So I find the question underspecified, why do you want this?
Why are you decomposing body signalling without looking at the major sub-regulstort systems? If you want to predict sleep then cortisol, melatonin, etc. is something quite good and this will tell you about stress regulation which effects both endocrine as well as cortisol systems.
If you want to look at nutritional systems then GLP-1 activation is good for average food need whilst grelin is predictive of whether you will feel hungry at specific times.
If you’re looking at brain health then serotonin activation patterns can be really good to check but this is different from how the stomach uses it and it does have the majority of serotonin. But this is like way to simplified especially for the brain.
Different subsystems use the same molecules in different ways, waste not and all that so what are you looking for and why?
