact muscle growth.
Additionally, alcohol negatively affects sleep quality, which is crucial for muscle recovery and tissue repair. While moderate alcohol consumption may not impair sleep patterns, excessive drinking can disrupt restorative REM sleep, resulting in daytime drowsiness, fatigue, and poor concentration.
Research suggests that consuming 0.5g/kg of alcohol or less does not significantly impact muscle recovery. However, as consumption increases to 1.5 or 2g/kg, negative consequences are observed, including a decrease in muscle protein synthesis. Therefore, excessive alcohol consumption can hinder muscle growth and recovery, while moderate consumption may have less impact.

Alcohol can increase appetite and reduce feelings of fullness
Alcoholic drinks contain calories, but they are considered "empty calories" as they provide energy with no additional nutritional value. A gram of alcohol averages about seven calories, with an average glass of wine containing more than 100 calories. Vodka is a low-calorie alcoholic beverage with no carbohydrates, fat, or sugar, and no nutritional value. It has fewer calories and carbohydrates than beer, wine, champagne, and pre-mixed cocktails.
Alcohol also affects two other primary hunger-regulating hormones: GLP-1 and peptide YY (PYY). It suppresses the oxidation of fatty acids, which contributes to feelings of hunger since fatty acids play a role in appetite regulation. Alcohol temporarily increases thermogenesis (calorie utilization causing heat production), which means you may feel hungry again more quickly than usual. It stimulates or inhibits neurochemical systems that play a role in appetite regulation.
To reduce the impact of alcohol on your appetite, it is recommended to drink water, eat a nutritious meal before drinking, and prepare a healthy snack ahead of time. Staying hydrated supports the liver and kidneys in processing alcohol and makes you feel fuller, reducing the likelihood of overeating. Eating a nutritious meal before drinking helps slow alcohol absorption, and choosing foods with fiber or probiotics can support gut health and aid digestion.
