Stress And Eating Behaviors: A Systematic Review, Jessica L. Sieber

Masters Theses

Background: The effects of psychological stress on eating behaviors either through psychological/social influences (i.e. comfort foods, learned behaviors) or psychoneuroendocrine pathways have been studied for many years; however, a review of current research is lacking. The purpose of this study is to conduct a systematic literature review of the relationship between stress and eating behaviors with a concentration on how stress and eating behaviors are measured.

Methods: PubMed and PsycINFO databases were searched to identify peer-reviewed English-language human studies published between 1966 and March 2006. Keywords and subject headings used were: stress, eating, feeding behaviors, food habits, energy intake, diet, …

Home Grocery Delivery Improves The Household Food Environments Of Behavioral Weight Loss Participants: Results Of An 8-Week Pilot Study, Amy A. Gorin, Hollie A. Raynor, Heather M. Niemeier, Rena R. Wing

Nutrition Publications and Other Works

Background

Household food availability is consistently linked to dietary intake; yet behavioral weight control treatment includes only minimal instruction on how to change the home environment to support dietary goals. This pilot study examined whether it is feasible to change the household food environments of behavioral weight loss participants through the use of a commercially available grocery home delivery service.

Methods

Overweight participants (N = 28; BMI = 31.7 ± 3.6 kg/m²; 89.3% women, 47.9 ± 9.5 years) were randomly assigned to 8-weeks of standard behavioral weight loss (SBT) or to SBT plus home food delivery (SBT+Home). SBT+Home …

Liver Lipid Molecules Induce Pepck-C Gene Transcription And Attenuate Insulin Action., Guoxun Chen

Nutrition Publications and Other Works

Cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C) plays key roles in gluconeogenesis, glyceroneogenesis, and cataplerosis. Experiments were designed to examine the effects of endogenous lipid molecules from rat livers on the expression of PEPCK-C gene in primary rat hepatocytes. The lipid extracts prepared from livers of Zucker fatty, lean, and Wistar rats induced the expression levels of PEPCK-C transcripts. Insulin-mediated reduction of PEPCK-C gene expression was attenuated by the same treatment. The lipid extracts induced the relative luciferase activity of reporter gene constructs that contain a 2.2-kb 5' promoter fragment of PEPCK-C gene, but not the construct that contains only the 3' untranslated …

An Examination Of The Education, Credentials, And Functions Of School Food Service Directors In Tennessee Public School Districts, Elizabeth T. Anderson

Masters Theses

Childhood overweight and the associated health consequences have become a significant health problem in the United States and particularly in the state of Tennessee, with 14.8% of U.S. and 20.0% of Tennessee youth’s aged 10-17 currently classified as being overweight (1). Environmental factors play a significant role in the etiology of overweight, and therefore need to be considered in efforts undertaken to address this problem. Schools are one such environment where U.S. children spend a great deal of time, making the school food environment, which includes all foods available in schools (such as foods served in the school meals, a …

Calcium, Angiotensin Converting Enzyme Inhibitors, And Branched Chain Amino Acids Contribute To The Anti-Obesity Effects Of Milk, Anna C. Herweyer

Masters Theses

Dietary calcium exerts an anti-obesity effect, and dairy exerts about twice the activity as supplemental calcium. Milk contains angiotensin converting enzyme inhibitors (ACEi) and a high concentration of branched chain amino acids (BCAA), both of which may contribute to an anti-obesity effect through effects on lipid metabolism and muscle protein synthesis, respectively. To test this hypothesis, aP2-agouti transgenic mice were maintained for 6 weeks on an obesigenic soy based diet and then randomized into an ad libitum control group and energy restricted (70% of ad lib) diets containing soy protein (0.4% Ca), non-fat dry milk (NFDM; 1.2% Ca) or …
