I honestly wonder how many of these types of studies aren't taking into account the other variables. Such as, low cardiorespiratory fitness leading to depression, or poor diet which obviously leads to diabetes, which means depression obviously can lead to diabetes. How much is causation versus correlation? The entire article goes beats around the bush until it finally admits, "And while a direct cause was not found for diabetes causing depression, experts still believe that the burden of living with type 2 diabetes may be a factor in developing depression." Basically all this research found was the people with obesity likely have depression and 37% of people with obesity have diabetes. The title is complete click-bait.
