Obesity may be the result of excess hydrogen and methane gasses growling in the gut. Gas the culprit not over-eating or a lack of exercise say researchers at the Cedars-Sinai Hospital.
The hospital wants to make a fat-gas detector to help warn the future fat-assed porcine.
Chicken-egg phenomenon? Nothing was said about testing thin people. Still 792 people were studied for methane caused by the bacteria M. smithii.
Unless skinny breath is sampled allowing ten years for weight gain who's to say M. smithii is a cause and not a symptom?
Or is that question too obvious?
