SNAQ
This project has been concluded in January 2023.
Scientific Report
The SNAQ Project (Adherence of Reporting Energy Intake by a Novel Food Photo Recognition Dietary Assessment App on Morbid Obese Subjects Scheduled for Bariatric Surgery), initiated by Prof. Marco Bueter in 2019 and concluded in 2023, explored explores how Roux-en-Y Gastric Bypass (RYGB) influences food selection, total energy intake, and meal patterns in obese women. Using photographic food recognition (PFR) with the mobile application SNAQ, this study directly measures dietary intake in a real-life setting, overcoming some limitations of self-reported dietary tracking.
This research provides the first direct and validated measurement of dietary intake in RYGB patients, offering valuable insights for optimizing post-bariatric nutritional counseling. Although SNAQ appears to be a reliable tool for assessing daily energy intake, future research is necessary to address its limitations, such as underestimation and wide limits of agreement. Additionally, the clinical relevance of SNAQ should be further explored in different populations.
The study was approved by the Ethics Committee of Zurich with BASEC-Nr. 2019-00952.
The study is registered on ClinicalTrials.gov with ID NCT04600596 (ClinicalTrials.gov).
