Hi Maith, In my opinion this research falls into the category of “one of Seth’s crackpot ideas that is easy and harmless to try.” I use the word crackpot advisedly; that is, with love and respect. In the past I’ve tracked “episodes of urgent hunger” because, like many others, I’ve had a tendency to raid the pantry. Since I’m aware of this subjective phenomenon, I thought it would be interesting to use it’s “surprising non-occurrence” as a target. So far I’ve attempted to have morning oil on 8 days, succeeded on 7. I had 4 days of surprising “no hunger” episodes (the first 4). I missed the oil on day 3. I haven’t had any surprising “no hunger” days since.
My subjective experience so far is that there’s no effect on how I feel except for a slight stomach upset at the start that might have affected my appetite. But I’m going to keep doing it for a couple of months and just see what happens. Seth’s theory is explained in his book The Shangri-La Diet.
I don’t think it is taken very seriously by nutritionists. The question of whether we should take nutritionists seriously remains somewhat open, however.
