carb

   1. an informal unit used in the treatment of diabetes, equal to 15 grams of carbohydrates. This unit is known under various names, including carbo, carb unit, choice, or exchange. The significance of 15 grams is that in a very rough way that quantity of carbohydrate requires about 1 unit of injected insulin for patients with Type I diabetes (the actual ratio between carbohydrate and insulin varies considerably from patient to patient and is usually much lower for patients with Type II diabetes).
   2. an informal unit equal to 1 gram of carbohydrate, commonly used in describing low-carbohydrate diets such as the Atkins diet. This newer usage of the term "carb" conflicts with the traditional use by diabetics (previous entry).
