Do fat taxes work? Rely on the evidence not expert opinion

The Indian state of Kerala has introduced a fat tax on fast food in a bid to tackle obesity. A BBC report of the story included an expert who claimed both that the tax wonít work and that the government should run information campaigns instead to tell people that fast food is bad for them. In our new Campbell blog, Howard White argues that a review of the evidence shows that increasing the price of fast food can help to reduce demand. Further, a systematic review of interventions to promote healthy eating found no evidence of sustained benefits from information-based approaches. Itís time to rely on evidence, not opinions.
