What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how effectively an Integrated Lifestyle Intervention (a structured lifestyle program) can manage weight when combined with physical activity support. It tests various combinations, including group classes, one-on-one sessions, fitness app memberships, and mental imagery exercises. The target participants are individuals with a BMI between 25 and 45 who have engaged in less than 150 minutes of moderate exercise weekly for the past three months. This trial is designed for those interested in a structured weight management plan without enrolling in other programs. As an unphased trial, it offers a unique opportunity to participate in innovative weight management strategies.

Will I have to stop taking my current medications?

The trial requires that participants do not regularly use medications that significantly impact appetite, weight, sleep, or energy metabolism, such as appetite suppressants, lithium, stimulants, anti-psychotics, and tricyclic antidepressants. If you are taking any of these, you may need to stop before joining the study.

What prior data suggests that this integrated lifestyle intervention is safe?

Research has shown that lifestyle changes, like those in this study, are generally safe. Studies have found that programs involving diet changes, exercise, and support can help people lose weight and improve health. Most participants find them easy to follow without issues.

These programs often lead to moderate weight loss and a decrease in body mass index (BMI), indicating effectiveness without harm. Overall, participants in similar programs have not reported serious side effects, making these lifestyle changes a safe option for managing obesity. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Integrated Lifestyle Intervention for Obesity because it combines several innovative approaches to weight management. Unlike standard treatments that often focus solely on diet or exercise, this intervention integrates a structured lifestyle program with group classes led by a registered dietitian, personalized one-on-one support, and mental imagery techniques to enhance motivation and engagement. Additionally, some treatment arms include access to the Peloton fitness app, which offers a flexible and engaging way to stay active. This comprehensive strategy not only addresses physical health but also the psychological aspects of weight management, potentially leading to more sustainable results.

What evidence suggests that this trial's treatments could be effective for obesity?

Research has shown that combining diet, exercise, and behavior changes can lead to significant weight loss. In this trial, participants will join different treatment arms, each incorporating elements such as group classes, personal coaching, fitness memberships, and mental imagery. For example, some studies have found that people can lose about 4.19 kilograms on average, and 40.3% may lose at least 5% of their body weight. These programs often include support like group classes and personal coaching, which help individuals make and maintain healthy changes over time. Additionally, more than half of the participants in certain studies achieved weight loss that significantly improved their health. Overall, these combined lifestyle approaches effectively reduce obesity. ^{1 3 4 6 7}

Trial Overview

The study is testing the integration of the Move physical activity support program into an existing lifestyle intervention. Participants will receive various supports such as one-on-one coaching, mental imagery techniques, fitness memberships, group-based classes, and Prevent T2 strategies to encourage healthier living habits.

How Is the Trial Designed?

Group I: PreventT2 + Move group-based classes + Move 1:1 Support Experimental Treatment 3 Interventions

Participants will receive a 6-month lifestyle weight management program based on the publicly available Prevent T2 curriculum (formally known as the National Diabetes Prevention Program), integrated with the Move group-based classes.

Published Research Related to This Trial

A lifestyle intervention program combining diet, exercise, and psychological support significantly improved lifestyle-related behaviors in 60 overweight and obese patients over 6 months, as evidenced by better scores in dietary caloric intake, physical activity, and healthy eating.

The program also led to positive changes in body composition parameters, indicating that such comprehensive interventions can effectively support weight management in a primary healthcare setting.

[Effectiveness of a program for treatment of overweight and nonmorbid obesity in primary healthcare and its influence lifestyle modification]. Arrebola Vivas, E., Gómez-Candela, C., Fernández Fernández, C., et al.[2015]

Comprehensive lifestyle modification programs delivered in person can lead to an average weight loss of about 10% over 16-26 weeks, while web-based interventions typically result in around 5% weight loss, highlighting the effectiveness of in-person support.

Combining lifestyle changes with long-term medication use may enhance initial weight loss and help maintain weight loss over time, suggesting a multi-faceted approach could be beneficial for obesity management.

A 12-month study involving 147 obese patients with type 2 diabetes showed that a lifestyle intervention program led by dietitians resulted in significantly greater weight loss (3.0 kg) and reduced waist circumference (-4.2 cm) compared to usual care.

Participants in the lifestyle case management group also experienced improved HbA1c levels, reduced use of diabetes medications by 0.8 medications per day, and enhanced health-related quality of life across multiple domains, indicating the program's effectiveness in managing diabetes and obesity.

A comprehensive lifestyle modification program can lead to a significant weight loss of about 10% of initial body weight within 16 to 26 weeks, especially when delivered through group or individual on-site treatments.

Long-term weight control is enhanced by ongoing contact with healthcare providers, high physical activity levels, and the use of medications alongside lifestyle changes, which also help in reducing cardiovascular risk factors.

Lifestyle modification therapy can lead to a significant weight loss of 8-10% over approximately 30 weeks for overweight and obese patients, combining diet, exercise, and behavioral strategies.

To enhance the effectiveness and sustainability of this therapy, new strategies such as individualized treatment, remote delivery via phone or internet, and integration with community programs or bariatric surgery have shown promising results.
