Prologue
Falling Off the Diet Wagon 
When Kirstie Alley stepped on the scale for the fi rst time in 
15 months, she had a hunch that it wouldn’t be pretty. “I thought 
I weighed 190, but I got on the scale and started screaming,” 
recalls Alley. “It said 228 lbs., which is my highest weight ever.” 
But looking back, Alley, 58, is hardly shocked that her body. . . 
had ballooned beyond 200 lbs. yet again. . . . She had not worked 
out and even banished her gym equipment to the garage. As for 
her diet, her small, low-calorie portions gave way to Chinese 
takeout and pasta drenched in butter. 
“I fell off the horse,” says the 5’ 8” star. . . I just sort of went wild.” 
(Leonard, 2009, p. 50)
