Intelligent people recognize more than one thing can be true at the same time.
Obesity is not caused by low IQ. Again, I'm forced to repeat the obvious. Hundreds of requests have been posted on MESO by members desperate to increase their appetite, because they find it PHYSICALLY IMPOSSIBLE TO EAT ENOUGH TO GAIN THE WEIGHT THEY WANT. That's the most direct, simplest evidence I can present to the doubters that calorie intake is heavily regulated by the brain and body. Willpower only goes so far, or you must believe 500 pounders have more willpower than the guys who can't gain weight without a drug that increases appetite at a biological level.
Obesity does cause severe inflammation, caused by endotoxins leaking from the digestive tract, which harms cognition and ultimately lowers IQ. So there is a basis for "fat and stupid".
Incidentally, endotoxins are almost certainly present in large amounts in UGL gear as well, but no one tests for it, even though Jano offers it, and suggesting steps be taken, just like pharma does, to neutralize them gets scoffed at by homebrewers as being absurd, "I can't feel no endotoxins you dummy! derp derp". But I digress.
There's another stereotype, about the musclebound idiot, and just like the one above, there's a basis for it.
High levels of testosterone, particularly supra-physiological levels from AAS use reduce cognition too,
"Anabolic-androgenic steroids (AAS) are used to improve physical performance and appearance, but have been associated with deficits in social cognitive functioning. Approximately 30% of people who use AAS develop a dependence, increasing the risk for undesired effects.".

Luckily both are reversible.
Soon GLP drugs and their even more effective successors will be accessible to everyone. At that point, obesity will become truly optional, and failing to use those tools to protect one's health will be a genuine indicator of stupidity, just like those foolish enough to cruise on very high levels of steroids by calling it TRT+ or whatever, knocking down their IQ and damaging their health over the long term are the real idiots, vs the intelligent bodybuilder who uses high levels of AAS carefully, and intermittently,
