AbstractThis paper reviews recent data concerning the role of inherited differences in body fat content. The heritability of percent body fat or fat mass reaches about 25% of the age and gender adjusted phenotypic variance. One study has reported a significant major gene effect accounting for almost one half of the variance in body fat content ...

ON BODY FAT AND BODY WATER IN RATS
Canadian Journal of Biochemistry and Physiology, 1955Under our experimental conditions, water represented 72% of the fat-free body mass. This constant was found to be completely independent of the magnitude of the fat depots. Consideration of the composition of various samples of adipose tissue suggests that the water to fat-free dry matter ratio is the same as in the body as a whole or that any "excess"

Body weight, body fat, and ovulation
Trends in Endocrinology & Metabolism, 1991Women with moderate weight loss (10%-15% of ideal weight) have secondary or primary amenorrhea. Athletic women also may have amenorrhea, or anovulatory cycles, though body weight may be in the normal range, since muscles are heavy (80% water compared with 5%-10% water in adipose tissue).

Dietary fat is not a major determinant of body fat
The American Journal of Medicine, 2002The percentage of energy from fat in diets has been thought to be an important determinant of body fat, and several mechanisms have been proposed. Comparisons of diets and the prevalence of obesity between affluent and poor countries have been used to support this relationship, but these contrasts are seriously confounded by differences in physical ...

Dietary fat and body fat: an intervention study.
International journal of obesity and related metabolic disorders : journal of the International Association for the Study of Obesity, 1996Assessment of body composition in relation to the habitual diet and after a six month dietary intervention.After a baseline measurement subjects were randomly assigned to either a group consuming reduced-fat products or a group consuming full-fat products for six months.108 women and 109 men, equally distributed over the age range 19-35 with BMI ...

Assessment of cutaneous fat and body fat by ultrasound
Klinische Wochenschrift, 1987A new rapid and simple method is introduced to measure subcutaneous fat and evaluate total body fat. It is based on real-time ultrasound and requires equipment that is used in routine examination of subcutaneous structures, e.g., thyroid gland. Results from seven regions of skin in 100 subjects correlated well with total body weight, Broca's index, and

Fat areas as estimates of total body fat
The American Journal of Clinical Nutrition, 1980The efficacy of cross-sectional fat areas in estimating total body fat was investigated in a sample of white American children and adults. Body density and total fat weight (kg) in the body were determined by hydrostatic weighing. Fat areas were calculated for the arm and calf using the appropriate limb circumferences and skinfolds measured at the ...

Measurement of body fat and hydration of the fat-free body in health and disease
Metabolism, 1985Body fat mass, fat-free body mass and body water are basic components of body composition which are used in nutritional and metabolic studies and in patient care. A method of measuring total body fat (TBF), fat-free mass (FFM) and its hydration (TBW/FFM) involving prompt gamma in vivo neutron activation analysis (IVNAA) and tritium dilution has been ...

Body fat, abdominal fat and body fat distribution related to VO2PEAKin young children
International Journal of Pediatric Obesity, 2011Aerobic fitness, defined as maximum oxygen uptake (VO(2PEAK)), and body fat measurements represent two known risk factors for disease. The purpose of this study was to investigate the relationship between VO(2PEAK) and body fat measurements in young children at a population-based level.Cross-sectional study of 225 children (128 boys and 97 girls) aged ...

Body mass index, body fat percentage, and the effect of body fat mass on SWL success
International Urology and Nephrology, 2007In the present study, we investigated the effects of the Body Mass Index (BMI), the Body Fat Percentage (BFP), and the Body Fat Mass (BFM) on success of SWL, prospectively.The BMI, BFP, BFM values of patients, who were treated by SWL due to upper urinary system stone disease (pelvis renalis, upper ureter, kidney lower and upper calices) between January
