Introduction. The presence of excess fat in the abdomen, out of proportion to total body fat, is associated with increased risk for cardiovascular and metabolic diseases and other complications of obesity. Histoanatomical characteristics of the abdominal adipose tissue In regard to subcutaneous fat, accumulation of visceral abdominal adipose tissue is more associated with increased metabolic risk. However, mean have more visceral fat than pre-menopausal women. Compared with pre-menopausal women, postmenopausal women have 49% more intraabdominal fat, regardless of age and total fat mass. Measurement of abdominal fat depots Various anthropometric indicators have been suggested for measuring body fat distribution. All of them have advantages and disadvantages, in relation to their interpretation and use. Many are specified as ratios and are difficult to interpret biologically, whereas a change in body fat distribution may exhibit little or no change in the ratios. Waist circumference and sagittal abdominal diameter are good predictors of visceral fat. But, extreme individual variations in visceral to subcutaneous ratio demonstrate the limitations of external anthropometry. The best methods to estimate the amount of visceral fat are imaging techniques like computed tomography or magnetic resonance, but they are expensive and inconvinient in routine practice. Conclusion. Further investigations should provide a simple and optimal indicator of abdominal obesity which should correlate with the amount of viscelar fat and the risk. .

Preferential accumulation of fat in the gluteo-femoral (GF) depot (pear shape) rather than in the abdominal (A) depot (apple shape), protects against the development of metabolic diseases but the underlying molecular mechanism is still unknown. Recent data, including our work, suggest that differential epigenetic marking is associated with regulation of genes attributed to distinct fat distribution. Here, we aimed to compare the genomic DNA methylation signatures between apple and pear-shaped premenopausal women. To investigate the contribution of upper and lower body fat, we used paired samples of A-FAT and GF-FAT, analyzed on the BeadChip Methylation Array and quantified the differentially methylated sites between the 2 groups of women. We found unique DNA methylation patterns within both fat depots that are significantly different depending on the body fat distribution. Around 60% of the body shape specific DNA methylation sites identified in adipose tissue are maintained ex vivo in cultured preadipocytes. As it has been reported before in other cell types, we found only a hand full of genes showing coordinated differential methylation and expression levels. Finally, we determined that more than 50% of the body shape specific DNA methylation sites could also be detected in whole blood derived DNA. These data reveal a strong DNA methylation program associated with adipose tissue distribution with the possibility that a simple blood test could be used as a predictive diagnostic indicator of young women who are at increased risk for progressing to the apple body shape with a higher risk of developing obesity related complications.Clinical Trial Registration:https://clinicaltrials.gov/ct2/show/NCT02728635 and https://clinicaltrials.gov/ct2/show/NCT02226640, identifiers NCT02728635 and NCT02226640.

Body fat distribution, especially visceral fat accumulation, may contribute more than total fat mass per se to the development of metabolic and cardiovascular disorders. Early prevention highly improves health outcomes later in life, especially when considering such cumulative conditions as atherosclerosis. However, as these processes emerge to be partly reversible, dietary and lifestyle interventions at any age and health condition are greatly beneficial. Given the worldwide abundance of metabolic and cardiovascular disorders, the identification and implementation of strategies for preventing or reducing the accumulation of morbid fat tissues is of great importance for preventing and regressing atherosclerosis. This review focuses on dietary strategies and specific food components that were demonstrated to alter body fat distribution and regression of atherosclerosis. Different properties of various adipose depots (superficial subcutaneous, deep subcutaneous and visceral fat depots) and their contribution to metabolic and cardiovascular disorders are briefly discussed. Visceral obesity and atherosclerosis should be approached as modifiable rather than ineluctable conditions.

Abstract Background: The relationship between betatrophin/ANGPTL8 and obesity has been investigated using body mass index (BMI); however, since BMI reflects overall adiposity rather than body fat distribution, it remains unclear whether fat deposition in different areas of the body affects betatrophin expression. Here, we investigated the correlation between circulating betatrophin levels and body fat distribution in patients with different glucose tolerance. Methods: In 128 participants with impaired glucose tolerance (IGT; n = 64) or normal glucose tolerance (NGT; n = 64), we measured circulating betatrophin levels by enzyme-linked immunosorbent assay and body fat distribution (subcutaneous, visceral, and limb fat) using magnetic resonance imaging (MRI) and a body fat meter. Results: After controlling for age, sex, and BMI, betatrophin was correlated positively with visceral adipose tissue-to-subcutaneous adipose tissue ratio ( VAT/SAT ratio; r = 0.339, p = 0.009) and negatively with body fat ratio (BFR; r = -0.275, p = 0.035), left lower limb fat ratio (LLR; r = -0.330, p = 0.011), and right lower limb fat ratio (RLR; r = -0.288, p = 0.027) in the NGT group, with these correlations remaining after controlling for triglycerides. VAT/SAT ratio (standardized β = 0.419, p = 0.001) was independently associated with serum betatrophin levels; however, betatrophin was not associated with body fat distribution variables in the IGT group. Conclusions: Circulating betatrophin levels correlated positively with VAT/SAT ratio and negatively with lower limb fat, but not subcutaneous or upper limb fat, in individuals with normal glucose tolerance. Thus, betatrophin may be a poten­tial biomarker for body fat distribution in individuals without glucose disorders.

The accumulation of visceral fat is independently associated with an increased risk for cardiovascular disease. The aim of this study was to determine whether the loss of visceral adipose tissue area (VAT; computed tomography) is related to improvements in maximal O2 uptake (V˙o 2 max) during a weight loss (250–350 kcal/day deficit) and walking (3 days/wk, 30–40 min) intervention. Forty obese [body fat 47 ± 1 (SE) %], sedentary (V˙o 2 max 19 ± 1 ml · kg−1 · min−1) postmenopausal women (age 62 ± 1 yr) participated in the study. The intervention resulted in significant declines in body weight (−8%), total fat mass (dual-energy X-ray absorptiometry; −17%), VAT (−17%), and subcutaneous adipose tissue area (−17%) with no change in lean body mass (all P < 0.001). Women with an average 10% increase in V˙o 2 max reduced VAT by an average of 20%, whereas those who did not increaseV˙o 2 max decreased VAT by only 10%, despite comparable reductions in body fat, fat mass, and subcutaneous adipose tissue area. The decrease in VAT was independently related to the change in V˙o 2 max( r 2 = 0.22; P < 0.01) and fat mass ( r 2 = 0.08; P = 0.05). These data indicate that greater improvements inV˙o 2 max with weight loss and walking are associated with greater reductions in visceral adiposity in obese postmenopausal women.
