Eat a couple of appetizers before toasting, so you’re not drinking on an empty stomach.
Keep in mind that the type of alcoholic drink you choose can raise your calorie intake, too. A 5-ounce glass of white wine, for instance, contains 121 calories, and a 1.5-ounce serving of coffee liqueur has 175 calories—without any mixers you might add.
To cut down on alcohol consumption and calories, you can alternate alcoholic drinks with nonalcoholic offerings or make a lower calorie, less boozy wine spritzer with half wine, half seltzer.
Or, “If you want to look like you’re part of the ‘gang,’ hold a glass of sparkling water with a twist of lemon or lime,” Siegel suggests. “Maybe add a splash of cranberry juice. No one will be the wiser.”
If you prefer a mixed drink, you might want to stick to clear spirits rather than dark liquors. These contain more of a substance called congeners, which scientists think may contribute to hangover severity. In one one study, for instance, when scientists tested how people felt the morning after drinking bourbon or vodka, the bourbon drinkers reported feeling worse.
