I don't need a "double blind study" to prove anything. The proof is in the pudding, obviously an improved diet , including quitting gluten to maximize absorption is part of the process is a factor.<quoted text>
The DM II probably did all they could to reverse the condition up and including taking chromum (which reduces the food cravings) and a healthier diet.
Unless your's is a double blind study with a large enough group to be statistically significant you can't proof it was just these two substances that worked the change.
MDI and II are genetically very complex, so those aware of that will simply not buy into the supplement hype.
I compare it to a docter stating a lack of kalium (potassium) but not giving this (dangerous) substance but rather taking the systemic route as in remedying the ultimate cause, as the safer and durable route.
Once you see this work time after time there is no need to consult your silly studies.
There is no money in curing, MD's are never interested.
