Shortly before starting my third year of college, I reconnected with some people from high school who I had not seen since they had gone on to higher education in other parts of the country. I am by no means a saint, but living at home is not like living away from home in college. Living away from home is an opportunity for minimal inhibitions and easy access to alcohol. When I laid eyes on some of my friends, my eyes almost popped out of their sockets. Most of them were athletes or simply lean in high school, but in just 2 years most of them had added between 20 and 100 lbs. Alcohol was the common culprit. Beer was the weapon of choice.
Alcohol is a dastardly fellow because of its ability to hamper your body’s ability to metabolize fat. To understand how alcohol has such a dramatic effect on fat metabolism, we need to know how your body handles the stuff. Alcohol, like most liquids, easily passes from the stomach and intestines and is absorbed into the blood and filtered through the liver. In the liver, a number of enzymes we’ll collectively call alcohol dehydrogenases help break the alcohol down and convert it into acetaldehyde, and then into acetyl CoA, but we’ll just call it acetate. A residual amount of alcohol remains unmetabolized and is flushed out of the body in other ways, such as urine or through exhalation while breathing. The amount of acetate created depends on how much alcohol was consumed. And here is why that is important: The spike in acetate is what effectively puts the breaks on fat loss.
For the most part, what you feed your body is what it uses as a source for fuel, and the type of fuel your body uses is generally determined by availability. In other words, your body tends to use whatever you feed it for fuel and will get accustomed to the nutrient intake through adaption. However, when acetate levels rise, your body will prefer to use up the acetate as excess acetate results in fatty acid synthesis. That is, alcohol eventually gets converted into nice, cheap energy that required less metabolic work to produce than calling on existing fat storages.
Alcohol is basically a cheap alternative fuel for our bodies that is void of nutritional value. Does this help us in our pursuit of leanness? Well, no. Do I expect everyone will give up alcohol entirely? Well, no. But the more you know the better equipped you are to make good decisions as you head into your weekend.
