By his junior year at North Central High School, Fogle's weight was at 425 pounds (193 kg), and he reportedly wore size 6XL shirts[1].
Several years later, after his roommate, a pre-med student, correctly diagnosed Jared with sleep apnea and edema, he was sent to the hospital. Fogle's father, who is a physician, told him he might not live past 35, and Jared began to turn his life around. At the age of 20, Fogle estimated he consumed a diet of around 10,000 calories a day.[2]
Interested by Subway's "7 Under 6" campaign, Fogle went and tried his first turkey club, and enjoyed the sandwich.[1] He developed his own "Subway diet", consisting of a 6-inch turkey club sandwich for lunch, and a foot for dinner.[1]
After three months on the diet, he had lost nearly 100 pounds, and weighed in at 330 pounds (150 kg). He stuck with the diet and soon began to walk as much as he could, rather than using transport, and would even walk up the stairs rather than take an elevator. By the end of the diet Jared lost over 240 pounds (109 kg)[1]
