Maternal obesity induces hippocampal functional changes and leads to deficits in cognitive functions, such as learning and memory in offspring. We investigated the protective effects of physical exercise against cognitive function deficit in offspring born to obese mothers. Neurotrophic factors, neurogenesis, and apoptosis were analyzed in the hippocampus and dentate gyrus of offspring. Four-week-old female rats were fed a high-fat diet (HFD) for 20 weeks: 12 weeks prior to mating, and 8 weeks during pregnancy and breast-feeding...

Idiopathic intracranial hypertension (IIH) is associated with obesity, and weight loss is important to reduce intracranial pressure and improve visual function. A 38-year-old woman with IIH followed an extreme diet, which resulted in 30% weight loss (BMI moved from 34.9 to 24.6). Weight loss resulted in a significant reduction of papilloedema, normalization of intracranial pressure and improvement in headache pattern, but also induced a state of initial malnutrition, relevant depression and disability. She was discharged with the indication to start a controlled diet and improve physical activity: clinical situation get back to stability, with the patient loosing further weight (BMI=21...

Intermittent fasting (IF) and high intensity interval training (HIIT) are effective lifestyle interventions for improving body composition and overall health. However, the long-term effects of IF and potential synergistic effects of combining IF with exercise are unclear. The purpose of the study was to investigate the long-term effects of IF, with or without HIIT, on body composition and markers of metabolic health in diet-induced obese mice. In a randosmised, controlled design, 8-week-old C57BL/6 mice (males ( n = 39) and females ( n = 49)) were fed a high fat (HF) and sugar (S) water diet (30% ( w / v )) for 24-weeks but were separated into five groups at 12-weeks: (1) 'obese' baseline control (OBC); (2) no intervention (CON); (3) intermittent fasting (IF); (4) high intensity intermittent exercise (HIIT) and (5) combination of dietary and exercise intervention (IF + HIIT)...

Exercise and resveratrol supplementation exhibit anti-obesity functions in the long term but have not been fully investigated yet in terms of their early potential effectiveness. Mice fed with high-fat diet were categorized into control (Cont), exercise (Ex), resveratrol supplementation (Res), and exercise combined with resveratrol supplementation (Ex + Res) groups. In the four-week period of weight loss, exercise combined with resveratrol supplementation exerted no additional effects on body weight loss but significantly improved whole-body glucose and lipid homeostasis...

The prevalence of obesity, measured by body mass index, has risen to unacceptable levels in both men and women in the United States and worldwide with resultant hazardous health implications. Genetic, environmental, and behavioral factors influence the development of obesity, and both the general public and health professionals stigmatize those who suffer from the disease. Obesity is associated with and contributes to a shortened life span, type 2 diabetes mellitus, cardiovascular disease, some cancers, kidney disease, obstructive sleep apnea, gout, osteoarthritis, and hepatobiliary disease, among others...

The majority of fat in the human body is stored as triacylglycerols in white adipose tissue. In the obese state, adipose tissue mass expands and excess lipids are stored in non-adipose tissues, such as skeletal muscle. Lipids are stored in skeletal muscle in the form of small lipid droplets. Although originally viewed as dull organelles that simply store lipids as a consequence of lipid overflow from adipose tissue, lipid droplets are now recognized as key components in the cell that exert a variety of relevant functions in multiple tissues (including muscle)...

Previously, we monitored the expression level of the pro-apoptotic proteins caspase-3 and cleaved poly-ADP-ribose polymerase in the skeletal muscle of high-fat diet-induced obese rats in order to assess muscle damage. In this study, we analyzed whether exercise or dietary adjustment was more effective at preventing high-fat diet-induced muscle damage. High-fat diet-induced obese rats were divided into three groups: the high-fat diet (HFD), the combined high-fat diet and exercise (HFD+EXE), and the dietary adjustment (DA) groups...

BACKGROUND: Hispanic children are disproportionally overweight and obese compared to their non-Hispanic white counterparts in the US. Community-wide, multi-level interventions have been successful to promote healthier nutrition, increased physical activity (PA), and weight loss. Using community-based participatory approach (CBPR) that engages community members in rural Hispanic communities is a promising way to promote behavior change, and ultimately weight loss among Hispanic children...

BACKGROUND: The global prevalence of childhood and adolescent obesity is high. Lifestyle changes towards a healthy diet, increased physical activity and reduced sedentary activities are recommended to prevent and treat obesity. Evidence suggests that changing these health behaviours can benefit cognitive function and school achievement in children and adolescents in general. There are various theoretical mechanisms that suggest that children and adolescents with excessive body fat may benefit particularly from these interventions...

Eating behaviors (cognitive restraint, flexible and rigid restraint, disinhibition, hunger) have been associated with obesity and weight loss success in middle-aged individuals, but little is known about these relationships in older adults. This study examined relationships between eating behaviors and weight loss in overweight/obese older women (n = 61; 69 ± 3.6 years; body mass index = 31.1 ± 5.0 kg/m2 ) completed a 6-month behavioral weight loss intervention. Baseline, postintervention, and change measures of eating behaviors (51-items Three-Factor Eating Questionnaire) were assessed for relationships with weight loss...

Obesity is recognized as a national and global health epidemic. Commercial truck drivers (CTDs) have a higher obesity rate and lower life expectancy compared with the general population. CTDs work sedentary jobs with long hours that pose barriers to healthy eating and regular exercise. An evidenced-based practice (EBP) change project that used motivational interviewing (MI) and education regarding diet and exercise over a 4-week period was found to have a positive impact on CTDs behavior. Results revealed an increase in aggregated self-efficacy for weight loss (14...

High-Fat-Diet (HFD)-induced obesity is a major contributor to heart and mobility premature aging and mortality in both Drosophila and humans. The dSir 2 genes are closely related to aging, but there are few directed reports showing that whether HFD could inhibit the expression dSir 2 genes. Endurance exercise can prevent fat accumulation and reverse HFD-induced cardiac dysfunction. Endurance also delays age-relate functional decline. It is unclear whether lifetime endurance exercise can combat lifetime HFD-induced heart and mobility premature aging, and relieve the harmful HFD-induced influence on the dSir 2 gene and lifespan yet...

BACKGROUND & AIMS: Reshape Duo is a saline-filled dual, integrated intra-gastric balloon (IGB) approved by the Food and Drug Administration for weight loss in patients with obesity. In a prospective, randomized trial, obese patients who received the balloon had significantly greater percent excess weight loss (%EWL) compared patients treated with diet and exercise alone. However, there are limited data on the real-world efficacy of the Reshape balloon. METHODS: We performed a retrospective study of data collected from 2 academic centers and 5 private practices in which all patients paid for the IGB and follow-up visits out of pocket...

The dysregulation of adipokine secretion owing to adiposopathy can contribute to the pathogenesis of obesity-related disorders. Being that exercise is an advised strategy against obesity-induced adiposopathy, we aimed to analyze the role of physical exercise as a preventive and therapeutic strategy against high-fat diet (HFD)-induced adipokine and ghrelin alterations. Rats were pair-fed the Lieber De Carli standard diet (S, 35 Kcal% fat) or HFD (71 Kcal% fat) over 17 weeks. Animals were assigned into four groups as follows: standard diet sedentary (SS), standard diet voluntary physical activity (SVPA), high-fat diet sedentary (HS), and high-fat diet voluntary physical activity (HVPA)...

PURPOSE: Obesity results in decreased lung function and increased inflammation. Moderate aerobic exercise (AE) reduced lung inflammation and remodeling in a variety of respiratory disease models. Therefore, this study investigated whether AE can attenuate a diet-induced obesity respiratory phenotype; including airway hyper-responsiveness (AHR), remodeling and inflammation. METHODS: Sixty C57Bl/6 male mice were distributed into four groups: control lean (CL), exercise lean (EL), obese (O) and obese exercise (OE) groups (2 sets of 7 and 8 mice per group; n = 15)...

Obesity prevalence is higher in rural compared to urban residents. Rural health clinics offer a potential venue for delivery of weight management. However, traditional programs require travel to attend on-site meetings which is impractical or inconvenient for rural residents. Clinic staff in most rural settings are unlikely to be trained to provide effective weight management. Remote delivery using group phone conferences (GP) or individual phone calls (IP), by staff associated with rural clinics eliminates the need for travel to attend on-site meetings...
