OBJECTIVES: There is no consensus on whether cognitive control over food intake (i.e. restrained eating) is helpful, merely ineffective or actually harmful in weight management. We examined the interplay between genetic risk of obesity, restrained eating and changes in body weight and size. METHODS: Participants were Finnish 25- to 74-year-olds who attended the DILGOM study at baseline in 2007 and follow-up in 2014. At baseline (n=5024), height, weight and waist circumference (WC) were measured in a health examination and participants self-reported their weight at age 20 years...

BACKGROUND/OBJECTIVE: The term macrosomia is used to describe neonates with a birth weight of 4000 g or more. Macrosomia is a potential risk factor for obesity and metabolic syndromes in postnatal and adult life, yet little is known about its associations with metabolic difference in the early-age. We performed metabolic profiling of umbilical cord blood to discover differential metabolites of macrosomia. METHODS: We conducted a case-control study of full-term singletons with normal maternal glucose tolerance [50 cases (macrosomia, birth weight ⩾4000 g); 50 controls (normal weight, birth weight 2500-3999 g)]...

BACKGROUND/OBJECTIVES: We aimed to evaluate mitochondrial biogenesis (MB), structure, metabolism, and dysfunction in abdominal adipose tissue from male pediatric patients with obesity. SUBJECTS/METHODS: Samples were collected from five children with obesity (percentile ⩾95) and five eutrophic boys (percentile ⩾5/⩽85) (8-12 years old) following parental informed consent. We analyzed the expression of key genes involved in MB (SIRT1, PPARγ, PGC1α, NRF1, NRF2, and TFAM) and surrogates for mitochondrial function/structure/metabolism (porin, TOMM20, complex I and V, UCP1, UCP2, SIRT3, SOD2) by Western blot...

BACKGROUND/OBJECTIVE: Previous research has focused on associations between dietary fat and body mass index (BMI), but the contributions of different types of fat to BMI remain unclear. The purpose of this study is to estimate whether plasma phospholipid omega-3 (n-3), omega-6 (n-6), or trans fatty acids are associated with BMI at baseline and with subsequent BMI changes over time; and whether total phospholipid n-6 or trans fatty acids modify any association between phospholipid n-3 and BMI...

BACKGROUND/OBJECTIVE: Fat distribution is a strong and independent predictor of type 2 diabetes (T2D) and cardiovascular disease (CVD) and is usually determined using conventional anthropometry in epidemiological studies. Dual-energy X-ray absorptiometry (DXA) can measure total and regional adiposity more accurately. Nonetheless, whether DXA provides more precise estimates of cardiovascular risk in relation to total and regional adiposity is not known. We determined the strength of the associations between DXA- and conventional anthropometry determined fat distribution and T2D and CVD risk...

BACKGROUND/OBJECTIVES: Expanding visceral adiposity is associated with increased inflammation and increased risk for developing obesity-related comorbidities. The goal of this study was to examine high fat diet (HFD)-induced differences in adipocyte size and cytokine/chemokine expression in visceral and subcutaneous adipose depots in obesity-prone (OP) and obesity-resistant (OR) rats. METHODS: OP and OR rats were fed either a low fat diet (LFD, 10% kilocalories from fat) or HFD (60% kilocalories from fat) for 7 weeks...

BACKGROUND: Solid epidemiological evidences connect obesity with incidence, stage, and survival in pancreatic cancer. However, the underlying mechanistic basis linking adipocytes to pancreatic cancer progression remain largely elusive. We hypothesized that factors secreted by adipocytes could be responsible for epithelial-to-mesenchymal transition (EMT) induction and, in turn, a more aggressive phenotype in models of pancreatic preneoplastic lesions. METHODS: We studied the role of factors secreted by two adipogenic model systems from primary human Bone Marrow Stromal Cells (hBMSC) in an in vitro experimental cell transformation model system of human pancreatic ductal epithelial (HPDE) cell stably expressing activated KRAS (HPDE/KRAS),RESULTS:We measured a significant induction of EMT and aggressiveness in HPDE and HPDE/KRAS cell lines when cultured with medium conditioned by fully differentiated adipocytes (ADIPO(CM)) if compared with the same cells cultured with medium conditioned by hBMSC (hBMSC(CM)) from two different healthy donors...

BACKGROUND: With the growing evidence that other tissues, apart from adipose, could have strong relevance to obesity, it is necessary to comprehensively understand the relationship between obesity and other tissues, and to point out the most relevant tissues. METHODS: There were 549 participants with 20 different tissue types involved in this study. We firstly employed both Spearman's correlation test and weighted correlation network analysis (WGCNA) to identify BMI-related genes...

BACKGROUND/OBJECT: Inter-individual variability in weight loss during obesity treatment is complex and poorly understood. Here we use whole body and tissue approaches to investigate fuel oxidation characteristics in skeletal muscle fibers, cells, and distinct circulating protein biomarkers before and after a high fat meal (HFM) challenge in those who lost the most (obese diet-sensitive; ODS), vs the least (obese diet-resistant; ODR) amount of weight in a highly controlled weight management program...

OBJECTIVE: Obesity is now the most prevalent chronic disease in the United States, which amounts to an estimated $147 billion in health care spending annually. The Affordable Care Act (ACA) enacted in 2010, included provisions for private and public health insurance plans that expanded coverage for lifestyle/behavior modification and bariatric surgery for the treatment of obesity. Pharmacotherapy, however, has not been included despite their evidence-based efficacy. We set out to investigate the coverage of FDA-approved medications for obesity within Medicare, Medicaid, and ACA-established marketplace health insurance plans...

BACKGROUND: Global prevalence of overweight/obesity and gestational diabetes (GDM) is increasing. In pregnant women both conditions affect offspring's later health. Overweight/obesity is a risk factor of GDM; to what extent maternal overweight/obesity explains long-term effects of GDM in offspring is unknown. OBJECTIVE: To evaluate effects of maternal pre-pregnancy overweight/obesity (BMI ⩾25 kg/m(2)) and GDM, occurring together or separately, on body composition among adult offspring...

BACKGROUND: Obesity is related to a tendency to discount the future. Information regarding inter-meal interval (IMI) allows meal planning. We sought to assess how obese, overweight, and lean people select portion sizes based on the length of an IMI. We hypothesised that individuals with a high BMI would discount information about the IMI. In addition, we investigated how reduced sensitivity to IMIs relates to monetary temporal discounting. METHODS: Participants (lean, n=35; overweight, n=31; obese, n=22), selected lunchtime portion sizes in response to information about the timings of their next meal...

BACKGROUND: The gut microbiota associates with obesity and related disorders, but recent meta-analyses have found that this association is, at best, of small effect. We argue that such analyses are flawed by the use of BMI as sole proxy for disease, and explore a classification method that distinguishes the cardiometabolic health status of individuals to look for more comprehensive associations between gut microbes and health. METHODS: We analyzed a 441 community-dwelling cohort on which we obtained demographic and health information, anthropometry and blood biochemistry data that served to categorize participants according to BMI, cardiometabolic health status and body size phenotypes...

BACKGROUND AND AIM: The well-established link between body fat distribution and metabolic health has been suggested to act through an impact on the remodeling capacity of the adipose tissue. Remodeling of the adipose tissue has been shown to affect body fat distribution and might affect the ability to lose weight. We aimed to study the effect of weighted genetic risk scores (GRSs) on weight loss based on single-nucleotide polymorphisms (SNPs) associated with waist-hip-ratio adjusted for body mass index (WHRadjBMI)...

BACKGROUND/OBJECTIVES: Obesity (body mass index (BMI) ⩾30) is associated with an increased risk of estrogen-dependent breast cancer after menopause. Levels of aromatase, the rate-limiting enzyme in estrogen biosynthesis, are elevated in breast tissue of obese women. Recently, the regulation of aromatase by the p53-HIF1α/PKM2 axis was characterized in adipose stromal cells (ASCs) of women with Li-Fraumeni Syndrome, a hereditary cancer syndrome that predisposes to estrogen-dependent breast cancer...

BACKGROUND: The National Child Measurement Programme (NCMP) records weight and height and assesses overweight-obesity patterns in English children using body mass index (BMI), which tends to underestimate body fatness in South Asian children and overestimate body fatness in Black children of presumed African ethnicity. Using BMI adjustments to ensure that adjusted BMI was similarly related to body fatness in South Asian, Black and White children, we reassessed population overweight and obesity patterns in these ethnic groups in NCMP...

BACKGROUND: Obesity induces significant changes in lipid mediators, however, the extent to which these changes persist after weight loss has not been investigated. SUBJECTS/METHODS: We fed C57BL6 mice a high fat diet to generate obesity and then switched the diet to a lower fat diet to induce weight loss. We performed a comprehensive metabolic profiling of lipid mediators including oxylipins, endocannabinoids, sphingosines and ceramides in key metabolic tissues including adipose, liver, muscle, hypothalamus and plasma...

Low birth weight followed by rapid postnatal weight gain is associated with increased risks for obesity and diabetes in adulthood. Modulation of glucagon-like-peptide 1 (GLP-1) secretion by (epi)genetic mechanisms or nutrition may influence in part this risk. Formula fed infants born small-for-gestational-age (SGA) have higher circulating GLP-1 at age 4 months than breastfed SGA or appropriate-for-gestational-age (AGA) infants. Here, we assessed GLP-1 concentrations in healthy AGA (n=149) and SGA (n=107) subjects at age 12 months, and their association with endocrine-metabolic and body composition parameters and GLP-1 receptor (GLP-1R) rs6923761 and rs3765467 polymorphisms...
