If one shot of whiskey has no carbs, fat or protein, where do those calories derive from??

I just dont understand how alcohol has calories and no dietary composition... where do those calories come from? are they mre simplex than sugar? is that why it makes you fat?

i asked the same question when i was on the Atkins diet...which lists most alcohols as zero carbs.

Apparently alcohol (while I classed it as a carb) is not a standard carb. Sort of like Maltitol (which is a sugar knock off) that does not come under "sugar" or "carbohydrate" on nutritional panels because it does not affect blood sugar levels. So alcohol is a sugar, but not really when it comes to digestion. OMG its sooo confusing. What I can say is that whiskey and vodka didnt kick me out of ketosis on Atkins which means yes, there is no sugar in them...*Shrug*

it is the sugar. To make alcohol in any form you have to have sugar.

Sugar

The alcohol silly! Calories are figured by the following formula:
Cals = fat X 9 + (carb - fiber) X 4 + protein X 4 + alcohol X 7


Plus your body cannot burn fat for about 24 following your last drink. Hence how you can get fat!
