The WHO infant feeding guidelines, including those for complementary feeding (CF), are very prescriptive, largely based on the outcomes of exclusive breastfeeding, and have a bias towards undernutrition. Consideration of longer-term outcomes related to overnutrition, the predominant nutrition problem in affluent countries, is limited. Compared to the ongoing and often zealous debates regarding the short- and long-term benefits of exclusive breastfeeding to 6 months in affluent countries, exposures (particularly feeding practices) and outcomes related to CF, independent of exclusive breastfeeding, have received little attention...

BACKGROUND: Understanding risk factors that may vary culturally can help improve preventive strategies for obesity. This is the first cross-sectional study aimed to determine the risk factors for overweight/obesity in children aged 2-6 years in a central Anatolian city in Turkey. METHODS: A total of 1582 children (1351 healthy, 231 overweight/obese) aged 2-6 years were included from the Anthropometry of Turkish Children aged 0-6 years database. Age, gender, birth weight, birth order, mother's age, mother's body mass index (BMI), weight gain of mothers during pregnancy, presence of gestational diabetes, breastfeeding duration, history of formula feeding, mother's and father's education, mother's job, monthly income, smoking at home and physical activity, sleep duration and duration of television (TV) watching of the children were evaluated as independent risk factors...

BACKGROUND: A majority of adipose tissue present in the newborn possess the unique mitochondrial protein, uncoupling protein (UCP1). It is thus highly metabolically active and capable of producing 300 times more heat per unit mass than any other organ in the body. The extent to which maternal obesity and/or an obesogenic diet impacts on placental function thereby resetting the relative distribution of different types of fat in the fetus is unknown. SUMMARY: Developmentally the majority (if not all) fat in the fetus can be considered as classical brown fat, in which UCP1 is highly abundant...

Dietary gluten causes severe disorders like celiac disease in gluten-intolerant humans. However, currently understanding of its impact in tolerant individuals is limited. Our objective was to test whether gliadin, one of the detrimental parts of gluten, would impact the metabolic effects of an obesogenic diet. Mice were fed either a defined high-fat diet (HFD) containing 4% gliadin (n = 20), or a gliadin-free, isocaloric HFD (n = 20) for 23 weeks. Combined analysis of several parameters including insulin resistance, histology of liver and adipose tissue, intestinal microbiota in three gut compartments, gut barrier function, gene expression, urinary metabolites and immune profiles in intestinal, lymphoid, liver and adipose tissues was performed...

Obesity has become pandemic owing to an obesogenic environment (inexpensive calorie dense food, technologies and structure of communities that reduce or replace physical activity, and inexpensive nonphysical entertainment) and excessive emphasis on low fat intake resulting in excessive intake of simple carbohydrates and sugar. Effects are greater for women owing to their smaller size and extra weight gain with each pregnancy, with 38% of American adult women being obese. Women are responsible for more than three-fourths of the more than 400 billion dollars of excess direct health care expenditures due to obesity...

INTRODUCTION: The prevalence of obesity is greater among adults living in rural compared to urban areas of the USA. Greater obesity risk among rural adults persists after adjusting for obesity-related behaviors and sociodemographic factors. With the rural-urban obesity disparity greatest among younger adults, it is important to examine the complexity of factors that may increase the risk for excess body weight in this population so that effective preventive interventions can be implemented...

Faced with the current obesity epidemic, this article problematizes the way the right to food is often circumscribed to situations of nutritional deficit. It is argued that the right to adequate food is violated in obesogenic environments and that protection of the right requires the establishment of measures to regulate advertising and marketing practices regarding ultra-processed products. The work suggests that the main barriers to the implementation of such measures are the strategies employed by Big Food; among these, strategies that have the scientific community as a target and/or means are highlighted...

Neural plasticity is an intrinsic and essential characteristic of the nervous system that allows animals "self-tuning" to adapt to their environment over their lifetime. Activity-dependent synaptic plasticity in the central nervous system is a form of neural plasticity that underlies learning and memory formation, as well as long-lasting, environmentally-induced maladaptive behaviors, such as drug addiction and overeating of palatable hyper-caloric (PHc) food. In western societies, the abundance of PHc foods has caused a dramatic increase in the incidence of overweight/obesity and related disorders...

Optimal defaults is a compelling model from behavioral economics and the psychology of human decision-making, designed to shape or "nudge" choices in a positive direction without fundamentally restricting options. The current study aimed to test the effectiveness of optimal (less obesogenic) defaults and parent empowerment priming on health-based decisions with parent-child (ages 3-8) dyads in a community-based setting. Two proof-of-concept experiments (one on breakfast food selections and one on activity choice) were conducted comparing the main and interactive effects of optimal versus suboptimal defaults, and parent empowerment priming versus neutral priming, on parents' health-related choices for their children...

REVIEW
Clare H Llewellyn, Alison Fildes
PURPOSE OF REVIEW: There is considerable variability in human body weight, despite the ubiquity of the 'obesogenic' environment. Human body weight has a strong genetic basis and it has been hypothesised that genetic susceptibility to the environment explains variation in human body weight, with differences in appetite being implicated as the mediating mechanism; so-called 'behavioural susceptibility theory' (BST), first described by Professor Jane Wardle. This review summarises the evidence for the role of appetite as a mediator of genetic risk of obesity...

Peri-conceptional exposure to maternal obesogenic nutrition is associated with in utero programming of later-life overweight and metabolic disease in the offspring. We aimed to investigate whether dietary intervention with a modified fatty acid quality in an obesogenic high-calorie (HC) diet during the preconception and gestational phases can improve unfavourable effects of an adipogenic maternal environment. In NMRI mice, peri-conceptional and gestational obesity was induced by feeding a HC diet (controls), and they were compared with dams on a fat-modified (Fat-mod) HC diet of the same energy content but enriched with medium-chain fatty acids (MCFAs) and adjusted to a decreased ratio of n-6 to n-3 long-chain polyunsaturated fatty acids (LC-PUFAs)...

Individuals can lose body weight and improve health status on a wide range of energy (calorie) restricted dietary interventions. In this paper, we have reviewed the effectiveness of the most commonly utilized diets, including low-fat, low-carbohydrate and Mediterranean approaches in addition to commercial slimming programmes, meal replacements and newly-popularized intermittent fasting diets. We also consider the role of artificial sweeteners in weight management. Low-fat diets tend to improve LDL-cholesterol most, whilst lower-carbohydrate diets may preferentially improve triglycerides and HDL-cholesterol, however differences between diets are marginal...

BACKGROUND/OBJECTIVES: Targeting obesogenic features of children's environment that are amenable to change represents a promising strategy for health promotion. The school food environment, defined as the services and policies regarding nutrition and the availability of food in the school and surrounding neighborhood, is particularly important given that students travel through the school neighborhood almost daily and that they consume a substantial proportion of their calories at school...

REVIEW
P Jia, X Cheng, H Xue, Y Wang
Geographic information systems (GIS) data/methods offer good promise for public health programs including obesity-related research. This study systematically examined their applications and identified gaps and limitations in current obesity-related research. A systematic search of PubMed for studies published before 20 May 2016, utilizing synonyms for GIS in combination with synonyms for obesity as search terms, identified 121 studies that met our inclusion criteria. We found primary applications of GIS data/methods in obesity-related research included (i) visualization of spatial distribution of obesity and obesity-related phenomena, and basic obesogenic environmental features, and (ii) construction of advanced obesogenic environmental indicators...

Effective obesity prevention requires a synergistic mix of population-level interventions including a strong role for government and the regulation of the marketing, labelling, content and pricing of energy-dense foods and beverages. In this paper we adopt the agenda of the Australian Federal Government (AFG) as a case study to understand the factors generating or hindering political priority for such 'regulatory interventions' between 1990 and 2011. Using a theoretically-guided process tracing method we undertook documentary analysis and conducted 27 interviews with a diversity of actors involved in obesity politics...

BACKGROUND: While obesity is well-understood to increase breast cancer risk, the role of the neighborhood obesogenic environment, encompassing social and built environment attributes that influence body size, is poorly understood. METHODS: Using principal components factor analysis, five composite factors (neighborhood socioeconomic status (nSES), urban, mixed-land development, unhealthy food environment, parks), based on geospatial data were developed to characterize the obesogenic environment for 48,247 postmenopausal women in the Multiethnic Cohort, residing predominately in Los Angeles County...

Pediatric obesity develops when a complex biological predisposition collides with an obesogenic environment. To further elucidate the role of genetics in obesity onset, we performed a candidate-gene association study in a young and sportive Italian population by testing the association of functional polymorphisms in ACE (rs4646994), FTO (rs9939609), MC4R (rs17782313) and PPARG (rs1801282) genes with body mass index (BMI) and waist-to-height ratio (WHtR). We also tested the combinations of identified risk genotypes and epistatic interactions among them to determine the existence of cumulative effects in predicting the predisposition to gain weight...

Early-life stress (ES) increases the vulnerability to develop psychopathologies and cognitive decline in adulthood. Interestingly, this is often comorbid with metabolic disorders, such as obesity. However, it is unclear whether ES leads to lasting metabolic changes and to what extent this is associated with the ES-induced cognitive impairments. Here, we used an established chronic ES mouse model (from postnatal day (P) 2 to P9) to investigate the short- and long-term effects of ES exposure on parameters of the adipose tissue and the leptin system (i...
