Up until a few weeks ago, I thought so. Then, I saw something on Durianrider's blog. He points out that essentially, eating olive oil is basically pouring pure fat into your body. While I don't completely agree with him about it being 'refined' (It's really as refined as fresh squeezed orange juice, if you think about it), I did think his assertion that it slows you down and makes you more sluggish and kinda just clogs up your system was an interesting one.. I honestly couldn't find a lot of information about it, but I decided to try cutting out olive oil anyhow, just to see if what he said held true.
Well, it's been a few weeks now since I've had olive oil. I find that I need to eat a lot more (makes sense, because I'm not eating all the extra calories from the fat, but other than that - I feel so much more energetic and awake, and just generally more alive. I don't know why this is, and I haven't found any research supporting this really. But I haven't felt the need to add it back to my diet yet, so, though I'm not entirely sure yet, I do think I plan upon removing olive oil permanently from my diet...and I invite anyone else who might be inclined to give this a shot as well.
