Timeline
Healthy, weight-stable adults
Healthy, weight-stable adults (18–65 years of age; body mass index [BMI], 25–40 kg/m2) who owned smartphones were recruited from a campus community to participate in an 8-week weight loss trial. Participants (n = 57) were free of unresolved medical conditions and did not take medications or supplements known to affect body weight. All participants reported no dieting or weight changes of greater than ± 5 lb in the past 3 months and agreed to record all food intake during the trial using their smartphone or a paper-based diet log.
