If your guru's ideas have an expiration date, maybe it's time to find one whose ideas have a longer shelf life.

Have you just stumbled upon an old book, blog post, interview, etc. from your favorite guru only to have someone exclaim how old that is and how your guru's opinions have changed?  It might be time for a new guru.

Quick background here.  First, no I haven't dropped the Paleo ApprovED issue, but there are some things related and lots of stuff unrelated going on that have eaten up time and energy to blog on the subject.  It is a sensitive issue and needs more "care" than your run of the mill blogging.  It is also rather stressful and defeats one of the purposes of this blog as an outlet for my sarcastic side -- for which a post such as this is perfectamundo!    So that said, as I was looking for a post on Robb Wolf's blog (this one) my search also popped up the following post:

Insulin: Anorexic?

Does Coconut Oil stimulate appetite?

A comment I read on PaleoHacks led me to this article on Livestrong:  Does Coconut Oil increase your appetite?  It cites the following study: Ingested Medium-Chain Fatty Acids Are Directly Utilized for the Acyl Modification of Ghrelin .

ABSTRACT:

Ghrelin, an acylated brain and gut peptide, is primarily produced by endocrine cells of the gastric mucosa for secretion into the circulation. The major active form of ghrelin is a 28-amino-acid peptide containing an n-octanoyl modification at serine that is essential for activity. Studies have identified multiple physiological functions for ghrelin, including GH release, appetite stimulation, and metabolic fuel preference. Until now, there has not been any report detailing the mechanism of ghrelin acyl modification. Here we report that ingestion of either medium-chain fatty acids (MCFAs) or medium-chain triacylglycerols (MCTs) increased the stomach concentrations of acylated ghrelin without changing the total (acyl- and des-acyl-) ghrelin amounts.
