If increasing muscle mass is one of your goals, then think twice before you go out for a night of heavy drinking.
Consuming alcohol in large quantities has a direct effect on your metabolism, causing fat to be stored instead of being utilized as an energy source.
Alcohol contains seven “empty” calories per gram, meaning that these calories don’t provide you with any of the essential nutrients you need to build that muscle mass you desire.
