One of my favorite blogs posted a great guide to smart alcohol consumption for the new year. Many health professionals persuade alcohol abstinence. While this may be no sweat for some, its good to figure in some of your regular behavior when considering healthy choices.
It is possible to indulge from time to time and you shouldn't have to skip out on traditions or social events all together because you're looking to get fit. This guide I found does a good job at reminding us about the most important rule while drinking, to be smart and responsible.
Having a good healthy meal before you go out for the evening will act as a good base to protect your organs against alcohol damage. Avoid mixed drinks and dark beers as both can pack on the calories. In addition, don't be afraid to ask for water between drinks. It can lessen the amount of alcohol you actually take in if you slow your night down and play it smart.
In addition, remember that other drinks can be heavy in calories as well. Juices, soft drinks, and coffee drinks (with additives) all pack a mean calorie punch to your diet.
