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: Type 2 diabetes is a prevalent, chronic disease for which diet is an integral aspect of treatment. In our previous trial, we found that recommendations to follow a very low-carbohydrate ketogenic diet and to change lifestyle factors (physical activity, sleep, positive affect, mindfulness) helped overweight people with type 2 diabetes or prediabetes improve glycemic control and lose weight. This was an in-person intervention, which could be a barrier for people without the time, flexibility, transportation, social support, and/or financial resources to attend...

Basement membranes provide structural support to epithelium, endothelium, muscles, fat cells, Schwann cells and axons. Basement membranes are multifunctional: they modulate cellular behavior, regulate organogenesis, promote tissue repair, form a barrier to filtration and tumor metastasis, bind growth factors and mediate angiogenesis. All basement membranes contain type IV collagen (Col IV), laminin, nidogen, and perlecan. Col IV and laminin self-assemble into two independent supramolecular networks that are linked to nidogen and perlecan to form a morphological discernable basement membrane/basal lamina...

BACKGROUND: Obesity research has typically focused on weight change patterns using the whole sample in randomized clinical trials (RCTs), ignoring subsets of individuals with varying weight change trajectories (e.g., continuing to lose, or maintaining weight). The purpose was to explore possible trajectories of weight change and their associated predictors. METHODS: We conducted a secondary analysis of data from two RCTs using standard behavioral treatment for weight loss...

BACKGROUND: Eighty percent of patients who receive bariatric surgery are women, yet the majority of preclinical studies are in male rodents. Because sex differences drive hepatic gene expression and overall lipid metabolism, we sought to determine whether sex differences were also apparent in these endpoints in response to bariatric surgery. METHODS: Two cohorts of age-matched virgin male and female Long-Evans rats were placed on a high fat diet for 3 weeks and then received either Sham or vertical sleeve gastrectomy (VSG), a surgery which resects 80% of the stomach with no intestinal rearrangement...

OBJECTIVE: Monetary contingency contracts (MCCs), in which deposited money is returned contingent on weight loss, could promote weight/adiposity reduction. This study piloted individual- and pair-based MCCs (when refunds are contingent on two individuals losing weight) and assessed effects on weight/body composition. METHODS: Seventy-seven participants with BMI greater than 25 kg/m(2) were recruited. In a non-blinded, randomized controlled trial conducted in a university laboratory setting, participants were randomized in pairs via a computer-generated sequence to one of four conditions: partner with pair-based refund (P-PBR), partner with individual refund (P-IR), individual weight loss with individual refund (I-IR), or no MCC (comparison)...

OBJECTIVES: Arachidonic acid metabolites (eicosanoids) reflect oxidative stress and vascular health and have been associated with anthropometric measures and sex differences in cross-sectional analyses of HIV-infected (HIV+) persons. Telmisartan is an angiotensin receptor blocker and PPAR-γ agonist with potential anti-inflammatory and metabolic benefits. We assessed telmisartan's effects on urine eicosanoids among HIV+ adults with central adiposity on suppressive antiretroviral therapy enrolled in a prospective clinical trial...

Vitamin A is a fat-soluble vitamin important for vision, reproduction, embryonic development, cell differentiation, epithelial barrier function and adequate immune responses. Efficient absorption of dietary vitamin A depends on the fat-solubilizing properties of bile acids. Bile acids are synthesized in the liver and maintained in an enterohepatic circulation. The liver is also the main storage site for vitamin A in the mammalian body, where an intimate collaboration between hepatocytes and hepatic stellate cells leads to the accumulation of retinyl esters in large cytoplasmic lipid droplet hepatic stellate cells...

Jonathan C K Wells
In their seminal book "Worldwide variation in human growth," published in 1976, Eveleth and Tanner highlighted substantial variability within and between populations in the magnitude and schedule of human growth. In the four decades since then, research has clarified why growth variability is so closely associated with human health. First, growth patterns are strongly associated with body composition, both in the short- and long-term. Poor growth in early life constrains the acquisition of lean tissue, while compensatory "catch-up" growth may elevate body fatness...

In HIV-infected patients, combined antiretroviral therapy (cART) is associated to adipose tissue redistribution known as lipodystrophy and associated cardiometabolic risk. This study aimed to evaluate the evolution of body composition in HIV-infected patients, with and without lipodystrophy, over 2 yr. We evaluated anthropometric parameters and body composition by whole-body dual-energy X-ray absorptiometry in 144 HIV-infected patients on cART. We defined lipodystrophy by fat mass ratio. Lipodystrophy was present in 45...

In the pancreatic islet, serotonin is an autocrine signal increasing beta cell mass during metabolic challenges such as those associated with pregnancy or high-fat diet. It is still unclear whether serotonin is relevant for regular islet physiology and hormone secretion. Here, we show that human beta cells produce and secrete serotonin when stimulated with increases in glucose concentration. Serotonin secretion from beta cells decreases cyclic AMP (cAMP) levels in neighboring alpha cells via 5-HT1F receptors and inhibits glucagon secretion...

BACKGROUND: Soft-tissue fillers have become important products for facial rejuvenation. Deep fat compartments and facial bones lose volume during the natural aging process. For the most natural-looking results, deep volumetric injections at strategic sites are therefore preferred. Supraperiosteal placement is performed with a sharp needle or a non-traumatic cannula. OBJECTIVES: The primary objective was to determine whether there is a difference in precision between supraperiosteal placement with a sharp needle compared with a non-traumatic cannula in cadaver specimens...

Bariatric surgeries, including Roux-en-Y gastric bypass (RYGB) are currently the best treatment for obesity and obesity-related comorbidities, such as type 2 diabetes. However, the underlying mechanism of bariatric surgeries is not entirely understood. Further investigations are needed to improve the success rate and achieve sustained health benefits. Given that B cell dysregulation is a critical component of etiology in inflammatory diseases, whereas obesity and type 2 diabetes represent two major inflammatory disorders, we investigated the effect of RYGB on B cell inflammation...

BACKGROUND: Obesity is one of the greatest public health challenges worldwide. It is not only a medical but also a philosophical, ecological, economic, sociocultural, and psychological problem as well as a severe consequence of our modern value definition to 'receive more and more'. Therefore, physicians are not able to treat obesity broadly and should not be used as tools to achieve certain weight goals. METHODS: This article presents an outline of conservative obesity therapy...

A D Higginson, J M McNamara
BACKGROUND AND OBJECTIVES: Peoples' attempts to lose weight by low calorie diets often result in weight gain because of over-compensatory overeating during lapses. Animals usually respond to a change in food availability by adjusting their foraging effort and altering how much energy reserves they store. But in many situations the long-term availability of food is uncertain, so animals may attempt to estimate it to decide the appropriate level of fat storage. METHODOLOGY: We report the results of a conceptual model of feeding in which the animal knows whether food is currently abundant or limited, but does not know the proportion of time, there will be an abundance in the long-term and has to learn it...

The terminologies of "body size", "body mass index (BMI)", "body weight", "large BMI" and "obesity" are controversial for defining the effects of "adiposity" or "fat excess" on the outcomes of dialysis and transplant patients. However, probably these terminologies will be continued to be used in the future as well, because of being older and simpler terminologies. In the general population obesity is a powerful risk factor for cardiovascular morbidity and mortality, while, it conferred a survival advantage to dialysis patients...

BACKGROUND: There remains common belief in the general community that weight cycling or 'yo-yo dieting' is associated with potential adverse effects on obesity and metabolic risk factors. In 1994, a review by the National Task Force on the Prevention and Treatment of Obesity concluded that weight cycling did not impact metabolism, and that weight loss attempts should not be discouraged. This study is an updated review of the literature published since 1994, to determine if weight cycling is associated with metabolic risk factors for obesity and type 2 diabetes...
