We are delighted to announce that in 2016 the congresses of EASO (ECO2016) and the IFSO European Chapter (2016 IFSO-EC Annual Congress) will merge to create the inaugural European Obesity Summit. We have done this in order to bring together colleagues from every area of obesity research, prevention and management. We will develop parallel programmes and joint sessions to ensure that delegates are given the opportunity to increase their knowledge and network with a diverse range of colleagues. We look forward to welcoming you to Gothenburg, Sweden from 1st to 4th June 2016.
