While the fitness community has already empirically identified that diet is 90% of success

Are there any papers / data-sets that demonstrate this? If so, could you share here or at my email (see profile)? Would be greatly appreciated it. It's been my hunch this is true, but haven't seen the evidence for it.

Hang out at /r/fitness, and tons of references will be thrown at you over time with even more advocating one or another nuance. The results in progress/achievement posts quite consistently emphasize that if you don't pay attention to the diet, you'll quickly wreck any gains you sweat out in your workouts. People are only too happy to cite research papers in discussions when asked, but I have yet to see a study so overwhelmingly conclusive that even the food, medical, pharma and exercise industries will concede the point.
