Active_comparator: Individual & Group Lifestyle Medicine-based Coaching

This group will receive personal and group coaching sessions based on the six pillars of lifestyle medicine: 1) a plant- predominant eating pattern (consistent with the AIH Full Plate Living program); 2) physical movement; 3) restorative sleep; 4) management of stress; 5) avoidance of risky substances; and 6) positive social connections. Target goals for the participants assigned to Lifestyle Coaching will include the following: improving diet quality together with moderate caloric restriction; engaging in more physical activity with a goal of 150 minutes or more per week of at least moderate intensity (e.g. brisk walking); getting 7-8 hours of sleep nightly when possible and using short naps when work or other conditions interfere with getting at least 7 hours of sleep; increasing resilience and using positive social/family connections to manage/decrease stress.
