I hadn't seen that diet blog from Ara but I was just debating the need for high fat intake with somebody on FB the other day and told them Doc did believe we need high fat. That link you posted is pretty much what he has told me in our many conversations and I wish I had that to have linked earlier in terms week when I was debating the need for high fat in our diets.
Regarding your diet well to quote Braveheart, yer fooked laddie! (obviously lassie in your case). 
Knowing you I am sure you will figure it out.
