The study, by a team of researchers from Rutgers University, looked at how levels of the hormone affected laboratory mice. When GLP-1 was reduced in the mice, they over-ate and consumed more high-fat food. When researchers enhanced the signal, they were able to block the mice’s interest in fatty foods.
While it still needs to be established that the same effect happens in humans, there is already a drug on the market that scientists say mimics the hormone. Earlier this year, the Food and Drug Administration approved a Saxenda — a drug originally designed to improve glucose tolerance for diabetics — as a treatment for obesity.
