The study, published online Thursday by the journal Science, is “pretty striking,” said Dr.Jeffrey S. Flier, an obesity researcher and the dean of the Harvard Medical School, who was not involved with the study. “It’s a very powerful set of experiments.”
Michael Fischbach of the University of California, San Francisco, who also was not involved with the study, called it “the clearest evidence to date that gut bacteria can help cause obesity.”
“I’m very excited about this,” he added, saying the next step will be to try using gut bacteria to treat obesity by transplanting feces from thin people.
