Study summary

This study was designed to test the impact of a 12-week online behavioral modification program for weight loss, with or without a fortified beverage. Subjects are randomized to four conditions: 1) Online Basic Lifestyle Counseling (OBLI); 2) Online Lifestyle Counseling (OLC); 3) OBLI plus a beverage (BEV); 4) OLC + BEV. The three hypotheses were: 1)after 12 weeks, individuals in the OLC condition would lose more weight than those in OBLI; 2) after 12 weeks, the OLC + BEV condition would lose more weight than the OLC condition; and 3) after 12 weeks, the OBLI + BEV condition would lose more weight than the OBLI condition.
