Continuous Engagement in a Weight-Loss Program Promotes Sustained Significant Weight Loss

Area of Science:

• Obesity and Weight Management
• Public Health Interventions
• Behavioral Science

Background:

• Significant weight loss is crucial for improving health outcomes.
• Weight regain remains a common challenge following initial weight loss efforts.
• Peer-led, low-cost programs offer accessible weight management solutions.

Purpose of the Study:

• To evaluate the long-term effectiveness of the Take Off Pounds Sensibly (TOPS) program.
• To determine if members achieved and maintained significant weight loss over seven consecutive years.
• To analyze weight change patterns within a large, national weight-loss program.

Main Methods:

• Retrospective cohort study design.
• Analysis of 2,346 members with 7 consecutive annual renewals.
• Categorization of weight change: significant loss (≥5%), weight stable (0-5% loss), and weight gain.

Main Results:

• 51% of participants maintained significant weight loss throughout the 7-year study period.
• 18% achieved significant weight loss initially but transitioned to other categories later.
• 25% remained in the weight-stable category, and 7% experienced weight gain by year 7.

Conclusions:

• Over 60% of TOPS members achieved significant weight loss by year 7.
• Continuous, long-term engagement in weight-loss programs promotes sustained results.
• Encouraging participation is vital, even for individuals not achieving immediate significant weight loss.
