Examination of whether early weight loss predicts 1-year weight loss among those enrolled in an Internet-based weight loss program.

ABSTRACT: One-month weight loss (WL) predicts posttreatment WL in face-to-face interventions; however, whether this holds true within Internet programs is unknown. This study examined whether 4-week WL predicts WL following a 12-week Internet program and at 6 and 12 months follow-up. A total of 181 participants (body mass index=33.4±5.5 kg m(-)(2); 83.1% female) received a 12-week behavior-based Internet WL program consisting of weekly video lessons. Participants were given a daily WL, calorie and physical-activity goal and asked to enter these data on the study website weekly. Personalized feedback was provided. Using 4-week WL, individuals were categorized as 'early nonresponders' (<2.0% WL) or 'early responders' (⩾2.0% WL). Early nonresponders had significantly lower WL than early responders at 3
