Abstract PurposePolycystic ovary syndrome (PCOS) is a common cause of endocrine disorder and infertility among womenin which is related with low grade inflammation. Therefore, this current randomized, double-blind, placebo-controlledclinical trial assessed the effects of green cardamom supplementation on inflammatory markers and gene expressionamong obese women with PCOS.MethodsWe included 194 obese PCOS women that gave all of them low calorie diet. These subjects were randomlydivided in two studied groups including intervention with 3 g/day green cardamom (n=99) and placebo groups (n=95).Anthropometric indices, androgen hormones, and inflammatory factors (tumor necrosis factor-a (TNF-α), Interleukin6 (IL-6), and C- reactive protein (CRP)) were assessed before and after four months intervention. Their TNF-α, IL-6,and CRP genes expression level were measured using reverse transcription-polymerase chain reaction (RT-PCR)method.ResultsAnthropometric indices were improved in both two studied groups (P<0.001). Among androgen hormonesluteinizing hormone, androstenedione, and dehydroepiandrosterone were significantly decreased (P<0.001), as wellas, follicle-stimulating hormone was significantly increased (P<0.001) in the green cardamom group. Our findingsshowed that TNF-α, IL-6, and CRP serum were significantly decreased after the intervention with green cardamomplus low calorie diet (P<0.001). In addition, the expression level of TNF-α and CRP genes were significantly decreasedin intervention groups (P<0.001).ConclusionsThis present study support the beneficial anti-inflammatory effect of green cardamom on theinflammatory status in the PCOS women.Level of evidenceLevel I, randomized clinical trialTrial registrationThis trial was registered with the Iranian Clinical Trials Registry (registration number:IRCT20200608047697N1). 1 August, 2020; https://www.irct.ir/trial/48748

Abstract Background The present study was designed to determine whether zinc supplementation would increase the effects of restricted calorie diet (RCD) on obesity. Methods and materials A randomized, double-blind clinical trial was performed on 40 obese subjects who were randomly assigned to receive zinc supplements (30 mg/day) or placebo for a period of 15-weeks. Both groups were under a restricted calorie diet (~ 300 kcal lower than the estimated energy requirement). Anthropometric measurements, biochemical markers, appetite, and dietary intakes were determined during the study period. Results The reductions of body weight, body mass index, waist circumference, and hip circumference were significantly higher in the zinc group compared to the placebo group (P = 0.032, 0.025, 0.003, and 0.0001, respectively). Lower levels of high sensitivity C-reactive protein, apelin, homeostatic model assessment of insulin resistance (HOMA-IR), and appetite score were observed in the zinc group in comparison with the placebo group (P = 0.0001, 0.001, 0.031 and 0.001 respectively). Conclusion This study indicates that Zn supplementation with a restricted calorie diet has favorable effects in reducing anthropometric measurements, inflammatory markers, insulin resistance and appetite in individuals with obesity, and may play an effective role in the treatment of obesity. Trial registration This clinical trial was registered at clinicaltrials.gov at the U.S. National Library of Medicine (NCT02516475).

Obesity is commonly associated with a high incidence and prevalence of dyslipidaemia, cardiovascular disease and Type II diabetes. Interestingly, studies have also reported decreased antioxidant levels in obese subjects. This may constitute an independent risk factor in the pathogenesis of coronary artery disease as obese subjects would have a decreased capacity to prevent the oxidative modification of low-density lipoproteins, which is a mechanism suggested as central to the development of atherogenesis. As part of a study to investigate responses to weight loss, we have assessed the effects on GSH status of a decrease in body mass of 5%, either after 6 days of complete starvation or 11 days of a very low calorie diet (2.55MJ/day). There were significant differences between the two groups in the synthesis rate of erythrocyte GSH in response to weight loss. Both the fractional and the erythrocyte synthesis rate of GSH decreased significantly (P<0.01) in the starvation group by 22% and 16% respectively. In contrast, no change in synthesis rates was observed in the very low calorie diet group (P>0.05). Total erythrocyte concentration of GSH was unaffected by the weight loss within both groups. These results suggest that erythrocyte GSH synthesis is depressed in response to a very rapid weight loss induced by fasting. An acute reduction in GSH synthesis in response to a rapid weight loss may constitute a risk factor during periods of increased GSH demands.
