You cannot, in any way, say that these two scenarios are equal from this study alone.  While the study tested insulin resistance after 1 night of sleep deprivation and in a separate of animals after 6 months of a high fat diet, they are only point in time measurements.  How quickly does the body rebound from the sleep deprived drop?  After 1 good sleep?  After a week?  How long does the resistance last after eating a high fat diet for 6 months?  After 1 meal?  After a week?  After 6 more months?  Does 1 night of sleep deprived night lead to the same number of dogs developing diabetes as those fed the diet for 6 months?  So much sensationalizing...
