Measurements. At screening, body weight was measured to the nearest 0.1 kg and height to the nearest 0.1 cm using a calibrated scale (Tanita BWB-800A Class III scale, Tanita) and a stadiometer (Detecto Industrial Scales of New York), respectively. Blood pressure measurements were obtained weekly with the participant in a seated position after a 2- to 3min resting period. Two separate blood pressure measurements were taken and averaged.Both body weight and blood pressure measurements were taken at each weekly visit to the WeightControlUnit. Waist and hip circumferences were obtained at baseline, wk 6, and wk 12 of each study period. Waist circumference was measured at the level of the umbilicus (13) and hip circumference was measured at the point of maximum girth over the buttocks while participants stood with their heels placed together.
