While traveling on cruise ships, socially drinking alcohol is common place. Fat loss and calories from drinking alcoholic beverages is not the norm. People have been lead to believe that an alcoholic drink automatically adds calories to the body. That is not exactly correct.
As long as you are aware of the calorie intake you are receiving from your drinks, you can compensate in your daily diet to offset the minimally consumed calories from a few drinks. Thus staying on track with your fat loss goals can be accomplished even with a few infrequent drinks. Just try to resist the open bars and the consumption of more than one or two drinks an evening.
