Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Rehab Only
Patients will be randomized to Rehab only using a randomization scheme with blocking stratified by sex and obesity severity (BMI\<30 vs. BMI≥30 kg/m2). All participants will undergo standard exercise-based cardiac rehabilitation, which includes meeting with dietitian, exercise, health education, and exercise compliance.
Exercise
Each exercise session lasts for 60 to 90 minutes and consists of 5-10 minutes of warm-up and cool-down activity; up to 30 minutes of aerobic exercise using a variety of modalities (e.g., walking laps on a track, cycle ergometry, treadmills, stair climbers); and 15-20 minutes of upper and lower body resistance exercises using Thera-Bands. An exercise physiologist creates an individualized plan
Health Education
Group education classes conducted by an exercise physiologist and/or dietitian are designed to provide support and general information on healthy lifestyle behaviors. Topics include risk factor control, diabetes, hypertension, lipids, medications, aerobic exercise, strength training and flexibility, weight control, reading food nutrition labels, eating out, holiday eating, intimacy, stress, relaxation, cardiac symptoms, and cardiac interventions.
Exercise Compliance
Multiple behavioral management strategies to create a positive exercise environment and promote adherence and retention will be utilized. These include promptly contacting participants who miss a session, scheduling makeup sessions, and offering individual counseling sessions to discuss strategies to promote attendance and limit obstacles to participation.
Dietary Counseling
Participants have one meeting with the Rehab dietitian upon starting.
Rehab+Weight Loss (WL)
Patients will be randomized to Rehab+WL using a randomization scheme with blocking stratified by sex and obesity severity (BMI\<30 vs. BMI≥30 kg/m2). All participants will undergo standard exercise-based cardiac rehabilitation in addition to a weight-loss intervention, which includes meeting with dietitian, exercise, health education, and exercise compliance, calorie-restricted diet, behavioral modification, and weight-loss compliance.
Exercise
Each exercise session lasts for 60 to 90 minutes and consists of 5-10 minutes of warm-up and cool-down activity; up to 30 minutes of aerobic exercise using a variety of modalities (e.g., walking laps on a track, cycle ergometry, treadmills, stair climbers); and 15-20 minutes of upper and lower body resistance exercises using Thera-Bands. An exercise physiologist creates an individualized plan

Topics include risk factor control, diabetes, hypertension, lipids, medications, aerobic exercise, strength training and flexibility, weight control, reading food nutrition labels, eating out, holiday eating, intimacy, stress, relaxation, cardiac symptoms, and cardiac interventions.
Exercise Compliance
Multiple behavioral management strategies to create a positive exercise environment and promote adherence and retention will be utilized. These include promptly contacting participants who miss a session, scheduling makeup sessions, and offering individual counseling sessions to discuss strategies to promote attendance and limit obstacles to participation.
Calorie-Restricted Diet
Diet plans will provide a caloric deficit of 500 kcals per day. The lowest calorie level permitted will be 1,100 kcals for women and 1,200 kcals for men. The calorie distribution goal will be 15-20% from protein, \<30% from fat, and 45-60% from carbohydrates. Participants will consume 2 meal replacements per day (Premier Protein shakes and bars); provided by the study)), along with one meal composed of traditional foods (500-750 kcals, low in fat, high in vegetables), and 1-3 snacks as needed (e.g., cereal bar, fruit, or vegetable, providing 100-150 kcals each). For the meal, patients will follow a weekly menu plan and recipes provided by the study. The food plan will be tailored to individual preferences and energy needs.
Behavioral Modification
During months 1-3, participants will attend weekly individual behavioral counseling sessions with the study registered dietitian (RD); individual sessions will be held twice per month during months 4-6. The sessions will focus on self-monitoring, portion control, mindful eating, coping with negative thoughts, eating at regular times, and stress management. The RD will review individual progress, solve problems, answer questions, and set weight loss goals.
Weight-Loss Compliance
Participants will be asked to record their food and beverage intake in daily logs which will be reviewed weekly by the RD to verify compliance to the diet. Body weight will be measured weekly to ensure that participants are losing weight at an appropriate rate. If a participant is not meeting weight loss goals, energy intake will be modified accordingly to produce the desired rate of weight loss.
