The authors of a scientific paper touted by Dr. Mehmet Oz have retracted their work that said green coffee beans could support weight loss. Joe Vinson and Bryan Burnham were sponsored by Texas-based Applied Food Science Inc. to write about the weight-loss benefits of green coffee extract. Their work was touted on The Dr. Oz Show, and Dr. Oz was later grilled by the Senate Subcommittee on Consumer Protection for promoting it. In September, AFS paid $3.5 million to settle an Federal Trade Commission complaint that the âstudy was so hopelessly flawed that no reliable conclusions could be drawn from it.â
