This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...

At its core, the cycle revolves around four distinct stages: need, drive, goal-directed behavior, and goal achievement. These stages respond to imbalances in the body or mind, prompting actions that restore balance.
The cycle begins with a need. This need can arise from various conditions, such as hunger, thirst, or temperature changes. For instance, when an individual feels cold, their body...

Models 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.

It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

Area of Science:

Behavioral Science
Health Psychology
Digital Health Interventions

Background:

Maintaining motivation is crucial for successful weight loss.
Online interventions offer scalable solutions for weight management.
Motivational interviewing (MI) is a counseling approach to enhance intrinsic motivation.

Purpose of the Study:

To assess the feasibility and acceptability of MI in online weight-loss groups.
To explore the impact of MI on participant motivation and weight loss outcomes.

Main Methods:

Pilot study with 20 women in an 8-week online weight-loss intervention.
Randomization to MI groups with or without values discussion.
Measurement of weight, motivation, and qualitative analysis of self-motivational statements.

Main Results:

84% of participants found the format and topics acceptable.
No significant difference in self-motivational statements between groups (P=0.85).
Self-motivational statements correlated with increased autonomous motivation (r=0.58, P=0.05).
Higher autonomous motivation linked to greater weight loss (r=0.51, P<0.05).

Conclusions:

MI techniques are feasible and acceptable for online weight-loss interventions.
MI may enhance autonomous motivation, a key factor in successful weight management.
Further research is warranted to confirm MI's efficacy in digital weight-loss programs.
