What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests different ways of using digital tools to track diet, steps, and weight for weight loss in overweight or obese adults. People will use these methods to keep track of their eating and activity over several months. The goal is to find the best combination of tracking methods to help people lose weight effectively.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are currently using a weight loss medication or if weight loss might be impacted by a condition or medication.

Is digital self-monitoring for weight loss safe for humans?

The research does not specifically address safety concerns, but digital self-monitoring tools for weight loss, such as tracking diet and physical activity, are generally considered safe for human use. ^{1 2 3 4 5}

How is the Core behavioral weight loss intervention treatment different from other weight loss treatments?

The Core behavioral weight loss intervention is unique because it uses digital health strategies to support long-term weight loss by combining persuasive system design principles and behavior change techniques. This approach allows for personalized, scalable, and cost-effective interventions that can be delivered widely through digital platforms, unlike traditional in-person methods. ^{2 6 7 8 9}

What data supports the effectiveness of this treatment for weight loss?

Research shows that digital tools for self-monitoring diet, steps, and weight can help people lose weight by encouraging behavior change. Studies found that the more people engage with these digital programs, like logging meals or reading articles, the more weight they tend to lose. ^{1 2 6 7 10}

Published Research Related to This Trial

In a study of 11,252 participants using the Noom mobile app, higher engagement in activities like logging meals and reading articles was significantly associated with achieving moderate (5-10% weight loss) and high (10% or greater weight loss) outcomes compared to stable weight.

The relationship between engagement and weight loss outcomes was consistent over time, indicating that sustained participation in the program is crucial for long-term weight management success.

The study developed a digital behavior change intervention called eCHANGE, which integrates persuasive system design (PSD) principles and behavior change techniques (BCTs) to support long-term weight maintenance, based on input from 45 stakeholders including end users and health care providers.

Seventeen key design features were identified and grouped into four main components of the intervention, emphasizing personalization, self-monitoring, and social support, which are crucial for engaging users and promoting sustainable behavior change.

The study involved 809 Brazilian adults with overweight and obesity, using the Behaviour Change Wheel (BCW) framework to develop a web platform aimed at promoting weight loss through targeted behavior changes over a 24-week intervention.

The platform's functionalities were categorized based on the BCW components, showing that motivation-driven features were accessed the most, indicating their potential effectiveness in engaging users, while capability-driven features had lower usage, suggesting areas for improvement in behavior diagnosis and implementation.

In a 6-month trial involving 153 adults with overweight and obesity, a personalized digital weight loss program (WeightWatchers) led to an average weight loss of 5.05% from baseline, with 51% of participants achieving at least a 5% weight loss, indicating its efficacy.

Participants reported high satisfaction and engagement with the program, with significant improvements in various health-related behaviors, including increased fruit and vegetable intake, physical activity, and better sleep quality, suggesting the program's positive impact on overall well-being.

The study will involve adults aged 18 to 70 with overweight or obesity, using digital tools for self-monitoring in a 24-month behavioral weight loss program aimed at achieving and maintaining a 10% weight loss.

It will explore the effectiveness of different data sharing partnerships (with coaches, group members, and friends/family) on long-term weight loss, potentially revealing how these interactions can enhance weight loss outcomes.

This pilot trial involves 80 overweight or obese rural men aged 40-69 and aims to assess the feasibility and acceptability of two mobile applications for weight loss over a 6-month period.

The study will compare a more comprehensive intervention (MT+) that includes a self-monitoring app, discussion group, text support, and Wi-Fi scale against a basic app (MT), to evaluate their effectiveness in promoting weight loss and improving dietary and physical activity behaviors.

The NoHoW project developed a digital toolkit aimed at promoting long-term weight management, tested in an 18-month randomized controlled trial involving adults who had lost at least 5% of their body weight in the previous year.

The toolkit included 34 sessions across 15 modules, utilizing web-based tools and digital tracking devices to target weight, physical activity, and dietary behaviors, demonstrating a systematic approach to behavior change that could enhance weight loss maintenance strategies.

The SMART intervention, which utilized social and mobile technologies for weight loss, showed significant short-term weight loss at 6 and 12 months among young adults, but did not maintain this effect at 24 months, indicating limited long-term efficacy.

While the intervention was generally safe, there was one serious adverse event (gallstones) linked to rapid weight loss, highlighting the need for careful monitoring in weight loss programs.
