Background: In addition to reducing body weight, the low-calorie diets can reduce the lean body mass. It is hypothesized that in addition to reducing the body weight, the low-calorie diets can maintain the lean body mass. So, the current study aimed at evaluating the effects of high-protein diet with calorie restriction on body composition in overweight and obese individuals. Methods: 36 obese ...

the aim of the present study was to examine the effect of aerobic training and green tea supplementation on serum leptin and insulin resistance in overweight and obese men. for this purpose, 43 overweight and obese men were selected voluntarily and were included in four groups: control (body mass index 31.4+3.7, vo2max 39.3+3.8 ml/kg.min), green tea supplement (body mass index, 30.3±2.8 k/m2, v...

Background and Objectives: Although a growing interest on the role of self-efficacy in weight management is reported worldwide, less research has been carried out on this association in adolescents. The aim of the present study was to investigate association of weight linked self-efficacy with anthropometric measurements in Tehrani male adolescents. Materials and Methods: The study was carried...

Obesity is associated with alterations in the vitamin D endocrine system. Lower levels of serum 25-hydroxyvitamin D (25-OHD) in morbidly obese individuals may be secondary to an alteration in tissue distribution resulting from an increase in adipose mass. Therefore, morbidly obese individuals are expected to need higher doses of vitamin D supplementation than the general population. However, it...

BACKGROUND Maternal polyunsaturated fatty acid (PUFA) concentrations during pregnancy may have persistent effects on growth and adiposity in the offspring. A suboptimal maternal diet during pregnancy might lead to fetal cardiometabolic adaptations with persistent consequences in the offspring. OBJECTIVE We examined the associations of maternal PUFA concentrations during pregnancy with childho...

Correlated responses in whole-body composition were determined in 12-wk-old male mice from replicate lines selected for 12 generations for high (HF) or low (LF) epididymal fat pad weight as a percentage of body weight (EPID) and high (HL) or low (LL) hind carcass weight as a percentage of body weight. The HF and LF lines diverged (P less than .01) in body fat percentage (FAT) and subcutaneous d...

AIMS (1) To validate a leg to leg bioimpedance analysis (BIA) device in the measurement of body composition in children by assessment of its agreement with dual energy x ray absorptiometry (DXA) and its repeatability. (2) To establish a reference range of percentage body fat in Hong Kong Chinese children. METHODS Sequential BIA and DXA methods were used to determine body composition in 49 chi...

Anthropometrie measures Body mass index When we speak about the prevalence of obesity in populations, we mean the fraction of people who have excess storage of body fat. ln adult men with weight in the acceptable range, the percentage of body fat is around 15-20%. ln women, this percentage is higher (about 25-30%). Because differences in weight between individuals are only partly due to variati...

Body mass index (BMI) is commonly used to identify obesity. In this study, we determined how accurately BMI could determine body composition and identify obese from non-obese individuals. Fat-free mass and body fat were determined with bioelectrical impedance. Adiposity was calculated as body fat per body mass and as body fat divided by body height (m2). Obesity was defined as a BMI of at least...
