> And if in your small town everybody is obese, before to blame everybody for eating too much, or being lazy couch potatos, look for chemicals in the drinking water, leading to a broken satiety system, causing people to eat huge amounts of food. This is why the right to have safe drinking water is so important.

I don't think there's any reason to assume that obesity is caused by any specific chemical found in some but not all drinking water, in such a way that explains differences in obesity rates. If that were the case we probably would've figured that out by now and would be systematically treating drinking water to remove that chemical.
