Continuous data are presented as means ± SDs, and categorical data are presented as percentages. Changes in adiposity parameters over 2 y are compared with the initial 6-mo change. *Different from baseline values, P < 0.05. POUNDS Lost, Preventing Overweight Using Novel Dietary Strategies.
From the 367 participants with dietary data at baseline, 356 had data at 6 mo. Only 186 had data at 2 y, and thus variety scores at 2 y were not computed.
Habitual physical activity was assessed by use of the validated 16-item Baecke physical activity questionnaire (21), and total physical activity was calculated by summing the leisure, sports, and work activity indexes.
Changes in adiposity parameters are computed as the differences from baseline.
Percentages of body fat and trunk fat were measured by use of DXA.
