Hi Jim,
Those are some interesting thoughts but there are a couple of weaknesses 
in her position:
1. We are all individuals. As such, we each have different protein and 
energy needs. Those needs also vary from day-to-day. I don't think that 
any fixed formula like that will produce the same results for everyone.
2. If fat only comprises 65% of the diet then 35% is made up of 
carbohydrates and proteins. Much of that 35% will also be burned as 
glucose, as excess proteins are converted to glucose, and carbs are 
mostly reduced to glucose. While the body may be using mostly fats for 
energy, it will use some glucose as well. It isn't an on or off thing. 
It is a question of proportions. Typically, the more fats that are 
consumed as energy, the deeper the level of ketosis, but that also 
varies from one individual to the next. My wife and I can eat identical 
meals for several days. She will reach moderate to deep ketosis (40 to 
80 mg/dL) while I will only experience mild ketosis (about 15 mg/dL).
Each of us has fairly unique energy needs. There are smaller variations 
in protein needs, but those also vary considerably.  A friend who is an 
avid body builder has much greater protein requirements than I do.
3. I have been not, to my memory, experienced the 6 week plateau she 
talks about.

Happy New Year to you and all list members.
best wishes,
Ron
