5:2 is WORKING for me and all these people who are eating the quite normal, though perhaps not exactly balanced or healthy diet, that we subject ourselves to, because it allows us to have a little failure now and again, but then we just fast the next day instead. EASY, don't you think?
I sincerely hope so, it is certainly easier than most of the other stuff. That being said, knowing more about what you put in your body is not such a bad idea, given that dietary composition has effect on several major diseases.
And I think you illustrate another point - you have been through the whole gamut of diets. You say some worked, but still you are here - doesn't that mean that they are not working in the long run? If yes, you are by no means alone in that. As many studies have shown, long term results are bad for most diets, the vast majority relapses.
So selling or promoting this diet, with no data on long-term sustainability (at least 2 years), and no data at all on what it does to food choices, would be highly unprofessional and unscientific of the scientific community. (What if they had done that with Atkins?)
It is all over the media, so no worries that the public is not aware of this. But the medical and scientific community should not make an exception for this diet based on the data so far.
