An analysis of data from participants who self-reported higher body weight was conducted (n = 1716). The mean (standard deviation) age was 55.92 (15.94) years and 71.3% and 28.7% identified themselves as women and men, respectively. Gender differences in perceived stress, desire for weight loss, trust in physicians, body affirmation, and perceived weight discrimination were examined. Perceived stress and perceived weight discrimination were significantly higher in women than in men, while trust in physicians and body affirmation was higher in men than women. Trust in physicians and body affirmation were both negatively associated with perceived stress. Perceived weight discrimination and desire for weight loss were both positively associated with perceived stress. Trust in physicians, body affirmation, and perceived weight discrimination were examined as mediators of the observed gender differences between men and women. Trust in physicians, body affirmation, and perceived weight discrimination were significant mediators of the relationship between gender and perceived stress. These results suggest that a possible point of intervention for addressing gender differences in rates of perceived stress among higher body weight adults may be to increase trust in physicians, encourage body affirmation, and reduce weight discrimination.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":"38 S1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139228087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, sulforaphane (SFN) has been the subject of studies due to its anti-cancer, anti-inflammatory, antioxidant and potential anti-obesity effects. Lately, some studies have also reported the anti-obesogenic potential of chlorophyll. In this study, we evaluated the anti-obesity effects of SFN and chlorophyll a (Chlo.a) in C57BL/6J mice fed with a Western diet, rich in sugar and fat. The study lasted 14 weeks, and for the last 4 weeks SFN (0.25 or 0.5 mg/kg/day) or Chlo.a (0.2 or 0.5 mg/kg/day) was administered orally. The results showed that supplementation with SFN or Chlo.a resulted in an increase in body temperature and a reduction in the size of adipocytes. However, the administration of SFN or Chlo.a for 4 weeks did not decrease the body weight gain or hepatic steatosis, and increased hepatic ROS counterbalancing with an increase in SOD activity. In conclusion, in the animal model used, treatment with SFN or Chlo.a did not show strong anti-obesity effects; however, slight improvements were observed with the supplementation of these compounds.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139262826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among children, this trend is alarming due to the premature onset of MetS. The data regarding how the structure and composition of gastrointestinal (GIT) microbiota either promote or attenuate obesity and MetS are limited. Objectives: We carried out this study to investigate the relationship between microbial profiles and diagnosis of MetS among children with obesity. Fifty subjects with a diagnosis of obesity or Mets were enrolled. We collected clinical information, demographic data, dietary records, and stool specimens. Overall, there was no significant difference in the diversity of GIT microbiota between the two subgroups of children with obesity or MetS. We also found no differences in the diversity of GIT microbiota between the sexes and blood pressure categories. However, we observed a significant difference between the structure, composition, and diversity of the gut microbiome when the subjects were stratified using a BMI cut-off of 30. Subjects with a BMI ≥ 30 had a lower abundance of Bacteroidetes and a greater abundance of Actinobacteria and Firmicutes compared to those with a BMI value of less than 30. This gut microbiota signature is more like the GIT microbiome profile of adults with obesity and may represent accelerated changes among children. Additional studies are needed to investigate the role of obesity in the maturation of gut microbiota in children with morbid obesity.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134913566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MicroRNAs (miRNAs) have emerged as key regulators in various biological processes, including metabolism, inflammation, and tissue remodeling, making them pivotal players in obesity-related pathologies. This review aims to provide comprehensive insights into the roles of miRNAs in obesity, with a particular emphasis on their involvement in the pathogenesis of CKD and cardiovascular disorders. We highlight the involvement of specific miRNAs in adipose tissue development, energy homeostasis, inflammation, and insulin resistance, contributing to the pathogenesis of obesity. Moreover, we explore the impact of miRNAs on renal fibrosis and inflammation, giving clues on their roles in the development and progression of CKD. Additionally, we discuss the influence of miRNAs on endothelial dysfunction, atherosclerosis, and cardiac remodeling, emphasizing their contribution to obesity-related cardiovascular disorders. Understanding the regulatory functions of miRNAs in these interconnected conditions holds promise for improved diagnosis, prognosis, and therapeutic interventions. Indeed, miRNAs are potential diagnostic biomarkers for obesity-related diseases, although challenges remain to be elucidated before their clinical translation. Furthermore, we highlight the emerging strategies that target miRNAs as therapeutic interventions to mitigate the detrimental effects of obesity on kidney and cardiovascular health.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135740180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the metabolic profile of Ltx recipients and its association with body fat distribution. Adults who underwent de novo elective cadaveric-donor Ltx were eligible. Metabolic syndrome (MS) was diagnosed based on the adapted International Diabetes Federation, the American Heart Association, and the National Heart, Lung, and Blood Institute guidelines. We recruited 100 patients with a mean age of 54 years, of whom 70% were men. Overall, 54% met the criteria for MS, most of which comprised new-onset cases. Excessive fat accumulation in liver donors was found to be associated with an increased metabolic risk in liver recipients. Haemoglobin A1C (OR: 8.962, 95% CI: 2.188–84.545, p = 0.013), ferritin (OR: 1.024, 95% CI: 1.005–1.054, p = 0.038), and de novo hypertriglycaeridemia (OR 27.957, 95% CI: 2.626–752.121, p = 0.014) were found to be independently associated with de novo MS. After a step-wise multivariate analysis, only the anthropometric obesity indices were significantly associated with abdominal fat distribution in Ltx recipients. Metabolic complications were common in liver recipients. Both pre- and post-Ltx factors impacted MS development in liver recipients and determined abdominal fat distribution.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43024678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time-restricted feeding (TRF), in which food accessibility is restricted to a variable period of 8–10 h, especially in the active phase, inducing a prolonged fasting period, is a strategy with potential effects in preventing obesity. Evidence in preclinical studies demonstrated that TRF attenuates the impacts of metabolic disturbances related to high-fat diet feeding in rodents. Through these discoveries, there has been growing interest in revealing the effects associated with TRF in preventing obesity and its comorbidities, as well as investigating its effects in humans. Although TRF is a promising alternative to reduce the impact of obesity, it is necessary to investigate the results on skeletal muscle tissue. Muscle tissue is important for body energy expenditure; however, caloric restriction can negatively impact protein turnover and induce loss of muscle mass, influencing the basal metabolic rate and weight loss. This mini review examined the scientific literature exploring the effects of time-restricted feeding (TRF) on muscle mass. Although still incipient, the findings related to TRF applied to obese individuals highlight the importance of carrying out dietary control, as well as the consumption and fractionation of proteins, to maintain a balanced protein turnover and, consequently, muscle mass.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41644516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, cases of AN associated with food addiction (FA) were described in almost all patients (69%), bringing a controversial aspect to the restrictive subtype (AN-r) that, in theory, even in the absence of binge eating, would present difficulties regarding control. Objectives: To report a case of an adolescent with AN-r associated with FA. Methods: Clinical history, current status, psychiatric diagnosis, and scores on scales to assess FA, food craving, and binge eating were analyzed. Results: This case report emphasizes the importance of new diagnostic tools to identify FA and whether it exists in people with AN-r beyond distress regarding eating behavior, cravings, and guilt. Eating behavior also presents a negative value that delays the elaboration process and the emergence of food cravings. In addition, an analysis of the association between the diagnostic criteria for substance use disorder, binge eating disorder, anorexia nervosa, and bulimia nervosa with the Yale Food Addiction Scale statements and criteria was discovered. Conclusions: Based on the characteristics of AN, emotional dysregulation and eating difficulties seem to overlap with FA symptoms.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45731486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We searched the following electronic databases: PubMed (Medline), Science Direct, Scopus, and Web of Science. We included ten experimental articles that used green tea to treat induced obesity in rodents. Green tea reduced the weight of white and brown adipose tissue, positively regulated gene expression and microRNA that regulate the metabolism of adipose tissue, and morphological changes were identified as beige tissue. According to the results found, the factors involved in this induction to browning are PPARγ, PGC-1α, UCP1, CPT, and PRDM16. Therefore, green tea promotes the browning of adipose tissue in rodents.

Six healthy women, aged 33–55 years with a BMI of 27–33 kg/m2, were randomized to first adhere to either a low- or high-protein IER diet using whole foods for three weeks. They then returned to their regular diets for a week, after which they adhered to the second diet for three weeks. Each test diet consisted of three low-energy intake days followed by four isocaloric energy intake days. The diets differed only in protein content. High-sensitivity C-reactive protein (hs-CRP), glucose, satiety, body weight, and waist circumference were measured at the beginning and end of each dietary intervention. Most participants showed reductions in hs-CRP levels from baseline on both IER diets but reported greater satiety when adhering to the higher protein IER diet. Overall, the IER diets reduced body weight and appeared to decrease inflammation in these overweight women, and the higher protein version enhanced satiety, which may lead to greater long-term dietary adherence.","PeriodicalId":93598,"journal":{"name":"Obesities","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48270076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
