Health Achieved Through Lifestyle Transformation (HALT): A Kaiser Permanente Diet and Lifestyle Intervention Program for Coronary Artery Disease and Type 2 Diabetes.

A whole-food plant-based (WFPB) diet in combination with healthful lifestyle modifications has been shown to be an effective approach to managing and reversing the progression of coronary artery disease and type 2 diabetes mellitus (T2DM). The Health Achieved Through Lifestyle Transformation Program (HALT) is a 20-week real-world healthful diet and lifestyle intervention program implemented at Kaiser Permanente South Sacramento Medical Center (KPSSC), whose goal is to treat, and where possible, reverse CAD and T2DM. Here, our objective is to describe HALT, including enrollment, the intervention, adherence, and data collection activities during a 2-year period from October 15th, 2016, through October 9th, 2018. There were 204 KPSSC members enrolled, of which, 19 (9.3%) had CAD only, 166 (81.4%) had T2DM only, and 19 (9.3%) had both CAD and T2DM. Among the enrolled, 196 (96.1%) completed self-administered questionnaires, and 88.2 to 97.5% completed blood tests, depending on the test. The enrolled were predominantly female (63.2%), ≥50 years old at program entry (83.3%), and white (32.8%) or black (25.5%). HALT has the potential to become a valuable resource for examining the impact of dietary and lifestyle modifications on patients diagnosed with CAD and/or T2DM.
