The purpose of this study is to develop and test the feasibility of a behavioral weight loss intervention that uses personalized recommendations for diet and physical activity behaviors in a behavioral weight loss program and to explore factors associated with treatment adherence and response. The 12-week intervention will utilize digital tools for self-monitoring and counseling by weight management professionals. Exploratory analyses will be conducted to determine if there are genetic, metabolomic, microbiome, or psychosocial factors associated with treatment response.
The primary objective of the study is to test a personalized approach for prescribing weight loss strategies in overweight adults participating in a weight loss intervention and to determine if a personalized approach can optimize weight loss compared to a standard behavioral weight loss intervention. Thus, all participants will receive a behavioral weight loss intervention delivered via remote counseling and digital tools including a smart phone app, Wi-Fi- enabled smart scale, physical activity tracker. Participants in the personalized group will also use a continuous blood glucose monitoring (CGM) device.
The differences between the two groups will be the approach used to recommend diet and physical activity changes. The study will compare a Standard Behavioral Weight Loss (BWL) approach tested in numerous previous studies and consistent with current clinical practice, to a Personalized Behavioral Weight Loss (PBWL) approach that tests a combination of diet and physical activity prescriptions to determine the best "fit" for the participant. The PWBL group will actively use CGM information during the intervention period to inform diet and activity behaviors. Participants will be randomized in a 3:1 ratio to PBWL or BWL (i.e., 30 to PBWL and 10 to BWL).
