My credence that that is the case is much higher than that lithium is a major cause of the obesity epidemic. I wouldn’t be too surprised if contaminants explained ~5-10% of the weight that Americans have gained since the early 20th century.
The arguments for contaminants that seemed most appealing to me at first (lab and wild animals getting fatter) turned out to be really dubious (as I briefly touch upon in the post), which is why I’m not more bullish on it.
