surgery (BS), especially procedures like Sleeve Gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), is the most effective treatment for obesity. Yet, the exact mechanisms governing its effect are somewhat elusive, with current research mainly focusing on post-operative food intake outcomes based on self-reported data, which might not fully capture the nuanced changes in eating behaviours.\n\nTo address these gaps, our study plans to employ the newly developed \"drinkometer\", a device capable of analysing the intricate changes in drinking behaviour following BS. This tool promises to bring a more detailed perspective to the changes in ingestive behaviours, bypassing the inaccuracies of self-reporting methods. By expanding our research to encompass diverse patient demographics and examining potential links to physiological shifts like gut hormone level alterations, the study aims to provide a more rounded understanding of the long-term impacts of BS on eating behaviours.",[114],"Obesity",[114,116,41,117,118],"Ingestive Behaviour","Gut Hormones","Drinkometer","2026-05-14",{"date":121,"type":122},"2026-05-18","ACTUAL",{"date":124,"type":122},"2024-02-13",{"date":126,"type":110},"2027-12-31",{"name":5,"class":6},2]
