“…The reduced intake of wholegrain products could be a reflection of food intolerances to bread, cereals, pasta and rice, 9,43–45 as well as prioritising protein intake over the consumption of grains to limit overall energy intake, as generally advised after BS. Together with the large decrease in the consumption of vegetables and wholegrains, dietary fibre intake in the present study decreased to 14.6 ± 5.2 g day –1 with only 10% reaching the recommended intake of 14 g per 1000 kcal 10 at 6 months post‐surgery, which is in accordance with low fibre intakes reported in previous research in the bariatric population 14,29,45–48 . Next to the general health benefits of dietary fibre, inadequate fibre intake in this population has also been linked to constipation, which is a common problem after BS 45,46 .…”

“…For example, short-term reductions in energy intake at 6 months post-surgery were associated with greater weight loss over 10 years in the Swedish Obese Subjects study. 15 This association is consistent with the research from Ostad et al 47 and Nymo et al, 21 who also reported better weight loss outcomes when intake of energy was lower. Additionally, attention should be paid to the qualitative aspects of the diet to optimise weight outcomes.…”

BackgroundBariatric surgery (BS) may result in inadequate nutrient intake and poor diet quality, which can lead to nutritional complications. The present study aimed to evaluate changes in macro‐ and micronutrient composition and diet quality in the first 6 months following BS.MethodsOne hundred seven participants undergoing BS (Roux‐en‐Y gastric bypass: n = 87, sleeve gastrectomy: n = 20) completed 3‐day food records before and 6 months after surgery. Changes in energy, macronutrient (carbohydrates, protein, fat, dietary fibre) and micronutrient intake (folate, vitamin B12, vitamin D, calcium, iron) were evaluated. Diet quality was assessed by adherence to the Dutch food‐based dietary guidelines.ResultsAfter BS, we observed a significant decrease in intake of energy and all macro‐ and micronutrients (p < 0.01 for all), except for calcium (−39.0 ± 404.6 mg; p = 0.32). Overall, nutrient composition slightly changed with an increase in the relative intake of protein (+1.1 ± 4.3 energy percentage [en%]; p = 0.01) and mono‐ and disaccharides (+4.2 ± 6.4 en%; p < 0.001) post‐surgery. Consumption (median [Q1, Q3]) of vegetables (−50 [−120, 6] g day–1), wholegrain products (−38 [−81, −8] g day–1), liquid fats (−5 [−13, 2] g day–1), red meat (−3 [−30, 4] g day–1), processed meat (−32 [−55, 13] g day–1), sodium (−0.7 [−1.1, −0.2] g day–1) and unhealthy food choices (−2.4 [−5.0, 0.6] serves week–1) significantly decreased after BS (p < 0.01 for all).ConclusionsOur results demonstrate both favourable and unfavourable changes in macro‐ and micronutrient composition and diet quality in the first 6 months following BS. Insight into these changes can improve dietary counselling in this population. Future research into underlying causes, consequences and long‐term changes in dietary intake is needed.

BackgroundObesity is a significant risk factor for osteoarthritis (OA). The most effective treatment for morbid obesity is bariatric surgery.PurposeTo study the effects of potential surgically induced weight loss on knee articular cartilage and OA symptoms of obese patients over a 12‐month follow‐up.Study TypeProspective longitudinal cohort study.Subjects45 obese patients (38 female, BMI = 42.3 ± 6.5 kg/m2) who underwent gastric bypass (intervention group), and 46 age‐matched conservative‐care controls (37 female, BMI = 39.8 ± 4.6 kg/m2).Field Strength/SequenceMultiecho spin echo sequence at 3 T.AssessmentKnee cartilage T2 measurements and WOMAC Indices were measured presurgery and after 12 months. The intervention group was split into successful (≥20% total weight loss (TWL)) and unsuccessful (<20% TWL) weight loss groups. T2 and WOMAC indices were also measured in controls at baseline and after 12 months. Changes among the three groups were analyzed.Statistical TestsAnalysis of variance (significance level 0.05).ResultsTwenty‐six (58%) intervention patients achieved ≥20% TWL. The <20% TWL group demonstrated significantly more T2 reduction in the deep lateral femur over 12 months compared with the ≥20% TWL group (−3.83 ± 8.18 msec vs. 2.47 ± 6.54 msec, respectively), whereas no significant differences were observed on the medial femoral compartment (P = 0.385, P = 0.551, and P = 0.511 for bulk, superficial and deep regions, respectively). Changes in WOMAC indices over 12 months were significantly greater in the ≥20% TWL group compared with controls. In the <20% TWL group, pain significantly improved over 12 months compared with controls, while stiffness and function changes were not statistically significant (P = 0.063 and P = 0.051, respectively).Data ConclusionCartilage matrix, measured by T2, showed improvement on lateral femoral cartilage with <20% TWL compared with ≥20% TWL. Bariatric surgery provided significant improvements in knee symptoms with ≥20% TWL compared with conservative WL. This effect is also seen to some extent with <20% TWL compared with conservative WL.Level of Evidence2Technical EfficacyStage 4
