Understanding Alcohol as a Macronutrient

Why Alcohol Is Considered a Macronutrient

A macronutrient is any substance that provides energy (calories) for the body. Like carbs, protein, and fat, ethyl alcohol (ETOH) provides calories:

• Carbohydrates: 4 calories per gram

• Protein: 4 calories per gram

• Fat: 9 calories per gram

• Alcohol: 7 calories per gram

  
  

The big difference? Unlike carbs, protein, and fat, the calories from alcohol are NOT essential for survival.

How the Body Processes Alcohol

1. Absorption: About 20% of alcohol is absorbed quickly through the stomach lining into the bloodstream, with the remaining 80% absorbed through the small intestine.

2. Transport: Once in your bloodstream, alcohol circulates throughout the body, affecting the brain, liver, stomach, pancreas, and other organs.

3. Metabolism:

   • The liver does most of the heavy lifting...

   • First, the enzyme alcohol dehydrogenase (ADH) converts alcohol into acetaldehyde (a toxic byproduct).

   • Acetaldehyde gets broken down into acetate, which is less toxic.

   • Finally, acetate is converted into water and carbon dioxide, which the body can eliminate.

4. Elimination:

   • A small percentage (~2-5%) of alcohol is excreted unchanged in breath, sweat, and urine. This is how breathalyzer tests work.

   • The rest is metabolized in the liver at a fairly constant rate (about one standard drink per hour).

     
     

Your body treats alcohol like a toxin to get rid of first, leaving everything else on hold. It will prioritize metabolizing alcohol above all other nutrients, medications, supplements, etc.

How Many Calories Are in a Drink?

On average, one standard drink contains about 15 grams of alcohol, which equals roughly 105 calories. That’s before you add mixers, sugar, or cream.

Downsides of Alcohol

While enjoying a drink can be part of social experiences, it’s important to be aware of the downsides:

• Nutrient absorption: Alcohol interferes with the absorption of not only macronutrients but important vitamins and minerals, especially B vitamins, zinc, magnesium, and folate.

• Muscle recovery and growth: It reduces protein synthesis and can hinder recovery, leading to loss of lean muscle mass over time, as well as slow fat loss and/or increase the likelihood of gaining fat mass.

• Hydration: Alcohol acts as a diuretic, increasing fluid loss and contributing to dehydration.

• Gut lining damage: It irritates and inflames the intestinal barrier, which can lead to intestinal permeability or “leaky gut” and worsen digestive symptoms.

• Microbiome imbalance: Alcohol disrupts the balance of healthy gut bacteria, making it easier for harmful microbes to thrive.

• Altered Motility: Depending on the type and amount, alcohol may slow digestion (causing constipation) or speed it up (leading to diarrhea).

• Reflux and heartburn: Alcohol relaxes the lower esophageal sphincter, increasing the likelihood of acid reflux.

• Liver strain: The liver must prioritize metabolizing alcohol before anything else, which can increase the long-term risk of liver disease.

• Sleep disruption: Alcohol suppresses REM sleep cycles, leading to lighter, less restorative sleep. And yes, even with 1-2 drinks.

  
  

How to Minimize Negative Effects

If you choose to drink, here are some tips to minimize the negative effects:

• Stay HYDRATED: Drink plenty of water and electrolytes to combat dehydration.

• Eat a well-balanced meal BEFORE drinking: This helps slow absorption, reduces impacts on blood sugar, and maximizes nutrient absorption.

• Nourish your liver: Include plenty of colorful produce for antioxidants, and get a variety of foods like leafy greens, nuts, seeds, fruits, and vegetables.

• Mind the timing: Give your body time to process alcohol (remember, it takes about one hour to clear a standard drink).

• Limit frequency and amount: The fewer and smaller the doses, the less cumulative strain on your body.

  
  

Conclusion

Understanding the role of alcohol as a macronutrient can help you make informed choices. By being aware of its effects on your body, you can enjoy it responsibly while prioritizing your health. Remember, moderation is key, and taking care of your body should always come first.
