A journey of how and why people get alcohol induced guts!

24. 1
A 21 year old takes a drink of Alcohol

25. 2
Within seconds, the beverage passes through your esophagus and into your stomach

26. 3
Twenty percent of the alcohol is absorbed from your stomach into your bloodstream; the rest is absorbed from your intestines.

27. 4
The alcohol travels through your blood to your liver, where it’s broken down (metabolized). During this process, waste products called acetate and acetaldehyde are created.

28. 5
Acetate and acetaldehyde signal your body to stop burning fat. At the same time, your body starts MAKING fat from another product of alcohol, acetyl CoA

29. 6
Your body can effectively process only 0.5 to 1 ounce of alcohol per hour.
So the more someone drink, the longer your body is inhibited from burning fat and the more fat builds up from the excess acetyl CoA.
(A 12-ounce beer contains about 0.6 ounce of Alcohol)
