Every once in a while my budget requires grass-fed beef / chicken instead of free range. I usually eat grass fed and think there's a difference, but haven't "measured" anything. I DO agree with your compromise solution -- I do NOT eat the fat from this meat. Again, I'm fortunate to be able to occasionally get grass-fed fat trimmed from animals as they're butchered. I render that down for the "lean times." I also eat a lot of coconut oil, olive oil, avocado oil, etc.
