Abstract:
It remains largely unknown as to why some individuals experience substantial weight loss with obesity interventions, while others receiving these same interventions do not. Person-specific characteristics likely play a significant role in this heterogeneity in treatment response. The practice of precision medicine accounts for an individual's genes, environment, and lifestyle when deciding upon treatment type and intensity in order to optimize benefit and minimize risk. In this review, we first discuss biopsychosocial determinants of obesity, as understanding the complexity of this disease is necessary for appreciating how difficult it is to develop individualized treatment plans. Next, we present literature on person-specific characteristics associated with, and predictive of, weight loss response to various obesity treatments including lifestyle modification, pharmacotherapy, metabolic and bariatric surgery, and medical devices. Finally, we discuss important gaps in our understanding of the causes of obesity in relation to the suboptimal treatment outcomes in certain patients, and offer solutions that may lead to the development of more effective and targeted obesity therapies.
Insights
Individual characteristics significantly impact obesity treatment success, leading to varied weight loss outcomes. Precision medicine aims to tailor therapies for better results by considering personal factors.
Area of Science:
- Obesity research
- Precision medicine
- Personalized treatment strategies
Background:
- Obesity is a complex disease with diverse biopsychosocial determinants.
- Significant heterogeneity exists in individual responses to obesity interventions.
- Understanding person-specific factors is crucial for effective obesity management.
Purpose of the Study:
- To review the role of person-specific characteristics in obesity treatment response.
- To explore the application of precision medicine in obesity care.
- To identify gaps in understanding and propose solutions for targeted obesity therapies.
Main Methods:
- Literature review of biopsychosocial determinants of obesity.
- Analysis of studies on person-specific predictors of weight loss.
- Examination of evidence for various obesity interventions (lifestyle, pharmacotherapy, surgery, devices).
Main Results:
- Person-specific characteristics significantly influence weight loss outcomes across different obesity treatments.
- Genetics, environment, and lifestyle are key factors in treatment response variability.
- Current obesity interventions show suboptimal results in some individuals due to a lack of personalization.
Conclusions:
- Personalized approaches, guided by precision medicine principles, are essential for optimizing obesity treatment.
- Further research is needed to elucidate the complex interplay of factors driving obesity and treatment response.
- Developing targeted obesity therapies requires a deeper understanding of individual variability.
