Can drinking alcohol affect your muscle growth (if so, how?)?

Drinking alcohol in and of itself will not affect muscle growth. Some people may notice that when they are in the habit of drinking a lot they are losing muscle mass or are generally more out of shape. This could be for a variety of reasons. One is that drinking alcohol may lead to hangovers and a loss of interest in working out.

After a night of drinking, you may not feel as motivated to exercise or work out really hard. Alcoholic drinks also have a lot of calories which could make someone gain weight and feel more out of shape.
