What works for obesity

To halt the obesity epidemic, interventions that are focused on individuals, such as lifestyle changes and prescribed drugs, are not sufficiently effective; the focus needs to shift to public health interventions. It is ironic, says Jain on p 1387, that although most experts agree that the obesity epidemic is primarily environmental, research has so far been ignoring this factor. This clinical review summarises the evidence for prevention and treatment of obesity, discusses the strengths and weaknesses of current research, and proposes a five part strategy for achieving an evidence based public health approach to the obesity epidemic.
