Alcohol is detrimental to diet. It is purely empty calories that don't even get used by the body for fuel at all. I think I read somewhere that your body even halts the use of its normal fuel sources to get rid of the alcohol in your system first (feel free to correct me if I'm wrong. anybody). However, I think it's okay as long as you don't drink too much and/or too often. I stay away from beer, though, since it has a lot of extra cals on top of the alcohol and you have to drink a considerable amount to get a decent buzz going. I stick with wine or liquor. 2 small glasses of scotch on the rocks or 2 glasses of vino usually gets me comfortably toasty.
