This project was submitted to the Transforming Health and Care Systems (THCS) call under Horizon Europe. The aim of this call is to strengthen sustainable, people‑centred and innovative health systems through prevention, digital solutions, and care. The Carlos III Health Institute (ISCIII) is acting as the funding agency, and is prioritising collaboration between Health Research Institutes (IIS) and primary care, as strengthening primary care is a central objective of the call.

The project is coordinated by Prof. Peter Weijs of the Amsterdam University of Applied Sciences, and involves collaboration with partners from five other countries, including two Spanish institutions: IRYCIS and IDIPAZ. Dr Victoria Castell, a primary care physician and researcher affiliated with IDIPAZ who works at the Primary Care Centre Doctor Castroviejo will contribute clinical expertise and insight from her experience in everyday primary care practice, and will recruit participants for the clinical trial. IRYCIS's activities are is led by Dr Alfonso Cruz-Jentoft, Head of the Geriatrics Department and the Geriatrics Group (IRYCIS Area 5). He is an internationally recognised leader in the fields of sarcopenia and geriatric nutrition. His team also includes Dr Beatriz Montero-Errasquín, who is actively collaborating on the project. SONETTO builds on the successful SO-NUTS project, in which a digital personalised intervention optimizing nutrition and physical activity behaviour was developed. The project also involves the European Federation of the Associations of Dietitians and the European Association for the Study of Obesity.
