I really dona't know anything about Rum. You may want to check the Bacardi website to get more info.

Vodka has 0 carbs. Once in a great while I like to mix the citris vodka with a diet squirt. It's really good.

Most of the hard liquors have 0 carbs.

One thing I do know is when you drink alcohol, you may stall since your body will burn the alcohol prior to burning the fat.

HTH a little.
