The idea that virgin olive oil was a good fat and easy to add to the diet, has been around for quite awhile. But it is always good to see studies that really support the idea.

I remember as a child, the grown ups around us were going on a strange diet, whereby people were losing weight by consuming several ounces of oil.
I recall, the major problem at that time was how to ingest the required amount. To date I have not found anyone who could remember that diet or what kind of oil was used.
There may have been additional requirements, such as omitting sugar and flour products, but I only remember the one requirement .

Wouldn't that be a big kicker if it turned out to be extra virgin oilive oil?
