Coconut oil has the highest proportion of MCT's (medium chain triglycerides) of any oil. Although saturated, it is of the shorter chain variety and therefore much easier to burn. It also, being saturated, is not prone to unwanted oxidation and this is a good thing. Ghee also has high quantities of MCT's. It must be recognized that all saturated fats are not the same. The short and medium chain saturated fatty acids are extremely advantageous.
