Abstract
Excess body weight is a major global health concern, particularly due to its associated increased health risks. Several strategies have been proposed to prevent overweight and obesity onset. In the past decade, it has been suggested that eating speed/rate and eating frequency might be related to obesity. The main aim of this narrative review was to summarize existing evidence regarding the impact of eating speed/rate and eating frequency on adiposity, metabolic syndrome (MetS), or diet quality (DQ). For this purpose, a literature search of observational and interventional trials was conducted between June and September 2020 in PubMed and Web of Sciences databases, without any data filters and no limitations for publication date. Results suggest that children and adults with a faster eating speed/rate may be associated with a higher risk of developing adiposity, MetS or its components. Furthermore, a higher eating frequency could be associated with diet quality improvement, lower adiposity, and lower risk of developing MetS or its components. Further interventional trials are warranted to clarify the mechanism by which these eating behaviors might have a potential impact on health.

Abstract
Metabolic syndrome, whose main diagnostic component is obesity, is a risk factor for lifestyle-related diseases, type 2 diabetes, and cardiovascular disease. Diet is known to affect the prevalence of metabolic syndrome. However, the effect of diet on metabolic syndrome in Japanese subjects has not been thoroughly explored. In the present study, we investigated the effect of carotenoid-rich vegetables, particularly lycopene- and lutein-rich vegetables, on the metabolic syndrome in obese Japanese men. We conducted an 8-week long randomized, double-blinded, controlled clinical trial in which, 28 middle-aged (40 ≤ age < 65) Japanese men with high body mass index (BMI ≥ 25) were randomized into four dietary groups: high lycopene + high lutein (HLyHLu), high lycopene + low lutein (HLyLLu), low lycopene + high lutein (LLyHLu), and low lycopene + low lutein (LLyLLu). Our results showed that daily beverage-intake increased the plasma levels of carotenoids without adverse effects, and the visceral fat level was significantly decreased in all the groups. The waist circumference was significantly decreased only in the HLyLLu group, whereas the CoQ10 oxidation rate was decreased in all the groups. The gene expression profiles of whole blood samples before and after ingestion differed only in the LLyLLu group, indicating the effect of carotenoids on gene expression profile. In conclusion, our results suggest that dietary uptake of carotenoid-rich vegetables increases their concentration in blood and reduces the intra-abdominal visceral fat.

Abstract
Current algorithms for assessing risk of atherosclerotic cardiovascular disease (ASCVD) and, in particular, the reliance on low-density lipoprotein (LDL) cholesterol in conditions where this measurement is discordant with apoB and LDL-particle concentrations fail to identify a sizeable part of the population at high risk for adverse cardiovascular events. This results in missed opportunities for ASCVD prevention, most notably in those with metabolic syndrome, prediabetes, and diabetes. There is substantial evidence that accumulation of ectopic fat and associated metabolic traits are markers for and pathogenic components of high-risk atherosclerosis. Conceptually, the subset of advanced lesions in high-risk atherosclerosis that triggers vascular complications is closely related to a set of coordinated high-risk traits clustering around a distinct metabolic phenotype. A key feature of this phenotype is accumulation of ectopic fat, which, coupled with age-related muscle loss, creates a milieu conducive for the development of ASCVD atherogenic dyslipidemia, nonresolving inflammation, endothelial dysfunction, hyperinsulinemia, and impaired fibrinolysis. Sustained vascular inflammation, a hallmark of high-risk atherosclerosis, impairs plaque stabilization in this phenotype. This review describes how metabolic and inflammatory processes that are promoted in large measure by ectopic adiposity, as opposed to subcutaneous adipose tissue, relate to the pathogenesis of high-risk atherosclerosis. Clinical biomarkers indicative of these processes provide incremental information to standard risk factor algorithms and advanced lipid testing identifies atherogenic lipoprotein patterns that are below the discrimination level of standard lipid testing. This has the potential to enable improved identification of high-risk patients who are candidates for therapeutic interventions aimed at prevention of ASCVD.

Abstract
BACKGROUND & AIMS Excess adiposity is associated with poor cardiometabolic (CM) health. To date, several techniques and indicators have been developed to determine adiposity. We aimed to compare the ability of traditional anthropometric, as well as standard and novel DXA-derived parameters related to overall and regional adiposity, to evaluate CM risk. METHODS Using the cross-sectional design in the context of the PREDIMED-Plus trial, 1207 Caucasian senior men and women with overweight/obesity and metabolic syndrome (MetS) were assessed. At baseline, anthropometry- and DXA-measured parameters of central, visceral, peripheral and central-to-peripheral adiposity together with comprehensive set of CM risk factors were obtained. Partial correlations and areas under the ROC curve (AUC) were estimated to compare each adiposity measure with CM risk parameters, separately for men and women, and in the overall sample. RESULTS DXA-derived indicators, other than percentage of total body fat, showed stronger correlations (rho -0.172 to 0.206, p < 0.001) with CM risk than anthropometric indicators, after controlling for age, diabetes and medication use. In both sexes, DXA-derived visceral adipose tissue measures (VAT, VAT/Total fat, visceral-to-subcutaneous fat) together with lipodystrophy indicators (Trunk/Legs fat and Android/Gynoid fat) were strongly and positively correlated (p < 0.001) with glycated hemoglobin (HbA1c), the triglyceride and glucose index (TyG), triglycerides (TG), the ratio TG/HDL-cholesterol (TG/HDL-C), and were inversely related to HDL-C levels (p < 0.001). Furthermore, in AUC analyses for both sexes, VAT/Total fat showed the highest predictive ability for abnormal HbA1c levels (AUC = 0.629), VAT for TyG (AUC = 0.626), both lipodystrophy indicators for TG (AUCs = 0.556), and Trunk/Legs fat for HDL-C (AUC = 0.556) and TG/HDL-C (AUC = 0.581). CONCLUSIONS DXA regional adiposity measures offer advantages beyond traditional anthropometric and DXA overall adiposity indicators for CM risk assessment in senior overweight/obese subjects with MetS. In particular, in both sexes, visceral adiposity better stratifies individuals at risk for glucose abnormalities, and indicators of lipodystrophy better predict markers of dyslipidemia.

Abstract
BACKGROUND Obesity and overweight are major public health problem. Different-strategies have been developed for body contouring including Radiofrequency(RF) and Ultrasound(US). The aim of this study was to investigate changes in serum-leptin as a potential-modulator of food/energy intake, in overweight-women receiving RF/US and diet-therapy as well as the effect of therapy on modulation of lipid-profile and body-fat-mass. METHODS Fifty overweight-females were enrolled in current randomized-clinical-trial and randomly divided into two groups. The case group received RF/US twice a week for 5 weeks with a low calorie diet whilst the control-group received just a low calorie diet. Demographic, biochemical markers as well as serum-leptin were determined. RESULTS The level of leptin was reduced from 1.29 ± 0.32 ng/ml to 1.14 ± 0.34 ng/ml in case group, before and after therapy, respectively, whilst no significant differences were observed in the serum leptin levels of subjects in the control group. The combination of RF and US decreased the leptin-level. In particular, the mean reduction of abdominal-circumference and waist-circumference was significant (P < 0.05) after therapy. This reduction was inversely correlated with LDL levels. Weight was reduced in case and control groups and in both was significant, but no statistically significant differences were detected for weight between the groups(P < 0.93). CONCLUSION Our findings demonstrated the reduction of the leptin after treatment with the combination of Radiofrequency/Ultrasound cavitation, which was associated with reduced body-fat-mass.

The Effect of Low Glycemic Index and Glycemic Load Diets on Hepatic Fat Mass, Insulin Resistance, and Blood Lipid Panels in Individuals with Nonalcoholic Fatty Liver Disease.
Parker, A, Kim, Y
Metabolic syndrome and related disorders. 2019;(8):389-396
Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease that is associated with insulin resistance and hepatic triglyceride accumulation. There is evidence to suggest that a low glycemic index (GI) diet can reduce glucose absorption, hepatic influx of glucose, and de novo lipogenesis. This review investigates the effect of low GI and glycemic load (GL) diets on hepatic fat mass, hepatic enzymes, insulin resistance, fasting blood glucose levels, and blood lipid panels in individuals with NAFLD. PubMed, Cumulative Index to Nursing and Allied Health Literature, and Web of Science were used in literature search. Search keywords included "glycemic index," "glycaemic index," "glycemic load," "glycaemic load," "nonalcoholic fatty liver disease," "NAFLD," "nonalcoholic steatohepatitis," and "NASH." Outcome measurements included hepatic fat mass, hepatic enzyme alanine transaminase (ALT), insulin resistance [homeostasis model assessment of insulin resistance (HOMA-IR)], fasting blood glucose levels, and/or blood lipid panels. Four eligible studies enrolling 281 individuals with NAFLD were included. Both hepatic fat mass and ALT showed significant reductions from baseline in both low GI and GL diets. One study showed no change, and another study showed significant reductions in HOMA-IR. No significant reduction in fasting blood glucose level, triglycerides, high-density lipoprotein-cholesterol, or low-density lipoprotein-cholesterol was observed from baseline in both low GI and GL diets. Findings from the review suggest that low GI and GL diets may reduce hepatic fat mass and ALT in individuals with NAFLD. Future research of large-scale, randomized controlled studies using isoenergetic, low GI and GL diets for long term is needed to draw conclusionary results.

From inflammation to sexual dysfunctions: a journey through diabetes, obesity, and metabolic syndrome.
Maiorino, MI, Bellastella, G, Giugliano, D, Esposito, K
Journal of endocrinological investigation. 2018;(11):1249-1258
Abstract
Metabolic diseases are associated with chronic low-grade inflammation, which has been indicated as a potential mediator of endothelial dysfunction and cardiovascular disease. Visceral adiposity is thought to be the starting condition of the inflammatory state through the release of inflammatory cytokines, including TNF-alpha, CRP, and IL-6, which in turn promote endothelial dysfunction, endothelial expression of chemokines (IL-1) and adhesion molecules (ICAM-1, VCAM-1, and P-selectin), and the inhibition of anti-atherogenic factors (adiponectin). Obesity, metabolic diseases, and diabetes, all conditions characterized by abdominal fat, are well-recognized risk factors for sexual dysfunction in both sexes. Evidence from randomized-controlled trials supports the association between inflammatory milieau and erectile dysfunction in men suffering from metabolic diseases, whereas, in women, this has to be confirmed in further studies. A healthy lifestyle based on dietary pattern with high content of whole grain, fruit, nuts and seeds, and vegetables and low in sodium and saturated fatty acids plus regular physical activity may help to modulate the pro-inflammatory state associated with metabolic diseases and the related burden of sexual dysfunctions.

Abstract
PURPOSE Craniopharyngioma is associated with metabolic alterations leading to increased cardiovascular mortality. Recently, the visceral adiposity index has been proposed as a marker of visceral adipose tissue dysfunction and of the related cardiometabolic risk. The role of the visceral adiposity index has never been explored in craniopharyngioma patients. We assessed the cardiometabolic risk on the basis of the visceral adiposity index in craniopharyngioma patients. METHODS We evaluated data of 24 patients treated for craniopharyngioma in a single-centre. We investigated the relationship among patients' clinical and biochemical features, cardiovascular risk -assessed by the Framingham and the atherosclerotic cardiovascular disease risk scores-, visceral adiposity index and adipose tissue dysfunction severity. RESULTS Increased visceral adiposity index was found in 8 patients (33%). Adipose tissue dysfunction resulted to be severe, moderate or mild in 5, 2 and 1 cases. Increased visceral adiposity index significantly correlated with the occurrence of metabolic syndrome (p 0.027), IRI (p 0.001), triglycerides (p < 0.001), HOMA-IR (p < 0.001) and with lower ISI-Matsuda (p 0.005) and HDL-cholesterol (p < 0.001). Higher degree of adipose tissue dysfunction associated with increased insulin resistance. No gender difference was found for visceral adiposity index, adipose tissue dysfunction severity, and cardiovascular risk scores. Patients with adulthood onset craniopharyngioma showed higher Framingham risk score (p 0.004), atherosclerotic cardiovascular disease 10-year (p < 0.001) and lifetime (p 0.018) risk scores than those with childhood onset disease. CONCLUSIONS Visceral adiposity index is increased in one third of our patients with craniopharyngioma, even if metabolic syndrome does not occur. Increased visceral adiposity index and adipose tissue dysfunction severity correlate with insulin sensitivity parameters, do not correlate with Framingham or atherosclerotic cardiovascular disease risk scores, and are not influenced by gender and age of disease onset.

Abstract
Sodium intake was reported to be related to metabolic syndrome (MS). Although a strong association between sodium intake and blood pressure (BP) has been reported, the relationship between sodium intake and other components of MS is unknown. An observational study of 18,146 adults in the Korea National Health and Nutrition Examination Survey IV-V databases (2008-2011) was performed. Estimates of 24-h sodium excretion were made from a single fasting urine sample. A significant positive association was found between sodium excretion and systolic BP and between sodium excretion and diastolic BP in participants with and without hypertension after adjusting for multiple covariates (P < 0.001 for trend). The relationship between triglyceride or glucose levels and sodium excretion was linear (P < 0.005). In both men and women, a positive relationship between sodium excretion and waist circumference and an inverse relationship between sodium excretion and high-density lipoprotein were found (P ≤ 0.001). Body fat percentage, body fat mass, and insulin level were positively related to sodium excretion (P ≤ 0.001), and HOMA-IR was significantly associated with sodium excretion (P < 0.05). The risk of MS was elevated 1.279-fold in the second quartile of sodium excretion (95% CI, 1.088-1.504, P = 0.003), 1.479-fold in the third quartile (95% CI, 1.262-1.734; P < 0.001), and 1.929-fold in the highest quartile (95% CI 1.654-2.249, P < .001) compared with the lowest quartile. Sodium intake is significantly associated with all components of MS, body fat, and insulin resistance. Therefore, a high-salt diet is a significant risk factor for MS.

Development of whole body adiposity in preterm infants.
Griffin, IJ, Cooke, RJ
Early human development. 2012;:S19-24
Abstract
The long-term effects of prematurity, early diet and catch-up growth on metabolic risk and body adiposity are of increasing interest to Neonatologists. Poor growth is known to be associated with poorer neuro-developmental outcome but concern exists that increased rates of "catch-up" (or "recovery") growth may be associated with increased adiposity and the later development of metabolic syndrome. In this manuscript we review the published data on body composition in preterm infants, and present new analyses of body adiposity in preterm infants during the 12-15 months of life, and the effect of growth rate (weight gain) on body adiposity. We conclude that although preterm infants have increased adiposity at term corrected age, they generally have lower body fat than their term peers during the rest of the 12-15 months of life. Although more rapid "catch-up" growth in preterm infants during the first year of life is associated with greater body fatness than slower rates of growth, these higher rates of growth lead to body composition more similar to that of the term-born infant, than do slower rates of growth. Although more studies are needed to determine whether these short-term increases or the longer-term decreases in adiposity modify the risk on chronic diseases such as diabetes mellitus, hypertension or other components of the metabolic syndrome, the widely held concern that preterm babies have greater adiposity than their term peers, and that this is worsened by greater amounts of catch-up growth, are not supported by the available evidence.
