 :::PPdd - in fact, if a study could demonstrate statistically that weight reduction and exercise + meditation significantly reduced the risk of heart disease over weight reduction and exercise alone, that would be both scientifically meaningful and interesting.  Occam's razor is a principle of selection - it says that we should select the simplest explanation that accommodates all the available evidence. if available evidence were to show that meditation had a measurable impact on incidence of heart disease, then Occam's Razor would suggest that the standard medical model would have to be rejected or revised, since it would no longer adequately accommodate the evidence. 

 :::In other words, one needs to show that the study itself is flawed; one can't simply assume that that the study is flawed because the study's presumptions conflict with conventional models.  doing so would be unscientific.  "
