In the 12-week intervention period, the intervention group received 8 text messages weekly based on the transtheoretical model of behavior change, 1 email weekly, 5 personalized coaching calls, a diet booklet, and access to resources and mobile phone apps on a website. Control group participants received only 4 text messages and printed dietary and physical activity guidelines. Measured body weight and height were collected at baseline and at 12 weeks. Outcomes were assessed via online surveys at baseline and at 12 weeks, including self-reported weight and dietary and physical activity measures. Results: A total of 214 participants---110 intervention and 104 control---completed the 12-week intervention period. A total of 10 participants out of 250 (4.0{\%})---10 intervention and 0 control---dropped out, and 26 participants (10.4{\%})---5 intervention and 21 control---did not complete postintervention online surveys. Adherence to coaching calls and delivery of text messages was over 90{\%}. At 12 weeks, the intervention group were 2.2 kg (95{\%} CI 0.8-3.6) lighter than controls (P=.005). Intervention participants consumed more vegetables (P=.009), fewer sugary soft drinks (P=.002), and fewer energy-dense takeout meals (P=.001) compared to controls. They also increased their total physical activity by 252.5 MET-minutes (95{\%} CI 1.2-503.8, P=.05) and total physical activity by 1.3 days (95{\%} CI 0.5-2.2, P=.003) compared to controls. Conclusions: The TXT2BFiT low-intensity intervention was successful in preventing weight gain with modest weight loss and improvement in lifestyle behaviors among overweight young adults. The short-term success of the 12-week intervention period shows potential. Maintenance of the behavior change will be monitored at 9 months.
