Correlation =/= causation. So many leaps are being made here.
> One study of 60 healthy young adults (in their 20s and 30s) found that the fatter members of the group had significantly lower gray-matter densities in several brain regions, including those involved in the perception of taste and the regulation of eating behavior.
Maybe the lower gray-matter density, particularly in the "perception of taste and the regulation of eating behavior" areas, predisposes them to being overweight, rather than the extra weight causing brain shrinkage. You'd have to do a longitudinal study to be able to make a case for causation...
- ottbot 16y agoJust want to add that I much prefer "=/=" rather than "!=" when expressing an inequality.. I don't like the latter used in this context. I might totally wrong here, but I always something like "correlation != causation" as a test, not a statement - it could be true or false!
- izendejas 16y agoYea, the conclusion is overly simplified here. I think it's safe to say not exercising and not eating well is generally bad for your entire well being, not just your brain and weight.
