If you are trying to lose weight DON’T drink any alcoholic beverages at all. Hard liquor has no carbs, but converts to carbs once you drink it. Your body will use up this energy first before attacking any food calories you have eaten. That said, with respect to weight loss, there is no difference between the hard liquors, they all have about the same calories per shot, I think about 90.
