Yes, there are several books out there on good vs bad fats.
I believe it all except that I don't think saturated fats are bad.
I avoid trans and hydrog that's it. Get my EFAs everyday!

The Fat Panic for me isn't as much guilt as it is FEAR...it's like there's 2 brains in my head. My old low-nonfat living brain and my new (4 years new now) low carb brain!

You'd think I'd be over it! I usually end my Fat Panic with the thought,

"Well if eating low carb really WOULD make me fat, I'd be FAT RIGHT NOW, and I'm NOT. So there!"

Then I just spin on my heals and put that extra butter on my plate! I don't even flinch about it.
