Not sure where else to put this:
Admitting that a single study is not likely to ever be completely conclusive, I was thinking something like this might be optimal to help eliminate a lot of controversy and denials on all sides whenever diets are compared and settle at least a lot of questions within a reasonable degree, or at least forward the conversation significantly.
So, why not get a bunch of the experts on the divergent diet ideas together to themselves design and check on a diet plan for a randomized trial of say a thousand people divided into the different groups (after much data is taken on each group and individual for things like current health markers, body fat %, levels of various biomarkers, etc), and see how things go?
Iâm thinking perhaps Volek and Phinney and maybe some others design a nutritional ketogenic diet, McDougal or whoever is big in the starch crowd today for theirs, some paleo people, whatever else is out there, etc. Maybe have at least 5 or 6 variants to divide a thousand people among or something. While I know there are a million different diets under the sun, a lot are not significantly different in meaningful ways, so Iâd think you could come up with a reasonable set that most would agree on as major competing diets to consider and agree on the reasonable people in the respective fields to design the diets for each.
That way, it canât be complained later âwell, that research didnât do my version of the diet right for such and such a reason, or they overlooked this or that, etcâ.
Unfortunately, I think the closest we get to something like this are game shows like âThe Biggest Loserâ and âMy Diet is Better than Yoursâ, which donât really take that many types of people, have a clinical structure, nor more get enough data points for each set (typically they are n=1).
With that in mind, what other considerations would you guys think would be needed here? What details are important? Beyond the expense and ulterior motives, is there some reason this kind of approach doesnât make sense?
