Well, I don't think my great grandfather, who lived to be over 100, had AA in his cells, and he went bald very young, but otherwise was in great shape, with very few problems.  His eyesight was not great as he got really old, but he could still see.  And he could get around without problems.  "Latent viruses" will reactivate with stress, and as you get old you lose the "youth associated hormones," but also there is more of a chance you will be deficient in one or more vitamins/minerals.

I have read something that might apply to getting AA out of the cells more quickly.  In a book that talks about low carb dieting it said that elderly and sickly people should be careful to eat enough carbs so as to avoid too many PUFA's being brought out into the blood stream.  Eating low carb/high fat causes the body to begin to use stored body fat for energy.  The lower the amount of carbs in your diet the more fat will be used.  So I am assuming that this would apply to removing AA from the cells.  Correct me if I'm wrong.  I haven't as of yet read about AA in depth.  Also I have read that eating a lot of good quality saturated fat will allow your body to give up some of it's old toxic fat. 

The point I make about certain studies is that if you feed animals raised on something like corn oil only coconut oil as their fat source, the omega 6 PUFAs will be replaced, and during this process, there may be higher levels of certain markers of oxidative stress.  This is why I advise an antioxidant-rich diet when switching to a very low PUFA diet.  I don't know if it's a particularly good idea to try to speed the process up, and the idea you suggest may be relative to the amount of overall calories consumed.  My guess is that if you try it but eat more calories than you need to, it might not work.  It may work for a lot of low-carb dieters because they tend to eat less calories than usual.  Just keep in mind, in the low-carb context, that something like lard, considered by most "experts" as a "saturated fat," is only 40% saturated, and so I would not consider eating it under any circumstances (except if starvation was at hand).  Uncooked butter, coconut, and palm kernel oil are the only fats I would use.  I don't mind eating cheese, because it is highly saturated, and dark chocolate has a high percentage of SFAs too.
