Obesity is a serious health issue. In the UK the prevalence of obesity has trebled in the last 20 years and today one in five adults is clinically obese. ⋯ This finding implies that the efficacy of public health messages to individuals to inform their lifestyle choices will be enhanced by environmental changes that support and facilitate healthy options. The present paper focuses on the importance of communicating scientific knowledge to the stakeholders with a responsibility for tackling obesity and addresses some of the barriers that are encountered.
