Episode notes

Alcohol is considered empty calories because it is metabolically costly but lacks nutritive value. It can only be used for immediate energy and cannot be stored in a beneficial way. Additionally, alcohol does not provide essential nutrients such as vitamins, amino acids, or fatty acids, making it truly empty calories. While some people refer to sugar as empty calories, it actually serves as a better fuel source than alcohol. When alcohol is ingested, a percentage is directed into a worse poison and some is used as a fuel source.

In this episode, I discuss the physiological effects that drinking alcohol has on the brain and body at different levels of consumption and over time. I also describe genetic differences that predispose certain individuals to alcoholism, binge and habit-drinking. I explain alcohol metabolism in simple terms and how it effectively acts as a poison, leading to cellular stress and damage. I then explain that it impacts neuronal function and changes our thinking and behavior – hallmarks of inebriation. I also discuss how alcohol consumption of different amounts impacts inflammation, stress, neurodegeneration, and cancer risk and negatively impacts the gut microbiome, brain thickness, hormone balance, mood and feelings of motivation. Additionally, I discuss the biology of hangovers and describe science-based strategies to mitigate the severity of a hangover. Since alcohol is one of the most widely consumed recreational substances, this episode ought to be of relevance to everyone. Indeed, even low-to-moderate alcohol consumption negatively impacts the brain and body in direct ways. The goal of this episode is to help people make informed decisions about their alcohol consumption that are in keeping with their mental and physical health goals.
