Also agree with the guys. In the grand scheme of things, it's a refinement that may make a diff to elite bodybuilders but won't account for 99% of results.
I'll qualify that by saying that, in some cases, it may have a more significant impact ... in the case of people who are insulin resistant or have diabetes.
Otherwise, if your insulin related processes are working just fine, it's a 1% deal mostly.
But that 1% might give an elite athlete the edge. For the rest of us, well ...
