The fats in coconut are good for energy and lauric acid gets turned to monolaurin so it has some utility. The problems I can see are that they can really only be used for energy and don't serve all of the important functions of palmitic acid so I think that it is better to have a combination of good animal fats and coconut. Also I dislike using too much food without micronutrients. It expends nutrients to digest and metabolize without replenishing nutrients. I get about 300 calories a day from coconut but couldn't see any more being desirable. It's definitely a good thing to include but a more varied approach is probably better.
Also I seem to have troubles with dessicated coconut that isn't ground up to powder. Coconut chips might be better properly chewed but I haven't tried them.
