Obesity is an ongoing global pandemic that affects more than one in three adults in the United States. Being overweight or obese also increases the risk of chronic health conditions. Weight management does not only center on immediate weight loss but also on the proper maintenance of an appropriate body weight over the years. Methods of weight management include eating a healthy diet and meeting physical activity guidelines. Such weight management practices are important to ensure that the people suffering from obesity can decrease risks of morbidity or even mortality. Nevertheless, unhealthy weight management strategies might lead to unintended health consequences. A healthy eating plan and regular physical activity will aid in weight maintenance. However, other related aspects need to be considered as well to design effective weight management interventions. Therefore, the purpose of this dissertation is to discover relatively unexplored weight management related factors to help advance our knowledge in this area and to open new frontiers for research. This dissertation walks through a body of unexplored translational research work related to weight management that contributes to the ever-growing field of obesity prevention. The dissertation utilizes data from USDA GetFRUVED project and Sanford Successful Weight Management project. Research has shown the need for improved dietary behaviors among young adults. The dietary habits among young adults were explored to determine if there is an association with farmers’ market use utilizing the National Cancer Institute (NCI) fruit vegetable intake screener, and National Institute of Health (NIH) dietary intake screener. Of the known influences on Physical activity levels, the Physical activity perceptions are the least understood area. The Physical activity levels and its perceived benefits and barriers were explored using International Physical Activity Questionnaire (IPAQ) algorithm scores and Exercise Benefit Barrier Scales (EBBS). Further, body composition changes that vary with age and weight change are of concern, especially among older adults. The studies reporting such changes in elderly participating in commercial weight management programs were explored using PUBMED. Together the findings from this dissertation will help to design more precise weight management interventions than what currently exists to combat the obesity pandemic.
