Dr. A is ok with low-fat/low-carb..and I quote..

DANDR part 5 , the "Dr. Atkins and I" menu

...many of the recipes are loaded with butter, cream, and egg yolks. This
might give you the misleading impression that that's what I want you to eat
all the time, which is not the case. Unless you are on the special Fat
Fast, eating lean foods is quite appropriate.
