Twenty-five-year-old Maggie needed to lose 1,000 pounds, but the staff members of the Alaska Zoo in Anchorage didn’t know what to do with her robust 9,000-pound body. Maggie had matured into a particularly pudgy pachyderm and was dangerously obese. Following the Heart Zones way, the zoologist devised a new high-fiber, high-fruit diet and then made her work hard for her food, by putting it in high baskets so that she would have to forage for it. Her personal trainer, Beth, and her team next ordered a special treadmill that was 20 feet long and 5 feet wide. The goal is to get Maggie walking on the treadmill three times a day for 30 minutes each session. Maggie is now down to 7,500-8,000 pounds, with this combination of aerobic exercise, emotional stimulation, and a new dietary regimen. If it works for a pachyderm, it should work for most others facing the serious consequences of obesity.
