A habit of drinking shouldn’t lead to long-term consequences for your health. However, weekend drinking can lead to alcohol dependence and other serious medical conditions.

Binge drinking in the United States is nothing new—one in six adults are binge drinkers.1 Unfortunately, exceeding the maximum recommended limit of moderate alcohol consumption can have severe health consequences.

If you’re at risk of an excessive drinking habit and want to avoid long-term health risks, this guide is for you. Learn more about the consequences of binge drinking and how to prevent alcohol addiction.

Is It Okay to Drink Alcohol Once a Week

Knowing whether drinking alcohol once a week is okay ultimately depends on how much you consume. You should also consider risk factors like having a history of heart disease or high blood pressure.

To determine whether once-a-week drinking habits are sustainable, it's best to understand moderate drinking and how drinking alcohol weekly impacts your health.

What Is Moderate Drinking?

According to the Dietary Guidelines for Americans, moderate drinking is the consumption of no more than two drinks daily for men and one drink daily for women.2

Limiting alcohol use to a moderate level reduces the risk of alcohol-related harm.

How Does Weekly Alcohol Consumption Impact Health?

While consuming one or two drinks a week isn’t immediately dangerous, it can result in the following short-term risks:

  • Injuries from impairment (motor vehicle crashes, slips, falls)3
  • Risky sexual behaviors and violence4
  • Miscarriages, stillbirths, or fetal alcohol spectrum disorders (FASDs)5

Long-term risks associated with light drinking patterns include the following:

  • Developing cancer of the mouth, throat, breast, liver, colon, and rectum6
  • Liver damage7
  • Learning and memory issues8
  • Weakened immune system10
  • Mental health issues, such as depression and anxiety11
  • Development of Alcohol Use Disorder (AUD), should the number of drinks increase over time11

Understanding the Liver's Role in Alcohol Metabolism

The liver is the largest internal organ in the body and is responsible for breaking down alcoholic drinks.12 When you drink a glass of wine or liquor, 25% of the alcohol travels directly from the stomach and into the bloodstream. An enzyme in the liver cells called alcohol dehydrogenase (ADH) breaks the substance down into acetaldehyde.

Another enzyme, aldehyde dehydrogenase (ALDH), breaks the acetaldehyde into acetate. Once the liver metabolizes it, the acetate leaves the body as carbon dioxide and water.

Depending on genetic variations and other existing health problems, your enzymes may or may need to be more efficient at breaking down alcohol.

How Much Alcohol Is Safe for the Liver?

The more alcohol you consume, the longer it takes for the body to process it. Determining a “healthy number” of drinks for the liver depends on a person’s weight, size, and gender.13

Because it takes the body an hour to process a single standard drink, consuming one to three drinks per day can cause significant damage to the liver. Heavy drinking (four to five glasses of alcohol daily on average) can lead to health complications, including:14

  • Alcoholic cirrhosis
  • Hepatitis
  • Liver failure

Can Drinking Once a Week Impact Weight and Fitness?

Older adults aren’t the only ones at risk of developing risky conditions or dying prematurely due to alcohol consumption. There is a direct correlation between the amount of alcohol you consume and your fitness level.16

Alcohol consumption hampers overall fitness and performance levels, affecting endurance, reaction times, hydration, muscle development, and hydration.

Does Alcohol Cause Weight Gain?

Alcohol can cause weight gain by keeping the body from burning fat. The body has to work harder to eliminate pure alcohol, deprioritizing other healthier nutrients.

Because the body recognizes toxic chemicals in alcoholic drinks, it temporarily halts its ability to access other stored macronutrients.

Other ways alcohol use causes weight gain include the following:

  • It’s high in calories: While proteins and carbohydrates have four per gram, alcohol has seven.17
  • It impairs hormone gland function: Even moderate drinkers are at higher risk of producing increased amounts of cortisol, a hormone that causes weight gain.18
  • It leads to poor sleep quality: Alcohol use disorder causes insomnia symptoms, leading to weight gain over time.19

How Does Weekly Drinking Affect Fitness Levels?

Participating in weekend binge drinking can affect your fitness levels in the following ways:

  • It reduces the body’s ability to convert food into energy: When carbohydrates and blood sugar levels drop, athletes experience reduced aerobic performance.20
  • It acts as a sedative: Binge drinking causes poor hand-eye coordination and slower responses.21
  • It halts human growth hormone (HGH) production: The less HGH your body produces, the poorer its muscle-building and repair processes.22
  • It makes the recovery period longer: Binge drinking increases bleeding and swelling around soft tissue injuries.22
  • It promotes water loss: Antidiuretic hormone production decreases, causing you to urinate more and become dehydrated.23

Are There Any Benefits to Drinking Certain Types of Alcohol?

While binge drinking isn’t a healthy choice in general, some types of alcohol are safer to consume than others:

  • Red wine: This alcohol is a fuel source for good bacteria, improving immune system function and heart health.23
  • Champagne: Plant compounds in sparkling white wine can benefit heart health.24 It’s also low in carbs, calories, and sugar.
  • Craft beer: When consumed in the form of ale or lager, craft beer can provide an ample level of protein and B vitamins.25

Some alcoholic beverages can be beneficial when consumed in moderation. For instance, red wine, whiskey, and hard kombucha can provide the following benefits:

  • Boosted brain health
  • Better bone density
  • Lower risk of heart disease
  • Lower cholesterol levels

Remember to limit the amount of alcohol you consume weekly to maximize its health benefits.

To answer the question, “Is drinking once a week bad?”—Drinking once a week can be bad or good, depending on what and how much you drink. It’s also vital to consider your medical history, lifestyle, and diet.

Common Questions About Regular Drinking

While it’s “OK” to get drunk once a month, turning it into a habit can lead to alcohol abuse and dependency.
