I started taking coconut oil in January, and am still using it. My body temperature has gone from 95.8 in the mornings to about 96.8. So in terms of improving my metabolism, it has helped somewhat. The weight started budging a little, but a couple of benefits that I did notice almost immediately were:
1. New hair regrowth.
2. Sleeping much better. Often would not sleep at all, and usually got no more than 4 or 5 hours per night.
3. My arthritis was noticeably improved.

I still take the coconut oil, because I feel that it is extremely beneficial in transporting the nutrients in your body. The coconut oil website contains much information about coconut oil being a medium chain fatty acid, vs a long chain fatty acid, as are most oils that we consume.

At the beginning of June, I started taking a new supplement and consequently I feel like I have discovered the fountain of youth. I am amazed at how great I feel, and how many improvements I have experienced with a lot of my symptoms.
