I love the Dannon Carb Control yogurt. It comes in 1/2 cup servings and is not made with sugar and uses Splenda. I just checked and each serving has 3 grams of carbs. My favorite is the raspberry.

Hood makes a low carb yogurt too that has Atkins approved on the package. I didn't like it as much as the Dannon. Dannon is very creamy.

Hope this helps!!
