Erzulie's right! Applesauce is the thing to use. I don't eliminate all the fat though, I just use very little. If you're using the jarred fruits, it's basically like a jam, so it's suggested to use 1/2 as much of the fruit as the amount of fat called for (so 1/2 cup of puree instead of 1 cup of oil).
I use the fruit and usually add 2 tablespoons of oil.
Some information I recently found:
New research is verifying that organic extra virgin coconut oil is the best oil for your health, weight managenment and has the potential to cure many of the ailments that have manifested in our bodies through having a highly refined diet.

it Coconut oil is the only natural source of beneficial Lauric acid other than human breast milk
it has a mild delicate flavor.
it is highly resistant to spoilage due to the antioxidant nature of the oil

Extra Virgin coconut oil is not the same as inferior Copra (or Cophra) oil which is produced under industrial conditions with high heat, requiring bleaching,deodorizing and refining to produce an edible product. Extra Virgin coconut oil (VCO) is produced under low heat conditions (< 27 degrees C) from fresh coconut, retaining a natural fragrance and taste. It also retains all the inherent qualities associated with its remarkable chemical makeup, qualifying it as the healthiest and most stable food oil on the market.
Coconut oils chemical structure remains intact and resistant to mutations when heated to high temperatures making it the safest oil to use for cooking. It has a long shelf life because it is so stable.
