Summary
Maintaining weight loss is challenging. A new shifting processes model, based on biopsychosocial and family systems theories, better explains the transition from weight loss to long-term weight-loss maintenance.
Area of Science:
- Behavioral Science
- Psychology
- Health Psychology
Background:
- Weight-loss maintenance is a significant challenge.
- The transtheoretical model (TTM) describes stages of change, including action (weight loss) and maintenance.
- However, TTM inadequately explains the transition between these stages.
Purpose of the Study:
- To propose a novel shifting processes model.
- To describe the complexities in shifting from weight loss to weight-loss maintenance.
- To integrate biopsychosocial and family systems theories.
Main Methods:
- The study proposes a new theoretical model.
- It draws upon Engel's biopsychosocial model and family systems theory.
- It focuses on relational contexts influencing the shift.
Main Results:
- The proposed shifting processes model offers a more nuanced understanding.
- It highlights potential differences between weight loss and maintenance processes.
- Relational contexts are identified as crucial factors.
Conclusions:
- The shifting processes model provides a richer framework for understanding weight-loss maintenance.
- It emphasizes the importance of relational factors in sustaining weight loss.
- This model offers new insights beyond the transtheoretical model.

01:25Models of Health Promotion and Illness Prevention I
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Adopting a healthier lifestyle often requires overcoming significant challenges, but leveraging psychological, social, and cultural resources can facilitate meaningful change. Effective self-change hinges on understanding and applying key tools such as motivation and goal setting, which help sustain efforts toward long-term health benefits.

01:29Concepts of Health and Illness
Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...
01:18Models of Health Promotion and Illness Prevention II
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

01:09Clearance Models: Physiological Models
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's proficiency in drug...

01:15Model Approaches for Pharmacokinetic Data: Physiological Models
Physiological models in pharmacokinetics are instrumental in understanding the distribution and elimination of drugs within the body. These models describe the drug concentration within target organs, influenced by factors such as drug uptake, tissue volume, and blood flow. Drug uptake is governed by the partition coefficient, which signifies the drug concentration ratio in tissue to that in the blood. The blood flow rate to a specific tissue is expressed as Qt, and the rate of change in tissue...
