Yeah, I dislike studies because they mean nothing for the individual. You guys have probably never worked with a real client. Hand them a logbook, track their responses to everything, and watch them get results. Give them some basic dietary guidelines and watch their anecdotal success.
I'll leave it to you guys to sit around with "impressive" studies bending them to whatever conclusion you want. Are studies interesting? Yes. Should a lot of them be taken with a grain of salt? Yes.
Again, correlation does not prove causation. Somehow that keeps getting ignored.
This is a reason why I made the thread asking who on this forum works in the industry and in what fashion. For example, I've watched people gain a lot from vitamin D, but I had them get it from the sun or short sessions in tanning beds.
