Yeah, it's a LOT! I only started CC about a week back to keep a lid on my stress eating, and I'm managing to combine it with IE through some kind of nutso alchemy, but no way in the world would I give up my olive oil! I'm eating some right now actually that I used to marinate my lamb chops. One thing I learned when I started IE is that healthy fats don't actually make me fat... They just stop me getting hungry!
I think it's like buying expensive foundation... Go bargain basement on some things, sure, but others are well worth paying significantly extra calories for. And a ludicrously tasty, healthy appetite suppressant is one of those things!
If you're not that fussed about olive oil, but you want to spend big on something else, it might be worth it
