Study suggests microbiome could be key to losing weight

A new study out of Seattle shows that what's in your gut -- specifically the microbiome -- could have an impact on your ability to lose weight.

The scientists tracked the baseline microbiome of 105 people who were trying to lose weight and found that despite the entire group implementing healthier diet changes, roughly half of them did not lose weight. In looking at the participants' baseline gut microbiome, the researchers discovered that the people whose bodies were resistant to weight loss had microbiome with lower bacterial growth rates than their now-thinner counterparts.

What the ISB study ultimately determined was that there are some people who do not lose weight simply due to diet changes, and that those folks likely need greater interventions than just switching up what they eat.
