Dietary macronutrient composition plays a critical role in health and disease. The contribution of dietary carbohydrate source in the development of obesity and related diseases is often given minimal attention. The present studies demonstrate that both quantitative and qualitative changes in dietary carbohydrate influence body composition and adiposity in a rodent model of diet-induced obesity. In heterozygous (fa/+) Zuker rats, consumption of a high-fat, carbohydrate free ad libitum, attenuated weight gain and adiposity by increasing energy efficiency and blunting expression of fatty acid synthase, a key enzyme in de novo lipogenesis. These effects were independent of significant …

An Evaluation Of Influences On Preadolescent Boys' Body Mass Index And Body Composition, Lynn Samson Brann
Doctoral Dissertations
This study was designed to investigate the differences in the diets, activity levels, body concerns, body esteem, and body perceptions of fifty preadolescent boys in relation to their body mass index (BMI; kg/m2) and their percent body fat (PBF), measured using air-displacement plethysmography. Additionally, it was designed to examine general parenting and child feeding practices of parents in relation to their sons' BMI and PBF. Boys were recruited based on their BMI and were placed into either an average BMI group or a high BMI group. Additionally, boys were placed into either a lower PBF group or an …
