Resistant Starch And Sodium Butyrate Reduce Body Fat In Rodents, Kirk Adam Vidrine
Resistant Starch And Sodium Butyrate Reduce Body Fat In Rodents, Kirk Adam Vidrine
LSU Master's Theses
Introduction: Obesity levels in the United States have significantly increased in the last forty years. Lifestyle and pharmacological treatments have been largely ineffective in treating obesity for most people. Both Resistant Starch (RS) and Dietary Sodium Butyrate (SB) are bioactivties which have shown the ability to decrease body fat levels of rodents without increasing physical activity or decreasing energy intake. Glucagon-like peptide 1 (GLP-1) and peptide YY (PYY) are gut hormones that may be involved in increased energy expenditure at a cellular level with dietary RS and SB. Objective: To discern if SB and RS both work through the increase …
The Impact Of Self-Reported Physical Activity Levels On The Prediction Of Body Fatness From Bmi In White And Black College Students, Michael Zanovec
The Impact Of Self-Reported Physical Activity Levels On The Prediction Of Body Fatness From Bmi In White And Black College Students, Michael Zanovec
LSU Master's Theses
The purpose of this study was to test the hypothesis that self-reported physical activity (PA) levels quantified from the International Physical Activity Questionnaire (IPAQ) could be used to improve the prediction of percent body fat (%BF) measured by dual-energy X-ray absorptiometry (DXA) from body mass index (BMI), gender, and race in White and Black college students. A total of 278 students, aged 18 – 24 yr, volunteered to participate. There were 133 males (85 White and 48 Black) and 145 females (77 White and 68 Black). Total activity levels were quantified in MET-hours per week (MET-hrs•wk-1) using the IPAQ short …
Resistant Starch Does Not Reduce Body Fat In Rats Fed A High Fat Diet, Sasmita Tripathy
Resistant Starch Does Not Reduce Body Fat In Rats Fed A High Fat Diet, Sasmita Tripathy
LSU Master's Theses
This study examined the effects of resistant starch in a high fat diet (28% of energy) on body weight, abdominal fat, cecal weight and pH, serum gut peptide YY (PYY) and gene expression for PYY and proglucagon in male Sprague Dawley rats. Three groups of rats (8wk) were fed one of the following diets for ten wks: energy control (EC; 3.7 kcal/g), resistant starch (RS; 3.7 kcal/g) and fiber control (FC; 2.9 kcal/g). Results were classified as significant when p<0.05. The consumption of RS resulted in significant increases in cecal weight (full and empty), serum PYY, gene expression for PYY and proglucagon in cecum and significant decrease in pH in cecal contents compared to the other groups. However, the disemboweled body weight and abdominal fat for RS were not lower compared to the EC. In our previous studies, we observed that RS in a low fat diet (18% of energy), produced similar gut signaling, as in the current study, but reduced disemboweled body weight and abdominal fat compared to EC. The reason for the unexpected results needs further study. Since high fat diets have been shown to alter brain response to other satiety signals (leptin), a high fat diet might affect neuronal responses to PYY and GLP-1 signaling from the gut caused by dietary RS.
