What are its short term effects?
When a person drinks alcohol, it is absorbed by the stomach, enters the bloodstream, and goes to all the tissues. The effects are dependent on a variety of factors, including a person’s size, weight, age, and sex, as well as the amount of food and drink consumed. We all know the potential side effects of alcohol consumption.
Effects On Fat Metabolism
For several hours after drinking the vodka, whole body lipid oxidation (a measure of how much fat your body is burning) dropped by 73%.
The reason why alcohol has this dramatic effect on fat metabolism has to do with the way it is handled in the body. When it is consumed, it readily passes from the stomach and intestines into the blood and goes to the liver. In the liver, an enzyme called alcohol dehydrogenase mediates the conversion of alcohol to acetaldehyde.
Acetaldehyde is rapidly converted to acetate by other enzymes. So rather than getting stored as fat, the main fate of alcohol is conversion into acetate, the amount of acetate formed is dose dependent on the amount of alcohol consumed. And it appears this rise in acetate puts the brakes on fat loss.
So the body simply burns the acetate first, and then basically pushes fat oxidation out of the metabolic equation.
