Effects of Visceral Fat Accumulation Awareness on a Web-Based Weight-Loss Program: Japanese Study of Visceral Adiposity and Lifestyle Information—Utilization and Evaluation (J-VALUE)

Abstract

A reduction of visceral fat is important for improvement of metabolic risk. This study was designed to compare the effects of a web-based program alone or together with measurement and self-awareness of accumulated visceral fat in Japanese workers. A new noninvasive device to measure visceral fat accumulation was introduced, and efficacy on weight-loss and improvement of healthy behaviors were examined. This study was conducted according to Helsinki declaration and approved by the ethical committee of Japan Hospital Organization, National Kyoto Hospital. Two-hundred and sixteen overweight and obese males with BMI of more than 23 participated from 8 healthcare offices of 3 Japanese private companies. Subjects were randomly allocated into control group, Web-based weight-loss program (Web), or Web + Visceral fat measurement group (Web + VFA). Eighty-one percent of participants completed the study. Reductions of body weight, waist circumference, and BMI were the largest in Web + VFA group, and the differences between groups were significant by ANOVA. Improvements of healthy behaviors were the largest in Web + VFA group, and the differences of healthy eating improvement scores between Web + VFA and control groups were significant. Our findings suggest that measurement and awareness of visceral fat are effective in weight reduction in overweight and obese males in the workplace.

Hypolipidemic and Hypoglycaemic Effect of Wholemeal Bread with Amaranth (Amaranthus dubius Mart. ex Thell.) on Sprague Dawley Rats

“…The zoometric parameters are mostly used to evaluate the degree of obesity are AC and BMI, which have been associated with the risk of cardiovascular diseases [60], and mortality in patients with type 2 diabetes [61], although these are rarely assessed in assays with rats. The AC decreased in ABD10(E) and ABD20(E) rats after 8 weeks of consumption of the these diets including A. dubius, which is a relevant indicator of the reduction in visceral fat, which at the same time reduces the risk of metabolic syndrome [62], possibly influenced by the high fibre content in A. dubius [24,42,63]. It is well known that fibre increases satiety and reduces intestinal transit time and glycaemic response.…”

The Effectiveness of Physical Activity-Promoting Web- and Mobile-Based Distance Weight Loss Interventions on Body Composition in Rehabilitation Settings: Systematic Review, Meta-analysis, and Meta-Regression Analysis

“…Among the 30 included studies, the outcome variable was BMI in 19 (63%) studies [64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82], waist circumference in 25 (83%) studies [64,66,[68][69][70][71][72][73][74][75][76][78][79][80][81][82][83][84][85][86][87][88][89][90][91], and body fat percentage in 11 (37%) studies [64,70,72,73,76,78,80,…”

“…The mean age of the participants was 40.2 (SD 17.1) years. In a study by Sakane et al [79], the average age was not reported, but the age range of the participants was used. Therefore, the average age was imputed from the average age of Japanese people aged 20-65 years [94], weighted with the proportions of men and women in the study.…”

“…The mean duration of the interventions was 30.4 weeks (SD 17.9; range 4 weeks to 2 years). In the included studies, weight loss was set as the main aim of the study in 60% (18/30) of the studies [64,66,68,[71][72][73][74][76][77][78][79][80][81][82]85,86,89,91]. Of the 30 included studies, 3 (10%) aimed to increase the level of physical activity [70,88,92], whereas 2 (7%) focused on both increasing the participants' physical activity and decreasing their weight [84,93].…”

Computational method for estimating boundary of abdominal subcutaneous fat for absolute electrical impedance tomography

“…However, these devices simply output an estimated square measure of the visceral fat area (VFA). It would be desireble to obtain a more visually persuasive output, which would strongly motivate the patient to modify his/her lifestyle and reduce visceral fat accumulation by exercising and changing his/her dietary habits …”
