JT—Spiraling Out of Control?

JT, a retired computer company executive, eats out four times a week since his wife died last year. Meals at home consist of microwave dinners or supreme pizza. He belongs to a health club, which he visits three times a week, and where he has many friends. Occasionally, JT and his friends go out for beers after their workout. Shortly after his 69th birthday (2 years ago), he was diagnosed with type 2 diabetes. Last week, he visited the clinic for his annual checkup. He was measured at 5 feet 9 inches (1.75 m) and weighed 235 pounds (106.8 kg). His doctor is worried about JT’s family history of heart disease.
