I did the ND on Atkins shakes. There are only two flavours, chocolate and vanilla. They are both ok taste wise, but they are powdery and no amount of shaking will change that. I made mine with water not milk to keep the carbs down. They are expensive compared to other meal replacement shakes, but they do the job on minimal carbs, so while bored with only two flavours, they did what I wanted them to do.
