has a wider collection of the literature and links to the recently published http://www.ncbi.nlm.nih.gov/pubmed/26287746 which finally establishes this as the causative snp and explains the method of action.

Thank you!

Except that the variations of the gene associated with obesity are also associated with eating a huge amount more:

Which is a much simpler explanation.

And even so, carriers of even the highest risk form of the gene are still on average only 6.6lbs heavier than normal:
