What side effects are associated with this type of intervention?

Common weight loss treatments, including reduced-calorie diets and increased physical activity, can lead to side effects such as fatigue, irritability, nutritional deficiencies, muscle soreness, joint pain, and risk of injury. Technology-based interventions like JITAI, which provide real-time support, are generally safe but may cause over-reliance on devices, data privacy concerns, and potential anxiety from constant monitoring.

What prior FDA approvals exist?

The FDA has approved several drugs for weight loss, including orlistat, which reduces fat absorption, and sibutramine, which was withdrawn due to cardiovascular risks. More recent approvals include liraglutide and semaglutide, which are GLP-1 receptor agonists that help regulate appetite and caloric intake. These medications, combined with lifestyle modifications, align with the principles of Just-in-Time Adaptive Interventions (JITAI) by providing support to manage dietary and physical activity behaviors.

What other types of research exist?

Promising, novel alternatives to Just-in-Time Adaptive Intervention (JITAI) for weight loss patients in 2024 include: 1) Digital self-help interventions that provide structured guidance and support through internet-based platforms. 2) Smartphone applications that facilitate self-monitoring and offer real-time feedback and motivation. 3) Integrated therapy approaches that combine cognitive-behavioral therapy (CBT) with nutritional counseling and physical activity guidance. These methods leverage technology and evidence-based practices to offer personalized and effective support for weight loss.

Summary

This trial will study how individuals' everyday lives impact their ability to stick to a healthier diet & more physical activity to help them lose weight.

Who is the study for?

This trial is for adults aged 18-65 in the U.S. with a BMI of 27-50, who own a smartphone with data and can understand English. It's not for those in other weight loss programs, pregnant or planning to be, recently changed weight-related meds, have certain medical/psychiatric risks or eating disorders.Check my eligibility

What is being tested?

The study tests how technology like smartphones and Fitbit can track real-time risk factors that lead to lapses during weight loss efforts. The goal is to develop personalized interventions that provide immediate support to prevent these lapses.See study design

What are the potential side effects?

Since this trial involves behavioral changes rather than medication, traditional side effects are not expected. However, participants may experience stress or frustration related to adherence to diet/activity plans and frequent monitoring.

Other Research

Common weight loss treatments, particularly those similar to Just-in-Time Adaptive Interventions (JITAIs), work by providing personalized, real-time support to address momentary risk factors like cravings or emotional triggers. These interventions use technology such as smartphone apps and sensors to deliver tailored guidance and feedback in the moment, helping individuals stick to their diet and exercise plans. This real-time support is crucial for weight loss patients as it helps prevent lapses in adherence, thereby enhancing the effectiveness of behavioral strategies and increasing the chances of achieving and maintaining weight loss.
