Looks like Slim-Fast is finally getting the message about low carbs. Had an old can of their product around the house and it had 42g of Carbs per one can serving!!

The answer as to whether they stall you is an individual one. Personally, I don't trust Slim-Fast, but so long as you read labels carefully and count correctly they would seem acceptable.

I prefer to make my own shakes by buying protein powder at GNC and adding my own special ingredients; they're especially handy for a quick breakfast.
