Open-ended feedback underscored the value of the group-based structure of the program and remote delivery to reduce travel burden, the need for reduced burden associated with food logging, and the need to identify methods for enhancing perceived value of TRE among older adults. An intervention designed to promote CR, primarily delivered remotely and supported by self-monitoring technologies, is both feasible and acceptable to many older adults.  \nAbstract citation ID: igaf122.1018  \nINTERVENING ON CALORIE INTAKE OR EATING  \nTIMING IN OLDER ADULTS: LESSONS LEARNED IN  \nTHE HALLO-P TRIAL  \nJason Fanning1, Stephen Kritchevsky2, Michael Miller2, Denise Houston2, Michael Walkup2, Cynthia Stowe2,  \nW.

Community-dwelling older adults with obesity or overweight with an indication for weight loss were randomized to 9 months of group-based CR, RCR, or TRE supported by self-monitoring technologies [i.e., a tablet application, activity monitor (all), wireless scale (CR and RCR)] . Intervention staff recorded attendance at sessions and noted intervention-related lessons learned as they arose, and participants provided feedback related to their experiences in the trial. Participants (N = 90; 67.19±4.91 years) attended 84.4% of sessions on average, engaged with study technologies 96.4% of days, and provided daily weights on > 4 days per week across the study (CR and RCR only).
