COVID-19-related motivation to lose weight on a digital weight loss program

ABSTRACT

Background: Obesity is considered a risk factor for severe COVID-19 illness. Thus, individuals with obesity may be especially motivated to lose weight because of COVID-19. To our knowledge, this is the first study to assess COVID-related motivators to lose weight and whether they predict weight loss. Methods: In this prospective study, 530 new users of a digital commercial weight loss program completed a baseline survey in January 2021 assessing overall motivation to lose weight due to COVID (one item 'how much of your interest in losing weight is because of COVID-19 or its impact, however minor, on your life?'), and three specific COVID motivators. These specific motivators were measured by the validated Fear of COVID-19 scale (F-C), one item assessing motivation to improve eating habits which got worse during COVID-19 (EH-C), and one item assessing motivation to prevent diseases that could increase COVID-19 risk (D-C). The main outcome was weight loss at 2 months, extracted from self-reported weight on the program. Results: Participants were 84% female, had a median age of 46, mean baseline BMI of 32.12 (SD = 6.96), and lost 3.13kg (3.49%) at 2 months (SD = 2.72kg). Overall COVID motivation was high;66% reported that their interest in losing weight was due to COVID. There was high F-C (M = 25.2 out of 35) and EH-C (M = 7.7 out of 10), and moderate D-C (M = 5.4 out of 10). Despite high COVID-related motivation, overall motivation, F-C, and EH-C did not predict weight loss at 2 months. D-C marginally significantly predicted weight loss at 2 months (B = -. 09, p = .06). Conclusions: Results suggest that even though individuals showed initial high motivation due to COVID, it did not manifest in actual weight loss, except in the most at-risk individuals who sought to prevent diseases that put them at greater risk. Individuals may need support to translate initial COVID-related motivation to actual weight loss. Next, we will examine relationships between COVID motivators, vaccination status, and weight loss at 4 months.
