This week on Heart Doc VIP, Dr. Kahn revisits the powerful role exercise plays in overall health and its ability to extend your "healthspan"—the years you live free from chronic disease. He puts a unique spin on the topic by exploring two recent studies on the benefits of wearing weighted vests, both during workouts and throughout the day, for supporting weight loss maintenance.

Shorter topics this week include the link between excess weight and postmenopausal breast cancer risk, as well as the often absent warning signs before a first heart attack.
