Grapefruit diet question.

I read about something called the Grapefruit diet,where you drink a
glass of grapefruit juice before each meal. However in the diet there
is a strict list of food menus you have to eat. My finances are
streched right now,so is there anyway I can cheat and do the diet,but
without following the foods listed? I mean, maybe I can just eliminate
all carbs and only eat fats and protein, but without following the
exact requirements listed in the diet,like having 2 strips of bacon
for breakfast etc etc?
Anyone tried the grapefruit juice diet,did it do any good?
Thanks and bye.
