It isn't a matter of deficiency... but rather one of efficiency.
Muscles become resistant to insulin... It is a known fact.
Causes vary.
Age-related declines may be correlated.
Chronic over-eating may be correlated.
Athletes act like they are immune to such, but gym warriors, like most of society, are at risk for insulin resistance... to varying degrees.
Why?
Chronic over-eating... low fiber intake.
Whatever the cause, it manifests.
GDAs mitigate this to some degree.
Vitamin E appears to mitigate insulin resistance related to oxidative stress.
So, again... it isn't a matter of deficiency... but, rather, one of efficiency.
