For someone who is critical of food prescriptions, you say some kind things about the Mediterranean diet. 
Perhaps you are not aware of the NEJM study DIRECT. Which compared low fat, Mediterranean diet and ketogenic diet.
In virtually every realm of markers that matter in my opinion the Ketogenic diet outperformed the others. Lower triglycerides, higher HDL, lower Creactive protein, smaller waists, lower weights. Lower HemoglobinA1c .  
And for a diet that can't be adhered too, this was a 2 year study. Sorry the low fat diet high carb diet was the poorest choice.
Are you sure you have the level of understanding to be critical of this way of  eating for life?
