What kind of Coconut Oil yeilds the most benefits?

Hello,

I am doing low carb and intermittent fasting. I have heard of the benefits of coconut oil and wanted to try it. Now my store only had Spectrum Expeller Pressed Organic Coconut Oil Refined. Which one should I try? Refined or Unrefined? Expeller or cold pressed? Virgin or not? So many choices. Thanks for your help.
