I was reading in a home brewers thread that a guy was trying to brew a carb-free IPA. Then people started flaming him with things like "alcohol is a carb" and "you don't know your chemistry." Then I thought to myself, alcohol is not a carbohydrate, it's a completely different form of calories by itself. From my memory, I thought that the only 4 ways one can intake calories was protein, fat, carbohydrates, and alcohol. Also, you can drink alcohol on the Atkins diet and still not stop ketosis permanently. Carbs and alcohol act differently on the blood sugar as your body breaks them down differenly, so how can alcohol be a carbohydrate? So, am I right or are the others right?
