Introduction Overweight and obesity are risk factors for noncommunicable diseases, such as type 2 diabetes, cardiovascular disease, and some cancers.14 Globally, the prevalence of obesity and overweight has significantly risen over the past three decades,5 and the projected obesity trends are expected to enhance its economic burden.6 In Taiwan, the prevalence of obesity in adults has also increased over the past two decades, and approximately half of adults in Taiwan have become overweight or obese.7,8 Weight loss through lifestyle modification can significantly produce health benefits.912 However, only a small proportion of patients with obesity undergoing lifestyle modification achieve clinically significant weight loss and weight loss maintenance.13,14 To date, no country has succeeded in reversing the current obesity pandemic.15 Since coronavirus disease 2019 (COVID-19) was declared a global pandemic,16 several studies conducted in different countries have shown lower diet quality, higher overeating frequency, less physical activity, and weight gain during the COVID-19 pandemic compared to before the COVID-19 pandemic.1720 Furthermore, obesity increases the risk of severe COVID-19 illness, hospitalization, and mortality.2124 However, weight management programs for obesity have been reduced during the COVID-19 pandemic to ensure the safety of patients and healthcare professionals.25 Thus, remote approaches instead of face-to-face interactions for weight management are required. Prior to the COVID-19 pandemic, many studies demonstrated that telehealth and mobile health (mHealth) technologies are effective tools for weight loss treatment.26 Weight loss treatment delivered by smartphone applications (apps) may lead to higher adherence and greater weight loss compared to that delivered by websites or paper diaries.27 In the Asian population, the use of a mobile app applied to weight loss may also have benefits for improving diet quality and weight loss self-efficacy.28,29 During the COVID-19 pandemic, the use of telehealth increased by almost 200% in the US.30 Recently, a randomized clinical trial, using the mHealth app to promote ketogenic diet during the COVID-19 pandemic, found that self-reported dietary adherence is an important predictor of weight-loss success.31 Thus, telehealth technologies may be a feasible choice for weight management during the COVID-19 pandemic. Although a nation-wide lockdown was not implemented until May 18, 2021, a social distancing policy was implemented after a locally-transmitted COVID-19 infection was reported on January 21, 2020 in Taiwan.32 Assembly and gathering were restricted according to public assembly guidelines published by the Taiwan Centers for Disease Control
