Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Stress Prevention and Stress Management Techniques VI

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.
Motivation and Self-Determination
Motivation, the driving force behind behavior, plays a pivotal role at every stage of the change process. The research...

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Background:

Weight loss maintenance is challenging despite short-term program success.
Digital technologies offer scalable, low-cost behavior change interventions.
The Navigating to a Healthy Weight (NoHoW) project aimed to create a digital toolkit for sustained weight management.

Purpose of the Study:

Describe the development of the NoHoW Toolkit, including logic models, content, and specifications.
Report on user testing results for the NoHoW Toolkit.
Evaluate the toolkit's potential for long-term weight management.

Main Methods:

Systematic development using theory-based logic models and behavior change techniques.
Translation into a web-based app (NoHoW Toolkit) with technical development.
User evaluation and refinement of the toolkit through a large-scale international randomized controlled trial.

Main Results:

The toolkit features web-based tools and digital tracking device integration (smart scales, activity trackers).
It includes 34 sessions across 15 modules over 4 months, covering weight, physical activity, and dietary behaviors.
Interventions focused on motivation, self-regulation, and emotion regulation, with data monitoring for weight, steps, diet, mood, and sleep.

Conclusions:

A systematic, theory- and evidence-based approach with user testing enhances digital behavior change solutions.
The NoHoW Toolkit development provides a model for improving sustained weight management interventions.
The 2x2 factorial trial design uniquely examined the separate and interactive effects of motivation, self-regulation, and emotion regulation on weight loss maintenance.
