Book Description
Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.

Book Description
The fact that about 30-40% of the adults in the Western world are overweight or obese testifies to the frequency of the disturbances in body weight regulation. Scientists have established that caloric intake, macronutrient composition of the diet, basal and resting metabolic rate, thermic response to food, energy expenditure associated with movement and physical activity, and preferential storage of the surplus of calories as fat or lean tissues are critical determinants of energy balance and body weight. While much has been learned, the field is poised for major advances with the advent of a variety of imaging techniques, progress in quantitative and molecular genetics, use of transgenic rodent models and of breeding experiments with informative inbred strains, availability of stable isotopes for metabolic and behavioral studies, and a growing number of useful experimental animal and human models. This volume takes an integrative approach to obesity. It is structured around four major topics: (1) the animal and human models currently available for the study of body weight regulation with their strengths and limitations, (2) the molecular and genetic basis of the regulation of body weight, (3) the metabolic and physiological mechanisms involved, and (4) the behavioral and social determinants. The 13 background papers provide a critical overview of the present knowledge base while the group reports summarize the extensive deliberations of 38 international experts. Particular emphasis has been given to promising research areas and on the advances needed to ensure a better understanding of the biological and behavioral mechanisms of the regulation of body weight, with a particular emphasis on overweight and obesity.

Book Description
Obesity is a growing epidemic with no consensus regarding solutions. Thirty healthy overweight and obese female subjects (41.9 " 12 years, 166 cm " 7 cm, a 100.5 kg " 19.6 kg, 46.0% " 4.0% body fat, and BMI 37.4 " 6.9) participated in the study. A 14-day dietary intervention examined acute effects of energy balance and macronutrient type on dietary intake, REE, body weight, body composition, and thyroid panel. Significant changes occurred in weight loss over time (p

Pregnancy-Induced Changes in Body Fat, Physical Fitness and Energy Requirements in Military and Civilian Women

Category : Body composition
Languages : en
Pages : 47
Book Description
This study addresses the impact of pregnancy-induced changes in body composition and physical fitness on postpartum return to duty readiness. We hypothesize that moderate levels of physical activity will maintain physical fitness and limit excess fat deposition during pregnancy without jeopardizing fetal growth if dietary intake is not restricted. Furthermore, moderate levels of physical activity will facilitate fat mobilization and conserve fat-free-mass (FFM) during postpartum weight loss. Physical activity, weight, FFM and fat mass, fitness, strength, and iron status will be measured in women with low to high pre-pregnancy BMI through a complete reproductive cycle (0, 8, 22, 36 wk gestation; 2, 6 and 24 wk postpartum). Physical activity will be quantified as the difference between total energy expenditure and basal metabolic rate measured by the doubly-labeled water method and room respiration calorimetry. Body volume (hydrodensitometry), total body water (2%(18o dilution), potassium (40K counting), nitrogen (prompt gamma activation), and bone mineral (dual X-ray absorptiometry) will be used to calculate FFM and fat mass. Physical fitness will be determined by submaximal and maximal aerobic capacity tests. This report presents preliminary results on women prior to, during and after pregnancy. Data obtained prior to pregnancy strongly indicate a need to revise military equations used to predict body fat of women. 14. SUBJECT TERMS IS. NUMBER OF PAGES.
