Weight loss drugs could help end obesity – but risks remain, WHO says

A new class of weight loss drugs developed by Novo Nordisk and Eli Lilly “opens the possibility of an end to the obesity pandemic” alongside other interventions, the World Health Organisation (WHO) said this week. But the global health agency said it has concerns that unless health systems prepare properly, the drugs could distort the response to the global obesity crisis, risking leaving people behind and overshadowing other steps to improve health. The new drugs “have the potential to be transformative”, according to the WHO’s chief scientist, Jeremy Farrar, its director of nutrition, Francesco Branca, and his senior adviser, Francesca Celleti, in an opinion piece in the Journal of the American Medical Association (JAMA). The article is the agency’s clearest comment yet on the potential of the new drugs, known as GLP-1 receptor agonists. But “medication in isolation will not be enough to address the obesity crisis,” they added, calling instead for the innovation to push clinicians, governments, the pharmaceutical industry and the public towards considering the condition a chronic disease that needs further study into how best to prevent and treat it.
