On: Pathogen from gut of obese human causes obesity in...

[not_that_noob]

tl;dr: fat guy lost a ton of weight by a diet that reduced a specific kind of gut bacteria; this bacteria inserted into mice engineered to be thin caused the mice to gain weight.

Ergo, bacteria may be driving obesity.

Not only obesity, but insulin resistance: basically gave the mice the start of "metabolic syndrome", as also observed in obese humans.

So in theory, if a pill was developed to just kill that bacteria, fat guy loses weight.

Maybe big pharma and the food industry knew this the whole time.
