I was asking for specifics, the mechanism.
I will give you an analogy, I have to fix things and trouble shoot in the lab all the time, clinical issues with patients, equipment, chemicals.
There is always the 'surface' answer, like 'the machine is broken' or 'the patient has a high potassium', but that is not always that helpful.
I have often gone back to basic biochemical pathways to figure out how to sort things out.
Because I know the premise of 'why' you can apply it to more scenarios than one.
Bodybuilding is very similar, it is applied biochemistry and physiology, and then you experiment to see how your body responds to it, what works, what doesn't work.
Taking in dextrose/glucose/sucrose post workout may not be the best way to trigger protein synthesis in all people, it may actually make some people put on more fat.
That is why I would prefer a more elaborate description, people know how it works, then they can see if it would apply to them.
