In stage 1 it's impossible to sustain oneself with that(not enough protein), the person will starve/loose weight rapidly and even after a week the intestine won't heal to the point that that one can tolerate solid protein again. I'd say it would take a month of leaky gut rebuilding before one can tolerate solid protein again.
Dr Cambell-McBride recommends 3-5 days on each stage, depending on how you feel, and taking a step backwards if you feel that you have rushed things.
Soups made with bone marrow, fish and meat stock are very nutritious....
From the stage 1 intro diet.....
" Do not use commercially available soup stock granules or bullion cubes, they are highly processed and are full of detrimental ingredients."
" To make good meat stock you need joints, bones, a piece of meat on the bone, a whole chicken, giblets from chicken, goose or duck, whole pigeons, pheasants or other inexpensive meats. It is essential to use bones and joints, as they provide the healing substances, not so much the muscle meats."
"Strip off all the soft tissues from the bones as best as you can to later add to soups or encourage your patient to eat all the soft tissues on the bones."
"The gelatinous soft tissues around the bones and the bone marrow provide some of the best healing remedies for the gut lining and the immune system; your patient needs to consume them with every meal. "
Stage 2 introduces stews and casseroles as well as eggs, so it's only 3-5 days on soups (and these soups contain bone marrow and soft tissue) so there is NO issue about starving.
Thousands have done it so i wouldn't get too bunched up about it.
If you feel it is not for you then try another diet.
“On the First Stage the most drastic symptoms of abdominal pain, diarrhea and constipation will quickly subside.”
“If you suspect an allergy to any particular food, before introducing it do the Sensitivity Test.”
In stage 2, if one is NOT INTOLERANT to egg yolks, provided they eat enough egg yolks and assuming egg yolks require very little digestion then perhaps they will be able to sustain themselves on it. However I'm assuming egg yolks need to be digested like other proteins and are not really elemental?
Gaps intro is NOT an elemental diet. It uses easily digested, well cooked foods, but it is not 'elemental'
Another way of putting it, is that do you think she is saying survive on egg yolks+fat+vegetable soup liquid(without solids) for a month until you can take solid protein again as is found in stage 2?

I know it can be a bit daunting but i'd say give it a go.
It is actually very easy once you get used to the simplicity of it.
I went from eating 5 meals a day and loosing weight to SCD (similar to gaps) and started gaining weight rapidly.
It's not about how much you eat, it's about how much you digest.
Once again, study the web page, you seem to be missing important bits of information (although the 3-5 days is lifted off another site and some other bits of important information may not be on the website, it's still a pretty good free resource).
Maybe buy the book?
It won't work if you don't follow the instructions and i'd hate it if you were one of those few who come back and start ranting against the diet because ”It didn't work even though I almost followed it to the letter except for the toast and the candy and the vegetable oil and the.......”
