What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand why people with lower income have more difficulty losing weight. Participants will follow a typical weight loss program, and researchers will study how focusing on immediate needs and daily stress affect their success. The goal is to find better ways to help these individuals stick to their weight loss plans.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are currently engaged in another weight loss therapy, you cannot participate.

Is behavioral weight loss treatment safe for humans?

Behavioral weight loss treatments, which include changes in diet, physical activity, and behavior, are generally considered safe for humans. They focus on helping people adopt healthier habits and have been used successfully to manage obesity without significant safety concerns. ^{1 2 3 4 5}

How is behavioral weight loss treatment different from other obesity treatments?

Behavioral weight loss treatment is unique because it focuses on changing eating, activity, and thinking habits through techniques like self-monitoring and cognitive restructuring, rather than relying solely on medication or surgery. It emphasizes long-term lifestyle changes and can be combined with other methods for better results. ^{1 6 7 8 9}

What data supports the effectiveness of the treatment for obesity?

Research shows that behavioral weight loss treatments can help people lose about 10% of their body weight, which can significantly improve health. These treatments often include changes in diet, exercise, and behavior, and have been successful in helping people maintain weight loss over time. ^{2 7 10 11 12}

Published Research Related to This Trial

Behavioral treatment can effectively lead to a 10% weight loss, which is significant enough to improve health outcomes for patients.

Maintaining weight loss is difficult, but long-term success can be enhanced by increasing patient-provider contact, encouraging physical activity, and combining lifestyle changes with medication.

Behavioral treatment of obesity. Butryn, ML., Webb, V., Wadden, TA.[2022]

Behavior modification for obesity treatment has evolved to systematically address various factors influencing eating and exercise, leading to an average weight loss of 9.9 kg over an 18-week treatment period.

Approximately 66% of the weight lost is maintained after one year, highlighting the need for longer-term strategies to prevent relapse in obesity, as it is a chronic condition.

NCBI (Pubmed)

Evidence for success of behavior modification in weight loss and control. Foreyt, JP., Goodrick, GK.[2019]

Short-term behavioral interventions for obesity typically result in an average weight loss of 10 kg during the program and 6.6 kg at one year follow-up, indicating some effectiveness in the short term.

To improve long-term weight management, a chronic disease model of obesity treatment is suggested, emphasizing the need for ongoing care and potentially incorporating highly structured diets and supervised exercise.

Behavioral treatment of severe obesity. Wing, RR.[2018]

A 29-year-old man successfully lost weight through a behavior therapy approach that included monitoring his eating and exercise habits, correcting misconceptions, and developing strategies for healthier living.

The weight loss achieved during treatment was significant and maintained at a 6-month follow-up, demonstrating the long-term efficacy of behavior therapy for obesity management.

Current treatment of obesity exemplified in a case study. Wyshogrod, D.[2019]

Weight loss of just 5-10% can significantly improve health issues related to obesity, such as hypertension and type II diabetes, as shown in studies like the Diabetes Prevention Program, which found a 7% weight reduction reduced diabetes risk by 58%.

Behavioral treatments, which include diet changes, increased physical activity, and behavior therapy, are effective in achieving and maintaining this level of weight loss, promoting long-term health benefits.

Lifestyle modification in the treatment of obesity: an educational challenge and opportunity. Jones, LR., Wilson, CI., Wadden, TA.[2007]

Behavioral treatment for obesity focuses on changing eating, activity, and thinking habits, acknowledging that weight is influenced by genetics, metabolism, and hormones.

This approach equips individuals with skills for managing weight, such as adopting a low-fat diet and increasing physical activity, although many may still be overweight after treatment.

An eight-week study involving 101 overweight participants showed that an internet-based behavioral therapy program (IBT) led to significantly greater weight loss (2.28 kg) compared to a standard email education program (0.74 kg).

Participants in the IBT group were also more successful in achieving a clinically significant weight loss of 5% of their initial body weight (17.6% vs. 2%), indicating that structured online interventions can be effective for obesity management.

Lifestyle modifications, including changes in diet and increased physical activity, are essential for treating obesity and reducing the risk of related cardiovascular diseases.

Behavior modification techniques, such as self-monitoring and cognitive restructuring, are effective strategies for changing obesity-related behaviors, and medication can also support these lifestyle changes in managing obesity.

Successful management of the obese patient. Poston, WS., Foreyt, JP.[2019]

Behavior therapy for obesity has evolved over the past 30 years, leading to increased average weight loss, but many individuals still struggle with regaining weight after treatment.

The study suggests that obesity should be viewed as a chronic health issue, and long-term behavior therapy programs may be crucial for helping some individuals maintain their weight loss over time.

Behavioral therapy for obesity. Williamson, DA., Perrin, LA.[2019]

Behavioral treatment for obesity can lead to an average weight loss of 8.5 kg (about 9% of initial weight) over approximately 20 weeks, highlighting its efficacy in helping individuals change unhealthy habits.

Combining behavioral strategies with weight-loss medications enhances the chances of successful weight maintenance, emphasizing the importance of a comprehensive approach to obesity treatment.

Behavioral treatment of obesity. Wadden, TA., Foster, GD.[2019]

Behavioral therapy is a key part of obesity treatment, focusing on self-monitoring and various techniques like stimulus control and cognitive restructuring, but most patients tend to regain weight over time, highlighting the need for long-term strategies.

To improve long-term success, behavioral therapy can be supplemented with other treatments like very-low-calorie diets or medications, and it's important to tailor approaches to individual needs, especially for subgroups like those with binge eating disorders.
