Rudy, I use a whey protein shake powder that's only 1 net carb (7g carbohydrate less 6g fiber) and less than 1g sugar. It's 180 calories, 6g fat, 25mg cholesterol, 80mg sodium, 200mg potassium, 24g protein per serving.
Comes in several flavors.
It's called Walker Diet Shake Mix and the only place I know to buy it is at vitacost.com. It's about $10.99 for an 18.25oz. cannister that makes 11 servings. Flat fee shipping is $4.99 per order.
