Dehydration

The whole human body consists of 70% water and hence, the muscles also need 70% water to stay healthy and fit. Water is thus an efficient part of the muscle building process, and a slight lack of water can affect the muscles very badly. On the other hand, kidneys lose a high amount of water to break down the alcohol that you consume. Thus the more alcohol you consume, the more water is used in breaking them. This causes a high amount of dehydration in your body. Due to such dehydration, your muscle building process is also affected and hence you will fail no doubt as a weight lifter.
