How is Alcohol Linked to Weight Gain?

While there is limited evidence that directly links alcohol to weight gain, a connection has been identified. Globally, 16% of adults are classified as obese, and 43% are considered overweight. 

Drinking alcohol can contribute to increased body weight, as both alcohol and obesity negatively impact an individual's body mass index (BMI), leading to a higher-than-healthy BMI.

How Many Calories are in Alcohol?

Different types of alcoholic drinks vary in calorie content, with some being higher than others. Many alcoholic beverages are produced through fermentation, using starches, sugars, and grains. 

Alcohol also contains “empty calories,” meaning it provides energy but lacks essential nutrients like vitamins or minerals.

Alcohol has seven calories per gram, but this doesn’t factor in the drink size, added mixers like tonic water or soda, or how many drinks you consume during a meal. These extra calories can quickly add up, especially if you prefer mixed drinks.

Here’s a breakdown of the calories in various alcoholic beverages:

How Can Alcohol Lead to Weight Gain?

Alcohol can contribute to weight gain in several ways. 

First, as an alcoholic beverage, it reduces your feeling of fullness from solid food, leading you to eat more than usual. 

Second, alcohol affects metabolism. When consumed, the body prioritizes metabolizing alcohol over other foods. 

This means that while your body is busy processing the alcohol, the nutrients and calories from solid foods are stored as fat. In essence, consuming alcohol can overshadow the benefits of nutritious foods and promote weight gain.

How does the body process alcohol?

When you consume alcoholic beverages, your body undergoes a specific process to metabolize the alcohol. Here's a step-by-step breakdown of how your body processes alcohol:  

1. When alcohol is ingested, it enters the body as ethanol.  

2. Ethanol is converted into a toxic compound called acetaldehyde by the enzyme called alcohol dehydrogenase. Acetaldehyde is what causes hangover symptoms like nausea, vomiting, and facial flushing.  

3. Acetaldehyde is then broken down into a less harmful substance called acetate.  

4. Acetate is eventually excreted from the body as carbon dioxide and water.  

5. People who want to quit drinking can use medications like disulfiram, which block the conversion of acetaldehyde into acetate. This causes hangover symptoms to occur much earlier during alcohol consumption, discouraging further drinking.

How Much Alcohol Do You Need to Drink to Gain Weight?

While no specific amount of alcohol directly causes weight gain, alcohol consumption combined with a sedentary lifestyle and poor eating habits can lead to increased body weight. 

Regular alcohol intake can also contribute to alcohol use disorder (AUD), a condition where problematic drinking patterns impair daily functioning. 

AUD often results in consuming larger amounts of alcohol to achieve the same effects, leading to greater alcohol intake over time, as well as more weight gain.

How Can Drinking Alcohol Make You Gain Weight?

Drinking alcohol can cause weight gain both directly and indirectly. It impacts your metabolism and can impair your decision-making. Here are a few ways alcohol can increase body weight:

Drinking alcohol and increased food intake

Drinking alcohol not only impacts your body directly but also influences your food choices and eating habits in the following ways:

• Increased appetite: Alcohol affects how satisfied you feel after eating. Foods that would normally curb your hunger might no longer feel sufficient, leading to overeating.

• Lowered inhibitions: Alcohol lowers your ability to make mindful decisions, including what you eat. You might find yourself indulging in foods you normally avoid, or even eating something you're allergic to, as alcohol impairs judgment.

• Unhealthy bar food: Common snacks like chicken wings, nachos, pretzels, and peanuts, which are often found in bars, are typically high in calories and unhealthy. When paired with alcohol, it's easy to lose track of how much you're eating, leading to weight gain.

Alcohol and the ‘beer belly’ effect

Alcoholic beverages are high in calories, which are quickly converted into fat. This fat tends to accumulate in fat cells, particularly around the abdominal area in men, leading to the characteristic "beer belly" often associated with alcohol consumption. 

However, this condition – known as central obesity – can result from various factors and is not always caused by alcohol consumption alone.

Health conditions that cause weight gain

Regular alcohol consumption can lead to health conditions that cause weight gain, among other issues.

Liver disease

Liver disease caused by excessive alcohol consumption can lead to weight gain because the liver plays a vital role in metabolizing fats and processing nutrients. 

When alcohol damages the liver, its ability to break down fats is impaired, leading to fat accumulation in the body, especially around the abdomen. 

Additionally, liver disease can cause fluid retention and bloating, further contributing to weight gain. 

Regularly drinking can worsen these issues, as the liver becomes overworked and less efficient in processing not only alcohol but also the fats and nutrients from food.

Metabolic syndrome

Metabolic syndrome is a group of conditions that include high blood pressure, elevated blood sugar, excess abdominal fat, and abnormal cholesterol levels, all of which raise the risk of heart disease, stroke, and type 2 diabetes. 

Alcohol consumption can contribute to the development of metabolic syndrome by increasing abdominal fat, raising blood sugar levels, and negatively impacting cholesterol and triglyceride levels. 

Regularly drinking alcohol, especially in excess, can worsen these conditions, leading to weight gain and further complicating the body’s ability to regulate fat and sugar metabolism. 

Insulin resistance and type 2 diabetes

Heavy drinking can cause insulin resistance, making it more difficult for the body to control blood sugar levels and raising the risk of type 2 diabetes.

Alcohol is high in empty calories and promotes fat storage, particularly around the abdomen, which is linked to insulin resistance. Over time, regular alcohol intake not only raises the risk of insulin resistance but also contributes to weight gain.

Sleep disorders

Alcohol consumption can disrupt the sleep cycle, leading to sleep disorders like insomnia or fragmented sleep. 

While alcohol may initially help you fall asleep, it interferes with deeper stages of sleep, reducing sleep quality and leaving you feeling fatigued. 

Poor sleep triggers hormonal imbalances, particularly in ghrelin and leptin — hormones that regulate hunger and fullness. 

This imbalance can lead to overeating and cravings for high-calorie foods, contributing to weight gain. 

Depression

Depression can lead to emotional eating, often causing overeating, especially with calorie-dense comfort foods. 

Alcohol can worsen depression by altering brain chemistry and increasing feelings of sadness. This cycle of emotional eating and alcohol use can result in weight gain and other health issues.

Additionally, medications such as antidepressants commonly prescribed for depression can contribute to weight gain by increasing appetite. 

The combination of emotional eating and increased appetite from medication can make managing weight more challenging for those struggling with depression.

Will You Lose Weight If You Stop Drinking?

When you stop drinking, your body may replace one habit with another, so weight loss isn’t guaranteed. 

While cutting out alcohol can reduce your calorie intake and potentially lead to weight loss, it largely depends on your overall eating habits and activity level. 

You're more likely to lose weight by combining alcohol reduction with healthier lifestyle choices.

Healthier alternatives to alcohol

Consider exploring nonalcoholic versions of your favorite drinks and experimenting with different flavors. 

If alcohol has been your go-to for managing stress or tension, finding new outlets can be helpful. 

Walking, pilates, or other mindful physical exercises can provide a calming and healthier alternative. 

If your relationship with alcohol feels more serious, it may be worth considering alcohol detox to kickstart your journey toward healthier habits.

When Should You See a Doctor to Lose Weight?

You should see a doctor to help you lose weight in the following cases:

• Disordered eating: If you’re using diuretics, laxatives, or other unhealthy ways to lose weight, you may have an eating disorder that a healthcare provider should address.

• Struggles despite consistent effort: If you’ve been eating well and staying active but still can’t seem to lose weight, there may be underlying health issues that a doctor can help diagnose.

• You need to lose weight for a procedure: Weight loss may be necessary before surgery, as a higher BMI can make procedures more complex and risky.

• Your joints are being affected: Excess weight can lead to back and joint pain, sleep apnea, body image issues, and gastroesophageal reflux disease (GERD).
