This study was aimed to describe nutritional and lifestyle parameters following One Anastomosis Gastric Bypass (OAGB). A multicenter study Two cross-sectional studies among OAGB patients across Israel (n=277) and Portugal (n=111) were was performed. Patients were approached ac-cording to the time elapsed since surgery. An online survey with information regarding de-mographics, anthropometrics, and nutritional and lifestyle aspects was administered in both countries simultaneously. Respondents from Israel (pre-surgery age of 41.6±11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6±12.3 years, 79.3% females) reported changes in their appetite (≤94.0% and ≤94.6%), changes in their taste (≤51.0 and ≤51.4%), and intolerance to specific foods (i.e., red meat, pasta, bread, and rice). Bariatric surgery-related eating recommendations were generally well followed, but a trend toward lower adherence was evident in groups with longer time elapsed since surgery in both countries. Most respondents from Israel and Portugal reported participation in follow-up meetings with a surgeon (≤94.0% and 100%) and a dietitian (≤92.6% and ≤100%), while much far fewer reported participation in any follow-up meeting with a psychologist/social worker (≤37.9% and ≤56.1%). Patients following OAGB might experience changes in appetite, taste, and intolerance for specific foods. Adherence to bariatric surgery-related eating recommendations is not always satisfying, especially in the longer-term post-surgery.
