I tried coconut oil for a few weeks once. Gave me an extreme case of lethargy and foggy-headedness each time I took it though. Apparently this was due to something known as "candida die-off", since my intestines were supposedly overrun with candida bacteria that give off strange toxins when they're killed by the coconut oil. Also gave me the runs. :P So I gave it up after a few weeks and felt normal again.
Now I just drink a truckload of milk a day to get my saturated fats in. lol
