If you really hate going to the gym and can't fathom the thought of another diet, there may be an interesting (albeit unsavory) solution on the horizon.
A group of about 21 volunteers will pop pills that are "odorless, tasteless, double-encapsulated," lead researcher and assistant professor Elaine Yu told People magazine.
The capsule contents, which will be taken orally by the test subjects, will contain gut microbes from lean, metabolically healthy donors. The purpose of the study will be to test whether the microbes from thin people will have an impact on the bodies of people with obesity and/or insulin sensitivity.
All donors, said Yu, will be vetted and approved by the FDA.
"The donors go through a screening process that is more rigorous than what is required for blood donation," she said. "Donors must meet strict weight criteria and are screened for medical, infectious and metabolic disorders."
The trial is scheduled to begin in March. Researchers will follow participants as they take fecal pills (or cocoa powder-filled placebo capsules, according to U.S. News & World Report) for 12 weeks.
"Multiple lines of evidence suggest that gut microbiota play an important role in regulating human metabolism," the trial proposal explains. "Major study outcomes include change in weight, insulin sensitivity, and body composition."
