The obesity epidemic is a major public health concern with a significant economic burden in the USA. Bariatric surgery is the most effective and durable weight loss treatment, with long-term cardiometabolic health benefits. Among different types of bariatric procedures, sleeve gastrectomy (SG) has become the most commonly performed in USA. While SG is expected to result in a 50-60% excess weight loss, inter-individual differences in weight loss are large and approximately 25% of patients can be considered poor weight-loss responders who either do not lose a substantial amount of weight or regain the lost weight afterwards. The mechanisms underlying this clinical variation remain unknown and interventions to improve on these outcomes critically lacking. Of interest, altered daily dietary habits are experienced by a substantial proportion of bariatric surgery candidates, raising the question whether such alterations may contribute to inter-individual differences in weight loss success. Therefore, the purpose of the study is to compare dietary habits after bariatric surgery in patients with poor weight loss versus good weight loss outcomes.
