Summary: Although bariatric surgery leads to significant long-term weight loss, weight gain after surgery affects a considerable percentage of patients. Additionally, some patients experience inadequate weight loss. The effectiveness of anti-obesity medications for post-operative weight gain has not been firmly established yet due to varying study populations and designs. Observational studies consistently show the benefits of medical weight management after bariatric surgery, particularly with liraglutide, topiramate, and phentermine/topiramate, while new anti-obesity medications are expected to be helpful for post-surgical weight optimization.

Summary: This study found substantial variability in the percent total weight loss following bariatric surgery, with functional brain imaging showing more variance in post-surgical weight loss than psychological or metabolic information. The neuronal responses during anticipatory cues and receipt of drops of milkshake differed between individuals with severe obesity and healthy-weight controls, with changes in brain response related to a composite health index. Despite no correlation with post-surgical weight loss in the entire surgical group, participants who underwent Roux-en-Y gastric bypass (RYGB) showed predictive power in several regions and contrasts.

Summary: This systematic review examined the relationship between macronutrient intake and weight loss after bariatric surgery (BS). Eight articles involving 2,378 subjects were included, and the results indicated that protein intake was positively associated with weight loss after BS. Prioritizing protein followed by carbohydrates and reducing lipid intake favored weight loss and weight stability after BS. The review suggests that a high-protein diet (>60 g to 90 g/day) may be beneficial for weight loss and maintenance after BS, but a balance of other macronutrients is also important.

Summary: There are various factors, both biological and behavioral, that contribute to the individual variability in weight loss response. These factors include eating behavior, societal norms, psychological and personal factors, and major life events. Future research should consider assessing these factors to better understand the underlying reasons for the variability in weight loss therapy.

Summary: This study aimed to evaluate the basic taste identification, induced perception, and pleasantness in normal-weight controls and obese subjects before and after bariatric surgery. The findings revealed that the perception of basic tastes is similar in normal-weight and severely obese subjects. Sleeve-gastrectomy-induced weight loss significantly increases basic taste-induced intensity, and selectively reduces bitter-related pleasantness without affecting the ability to identify the tastes.

Summary: The study found that bariatric surgery led to improvements in patients' BMI, depression, and food cravings, as well as quality of life, body image satisfaction, and self-efficacy for exercise. Higher levels of self-compassion were associated with better psychological outcomes, such as lower post-operative depression and higher quality of life, but not with post-operative BMI or food cravings. Further research on the long-term effects of self-compassion on health outcomes post-bariatric surgery is recommended.

Summary: The lack of standardization in measuring patient-reported outcomes (PROs) and PRO measures (PROMs) has led to the quality of life being underrepresented in obesity treatment research. The S.Q.O.T. initiative aims to standardize the measurement of quality of life in obesity treatment, and the first consensus meeting brought together experts and patients to identify key PROs and preferred PROMs. This meeting provided a first step towards standardizing PROs and PROMs in obesity treatment research.

Summary: Obesity is a complex chronic disease with various factors, and it is associated with multiple complications. The treatment for non-pregnant adults with obesity should be determined based on their body indices (body mass index (BMI) and waist circumference) and the presence and severity of obesity-related complications. Supervised lifestyle interventions, such as reduced or low energy diet, very low energy diet (VLED), or pharmacotherapy, should be the focus for individuals with BMI 30-40 kg/m2 or abdominal obesity without complications, aiming for a weight loss of 10-15%. For individuals with BMI 30-40 kg/m2 or abdominal obesity and complications, or those with BMI > 40 kg/m2, a weight loss target of 10-15% body weight is recommended, and more intensive interventions like VLED, pharmacotherapy, or bariatric surgery may be required, potentially in combination. Those with BMI > 40 kg/m2 and complications should aim for a weight loss target of > 15% and be referred to specialist care, which may involve VLED with or without pharmacotherapy and bariatric surgery.

Summary: This study explored the effects of dietary weight loss intervention, with and without exercise, on health-related quality of life, depressive symptoms, and anxiety in premenopausal women. The results showed that the addition of exercise to energy restriction had a significant positive impact on health-related quality of life, depressive symptoms, and state and trait anxiety scores. Exercise can improve mental health and quality of life in women with severe obesity without further weight loss.

Summary: Self-reported dietary intake is prone to errors due to memory-based reports. This study used a repeated-events framework to examine these errors and found that self-nominated day reports were more accurate than experimenter-nominated day reports. Participants often made errors by reporting a food from the wrong day rather than by omitting foods not recorded in the diary. Surprisingly, accuracy varied based on the days of the week and study completion year. Overall, these findings contribute to a better understanding of dietary self-reporting.
