WIN: a Feasibility Study of a Weight-Neutral Health Intervention

The WIN intervention aims to improve the mental, social and physical health as well as quality of life of participants with BMI≥30 without focusing on their weight, and with no aim of weight loss. The WIN 6 months intervention is based on the principles and methods of the weight neutral movement Health at Every Size (HAES). The content is developed in a co-design process that involved Danish participants who have lived or professional experiences with such approaches. The intervention uses the method of intuitive eating to align eating behaviours with internal cues of hunger and fullness rather than rules, restrictions and external cues. The intervention also draws on components from Acceptance and Commitment Therapy (ACT) to manage body image concerns and weight stigma.
