What’s alcohol?

Alcohol contains seven calories per gram, almost twice the level of protein and carbohydrates, and just 2 fewer calories. Alcohol calories therefore raise our fat storage and lack the nutrients advantageous to get a healthy metabolism and can also be empty.
What goes on when we drink booze?

After drinking alcohol, around 20% is absorbed into the blood stream as well as the rest is taken through the little intestine into the blood stream. Alcohol is normally absorbed pretty quick, however these particular variables can influence this rate of absorption:
The variety of beverage e.g champagne is consumed more rapidly than non sparkling beverages.
The larger the alcoholic concentration the faster the absorption.
Most of the alcohol in the blood stream gets processed in the liver where the alcohol is broken down by the enzyme alcohol dehydrogenase (ADH, which is contained in the liver). ADH then metabolises the alcohol. Acetaldehyde is broken down into acetate by another enzyme, aldehyde dehydrogenase.
The microsomal ethanol oxidising system begins to break down a tiny portion of alcohol using an alternate pair of enzymes, when blood quantities are high. The remaining small percentage of alcohol is lost through urine, sweat and breathing.
The most essential negative function of alcohol is the suppression. Testosterone is a rather anabolic hormone which contributes to lean body mass therefore less testosterone means less muscle, and less muscle means less calories being burned.
Hydration of muscle cells is essential when attempting to boost muscle tissue. These muscle cells are dehydrated by alcohol and being dehydrated can seriously hinder your performance.
Alcohol also blocks the absorption of many important nutrients which are affected in muscle contraction, relaxation and development iron and potassium.
In overview:

Dehydration is caused by alcohol.
Testosterone levels are reduced by alcohol.
Oestrogen levels increase.

Alcohol blocks the absorption of nutriments involved in muscle functions.
Basically, if your’e wanting to lose fat your’e got to cut the booze out completely. Even little quantities lower Testosterone up to 25% which has powerful impacts on the metabolism and encourages fat storage.
