In most countries outside the USA fibre is not counted as being a carbohydrate at all, therefore has not been counted in the 'total carb' bit of our labels.
The clue is where it is listed in the label
Here is a UK type of label - you will see the fibre is listed in a seperate section of t he nutrition panel from the carbohydrates. I am fairly sure Australian labels follow the same rules as ours.
And here is a USA type label where the fiber is listed among the carbohydrates
BTW Dr Atkins did mention the carbs in eggs and in the list at the back of DANDR had an egg as having 0.6 net carbs.
As for the shakes, they tend to be high in protein as compared with their fat content and so might throw your ratios out by overloading you with protein. So once you are at the OWL rung that allowa ALL the ingredients and decide to use them you will probably need to add fat to balance them and get your 65% fat/30% protein/5% carbs percentages for induction. These percentages are not mentioned in DANDR but were arrived at by a Dukes University analysis of the menus for induction in DANDR.
