Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

The Effect of Early Time-Restricted Feeding on the Diet Quality, Self-Efficacy, and Sleep of College Students

Description

Circadian misalignments in terms of eat and sleep cycles, common occurrences among college students, are linked to adverse health outcomes.

Circadian misalignments in terms of eat and sleep cycles, common occurrences among college students, are linked to adverse health outcomes. Time-restricted feeding, a form of intermittent fasting, may offer an exciting, non-pharmacologic approach to improve the health of this population by restricting eating to feeding windows that align with circadian biology. This study aims to fill a gap in the literature regarding the effect of early time-restricted feeding (eTRF) on college students, particularly in regard to diet quality, diet self-efficacy, and sleep quality. To test the hypothesis that eTRF would lead to an increase in all three variables, a 4-wk randomized-controlled, parallel arm trial was conducted. Thirty-five healthy college students were randomly assigned to one of two groups: the intervention group (TRF) was instructed to adhere to an 8-h feeding window aligned with the light cycle (9 am to 5 pm), and the control group (CON) was instructed to adhere to a 12-h feeding window typical of college students (10 am to 10pm). The eTRF diet was consumed ad libitum, and the participants were not instructed to avoid compensatory hyperphagia. The results showed a strong, reverse effect of eTRF on diet quality: fasting had a highly significant association with decreased diet quality. The results suggest that, under free-living conditions, college students practicing eTRF are more likely to compensate for prolonged fasting with unhealthy eating and snacking.

Energy Expenditure: Relationships Between Ghrelin And Body Composition In Healthy Young Men

Ghrelin is an acylated peptide hormone with far reaching affects within the human body. Consisting of both central and peripheral effects, ghrelin has been the topic of research since its discovery in 1999. These effects include energy maintenance, cardiovascular health, growth hormone mediation, glucose homeostasis, muscle growth and atrophy, and bone metabolism, all of which work in concert with other well-known physiological mechanisms. With the goal to reproduce a similar study done in females in males, this study hypothesized that ghrelin would present an inverse relationship with a young healthy male population's resting metabolic rates. The study consisted of taking resting metabolic rate measurements, dual-energy X-ray absorptiometry, blood ghrelin testing, and statistical analysis of the data. The hypothesis was shown to be incorrect as the data showed a positive correlation, albeit, with very low statistical significance. Despite the data, past research has shown ghrelin plays a major role in fat gain, fat loss, and energy expenditure. Obesity is plaguing the world and becoming a major pubic health concern. It is necessary to explore causality and casual relationships in order to better understand and combat obesity. Therefore, further research is warranted into ghrelin and energy expenditure as a biomarker or novel treatment for obesity.
