Study Arms:
- Exercise Training (Type: ACTIVE_COMPARATOR): Exercise participants will undergo a 1-hour supervised exercise program 3 times per week for 20 weeks consisting primarily of walking exercise using an individualized exercise prescription based on the initial exercise stress testing results.
- Dietary Intervention (Type: ACTIVE_COMPARATOR): A hypocaloric diet will be developed to achieve a 2800 kcal/week deficit, which should produce about 0.4 kg (1 lb) weight loss per week.
- Attention control (Type: ACTIVE_COMPARATOR): Attention control participants will be provided a counseling session regarding general health education at baseline and will be contacted by staff via telephone every 2 weeks to discuss general health status.
- Diet and Exercise (Type: ACTIVE_COMPARATOR): A hypocaloric diet will be developed to achieve a 2450 kcal/week deficit in addition to undergoing a 1-hour supervised exercise program 3 times per week for 20 weeks consisting primarily of walking exercise using an individualized exercise prescription based on the initial exercise stress testing results.

Based on this trial design, predict the completion outcome and termination type (if applicable).
