When trying to watch your calorie intake, social drinking is a difficult decision. Those calories have no nutritional value at all. But with holidays and family gatherings it's hard to be the one sitting there sipping on a diet 7 up when someone breaks out the beer and seven layer dip.
But you can still have an occasional drink and still be healthy. Simply choose a drink without a lot of added sugar and calories and keep your drinks to one or two at a party.
I don't know if I could actually be satisfied with 3.5 ounces of wine. But give me an ounce and a half of good whisky with a splash of water, and I'm good for the party. Avoid anything mixed with sugary soda or syrups, and drink a large glass of water for each serving of liquor you consume.
Because that will leave you more calories for dessert. (Such as this light dessert - a small chunk of fat free angel food cake topped with strawberries, 1/4 cup vanilla ice cream and drizzled with honey, served in an elegant martini glass).
