  • COVID-19 and impact on peer review

    As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times.  Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.

  • Consensus Statement

    Obesity is a complex medical condition and is influenced by several factors. Most of them are biological, beyond full personal control. The media, public, and even healthcare providers, including doctors, focus overwhelmingly on the contribution of individual choices and responsibility. We need to sum all efforts to eliminate weight stigmatization.
