I don't fear fats.
Omega 3s are just better fats than saturated fats (and you are really eating the Omega 3s - DG - with your choices, let's face it - else why go grass-fed?).
The other issue is protein. You need to make sure you are getting enough of this to retain/build muscle mass unless you want to look 'gaunt'.
So grass-fed beef ...OK. Grass-fed butter...good luck.
Not that anyone cares, but I try to maximize my protein while obtaining good fats (e.g. omega 3s).
For me, high protein/bad fat (e.g. burgers) is a bad combination as is low protein/good fat (e.g. grass-fed butter).
High protein/good fat (e.g. oily fish and, I concede, grass-fed beef) is just about on the money.
So why eat butter when you can eat salmon instead?
