Obesity

In hundreds of studies around the world, scientists were creating obese mice and rats to use in diet or diabetes test studies. No strain of rat or mice is naturally obese, so scientists have to create them. They make these creatures morbidly obese by injecting them with MSG when they are first born.

The MSG triples the amount of insulin the pancreas creates, causing rats (and perhaps humans) to become obese. They even have a name for the fat rodents they create: “MSG-Treated Rats.” (See MSG and Weight Loss)
