Ahh, statistics.  How do the 55% or 85% numbers compare with the population as a whole?  Is it a significant increase?  Is there evidence of a statistically significant correlation between obesity and being overweight?  Are there any factors that might be involved that are also correlated with obesity but that might be the true cause?<p>PS - Study recommends a ketogenic diet which I am very much in favor for.  It has done wonders for me (ymmv).  But I am still on the fence about being &quot;overweight&quot; being a direct cause of diabetes and not an effect.
