More on Evidence-based medicine


The thing I love about being the nerd gym is that after I post a rant about something I can be sure to wake up to a bunch of texts from Randy with more details. Today's was really good and I can't help but share it.

Rand found this article in the Mayo Clinic Proceedings about how we study overweight and obesity. It's a quick read about the terrible studies we base our evidence based medicine on. Statistical tricks to throw out data and more. It's a quick read. I loved Randy's summary of it:
Evidence based dietary advice is so bad because the evidence is so flawed. When examined more closely, fat and overweight people in the studies regularly under report food intake below what would be required to sustain life, much less obesity.
Think about that. Studies are trying to find evidence to support "eat less, move more" and in these studies people dramatically and consistently under report what they eat and they get fatter and sicker.  The input to the study are "people are eating less" the output (evidence) is that "people are still getting fatter". Yet the conclusions from the study - the evidence-based medicine - is that we should eat even less. There is no evidence supporting that, but it's the current group-think and you can't go against that.
