The function of drinking beer after fitness is that after alcohol enters the body, it will increase the burden and consume muscles. Beer contains very high calories, and it is alcohol rather than sugar that brings calories, which means that decomposing these calories will be metabolized in the liver instead of directly bringing energy to the muscles.

Beer is made from malt and barley malt as main raw materials, adding hops, liquid gelatinization and saccharification, and then liquid fermentation. It has low alcohol content, carbon dioxide and rich nutrition. Low-molecular-weight sugars and amino acids in beer are easily digested and absorbed, which produces a lot of heat energy in the body, so beer is often called "liquid bread".
