Gut bacteria and overeating

"Researchers in Shanghai studied mice who had been bred to be resistant to obesity. These mice remained slim despite being fed a rich diet and being kept from exercising. However, when some of these mice were injected with the human bacterium enterobacter, they quickly became obese.

Enterobacter was first linked with obesity after being found in high quantities in the gut of a morbidly obese human volunteer, said the report from Shanghai's Jiaotong University.

The mice were injected with the bacterium for up to 10 weeks as part of the experiment.

The experiments show that the bacterium 'may causatively contribute to the development of obesity' in humans, according to the paper published in the International Society for Microbial Ecology."

Anecdotally, a couple of humans loss weight on specific diets that did not feed the bacteria, but there was no total energy input available. So did they lose weight because they ate less by willpower, or limited menu, or because of not feeding bacteria?  

Wiki :

Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Several strains of these bacteria are pathogenic and cause opportunistic infections in immunocompromised (usually hospitalized) hosts and in those who are on mechanical ventilation. The urinary and respiratory tracts are the most common sites of infection. The genus Enterobacter is a member of the coliform group of bacteria. It does not belong to the fecal coliforms (or thermotolerant coliforms) group of bacteria, unlike Escherichia coli, because it is incapable of growth at 44.5 °C in the presence of bile salts. Some of them showed quorum sensing properties as reported before [1][2]

So it should not be in the gut anyway, so WTF. More useless information with respect to obesity.

Ultimately, the question becomes if one is able to remove all carbohydrates with a caloric density of say 0.2 K/gm, can I adhere to the eating plan long term and lose weight? It is the adherence that is the problem, along with overeating of meat.

Enough. add picture:
