Fat portion in relation to protein content?

[InkblotJo]

So... I'm tentatively considering attemtping a Whole 30, as daunting as it seems. I just finished reading It Starts With Food (in a single sitting, oops, there goes my afternoon!) and I really appreciated the simple guide to mealplanning . I'm a very lazy and inexperienced cook, so I'm sure any meals I make on my Whole 30 will be... limited in technique. At any rate, I was wondering about the fat and protein size guidelines. The book says to use the size of your thumb as a gauge for fat portions at each meal. But does this change according ot the fat content of your protein? For example, if you were to have chicken breast, would you add more supplementary fat than if you had, say, a fatty cut of steak? Or am I overthinking things?

Thanks!

You're thinking like an experienced cook! You really would bump the fat up with a chicken breast and reduce it with a ribeye steak.
