MET: metabolic equivalent; LPA: light-intensity physical activity (1.5 to <3.0 METs); MVPA: moderate-to-vigorous physical activity (≥3.0 METs).

^*Controlling for intervention group and baseline age, sex, race, ethnicity, education, employment, household income, student status, marital status, children, body mass index, percentage time sedentary, LPA MET-min/week, MVPA MET-min/week in ≥10 minute sessions, caloric intake, % calories from protein and % calories from fat.

^**Negative value indicates higher percent of weight loss.
