The protocol you write about is drinking the Moreless drink and using a refractometer to buy food correct??? I'm sure you also have an idea of what is a balanced diet is.
I would think if you combine a refactometer with eating foods based on your metabolic type, this would be a winner.
It would be interesting to compare the results of a refractometer with the forms of muscle testing I use. I have even been playing with my own form of testing to see how powerful a food or drink is for me.
