Dr. Oz diet pill study, A study about the supposed weight loss benefits of green coffee bean extract contained unverified data and has been retracted.
The study -- published in the journal Diabetes, Metabolic Syndrome and Obesity -- was promoted on the Dr. Oz TV show and received national attention, CBS News reported.
However, the two researchers who were paid to write the study have admitted they could not verify the data, according to the science watchdog website Retraction Watch.
"The sponsors of the study cannot assure the validity of the data so we, Joe Vinson and Bryan Burnham, are retracting the paper," the researchers said in a statement, CBS News reported.
Their study claimed that green coffee bean extract pills could help people shed excess pounds without having to diet or exercise. Sales of the pills soared after Dr. Oz promoted them on a show in May 2012. CBS News reported.
