ĭigital technologies have been incorporated into obesity prevention and weight loss strategies as they have become integrated into everyday life for many individuals. Weight cycling may put additional stress on the cardiovascular system through negative effects on blood pressure levels, heart rate, sympathetic activity, glucose, lipids, and insulin. However, frequently people who lose weight from lifestyle interventions like DPP regain weight after 12 months, which can have adverse health consequences and be more costly due to repeatedly returning to weight loss programs. Large behavior change trials such as the Diabetes Prevention Program (DPP) have shown that changes in lifestyle can have dramatic effects on health and chronic disease, often related to weight reduction. Ĭhanges in lifestyle behaviors such as diet and physical activity are frequently used in weight loss interventions. Among people with obesity, losing weight and maintaining a healthy weight can prevent future comorbidities and health complications. While prevention of obesity and weight gain is crucial to reducing the incidence of serious chronic illnesses, efforts to reverse obesity are just as urgent as the prevalence of obesity increases. Obesity is a growing public health and economic burden as it is a leading cause of chronic illnesses and mortality, resulting in extraordinary healthcare costs. This study characterized and demonstrated the utility of Foodsmart, a digital platform that gives personalized nutrition recommendations and meal planning tools, in sustained weight reduction among users with obesity. In total, 39.3 % (684/1,740) of participants lost at least 5 % of their initial weight, and 22.4 % percent (389/1,740) of participants sustained weight loss. Over a median of 25 months, the mean (standard deviation) change in weight among participants was − 6.2 (19.8) pounds. We used multivariate logistic regression models to examine the association between user characteristics and odds of sustained weight loss. A healthy eating score, Nutriscore, was calculated to assess overall diet quality. We defined sustained weight loss as participants who lost 5 % of initial weight between their first and second reported weights and lost weight or maintained weight between second and third reported weights. Participants reported age, gender, at least three measures of weight, and their diet using a food frequency questionnaire. We conducted a retrospective analysis of 1,740 adults with obesity who used Foodsmart, a digital personalized dietary assessment, meal planning and food purchasing platform. However, while many traditional dieting, food tracking and weight loss coaching programs result in short-term weight loss, there is less evidence of their effectiveness on sustaining weight loss over time. Previous studies have shown that lifestyle changes, such as diet and exercise, can lead to weight loss, resulting in dramatic improvements in overall health and chronic disease risk.
