You seem to have your panties all twisted up or something.
I know it's nothing like a prep and that is my stance. I am a chef, so cooking anything is quite easy.
GFD: get a bunch of veggies and between 4-6 eggs, cook, eat.
Prep: pre calculate my macros. Split said macros for the day. Cook exactly 2 eggs, 6 egg whites, 1/4 ounce of oil, 4 ounces of spinach.
GFD: I mix and eat
Prep: I calculate, weigh, measure, cook, record, eat.
I'm done, By the way. GFD is complicated for you and that is fine. OP can make his own mind. Besides, it's really is not a bad starting point.
