What behaviors are important for successful weight maintenance?

Area of Science:

• Behavioral Science
• Obesity Research
• Health Psychology

Background:

• Weight maintenance remains a significant challenge following successful weight loss.
• Understanding behavioral factors is crucial for developing effective long-term weight management strategies.

Purpose of the Study:

• To identify and compare behavioral factors associated with successful versus unsuccessful weight maintenance in middle-aged adults.
• To investigate the roles of self-efficacy, stress, and self-monitoring in long-term weight control.

Main Methods:

• A one-year follow-up study of 90 middle-aged participants from a weight loss program.
• Classification into successful weight maintainers (SWM) and unsuccessful weight maintainers (USWM) based on 5% weight loss retention.
• Comparison of weight control practices, stress levels, obstacles, social support, and self-efficacy between SWM and USWM groups.

Main Results:

• Successful weight maintainers (SWM) achieved a mean initial weight loss of 12% and demonstrated improved eating regularity and increased physical activity with less associated stress.
• During follow-up, SWM exhibited significantly higher self-efficacy in weight measurement, dietary adherence, and record-keeping.
• SWM participants consistently measured their weight and maintained records more frequently than unsuccessful weight maintainers (USWM), who reported more stress related to weight measurement.

Conclusions:

• Substantial initial weight loss through increased physical activity is important for weight maintenance.
• High self-efficacy, regular self-monitoring (weighing and record-keeping), and managing stress are critical behavioral components for sustained weight control.
