In order to be accepted as anything other than an anecdote, you would require a much more rigorous study with a LOT more people and a much higher level of scrutiny. We would want to control for external issues, possibly genetic complications, gut flora, blood glucose levels, liver and pancreas health, illness, infection, cancers, etc...
Anecdotal evidence if fine for discussion, but no one should act upon it without medical supervision.
