Table 1.

Anthropometric and energy expenditure variables in 14 of the original 16 study subjects who participated in the 30 week Biggest Loser weight loss competition. The predicted RMR was obtained using a linear regression equation developed using baseline data on body composition, age, and sex in the full 16 subject cohort. The p values were not adjusted for multiple comparisons.
