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.

Time restricted eating (TRE) is an increasingly popular diet strategy that has shown promise for weight loss and improving metabolic health. The impact of TRE on bone health has not been extensively studied, and the goal of this experiment is to provide more insight into this subject. 32 10-week old female mice were randomly assigned to 4 groups (n = 8). These included low fat diet fed ad-libitum, low fat time restricted feeding (TRF), high fat diet fed ad-libitum, and high fat TRF. The mice adhered to these diets for 9 weeks, with the TRF groups having access to food for 8 hours per day until the sacrifice. At nine weeks, the TRF mice had significantly lowered body weight, improved body composition, and a lower fasting blood glucose. The TRF groups also experienced significant improvements in the trabecular bone density of the tibia, femur, and L3 vertebral body. This was found alongside reductions in osteoclast count and activity in the TRF mice. When compared to a baseline group of 10-week old mice, it was found that the TRF group had significantly less bone loss relative to the ad-libitum fed mice. Improvements in metabolic health, gut barrier function, and inflammation may have all contributed to the observed improvements in bone health. These results reveal a promising and previously unrecognized dietary tool to improve bone health and counteract age-related bone loss.
