This community weight control program effectively reduced body weight and improved nutrition in adults. Participants showed significant decreases in body weight, blood pressure, and caloric intake, alongside improved dietary composition.

Area of Science:

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

Background:

  • Overweight and obesity stem from complex behavioral, environmental, and genetic factors.
  • Effective community-based interventions are crucial for managing weight and improving health outcomes.

Purpose of the Study:

  • To evaluate the efficacy of the TrymGym, a community-based, multi-dimensional lifestyle behavior change program.
  • To assess changes in nutritional, physiological, and physical activity (PA)-related psychological factors in overweight and obese adults.

Main Methods:

  • A 12-week program involving education and cognitive behavioral training for diet and PA.
  • Paired sample t-tests were used to analyze changes in body weight (BW), anthropometrics, blood pressure, caloric intake, and PA psychological factors.

  • Nutritional intake, including macronutrient and micronutrient consumption, was assessed before and after the intervention.

    • Main Results:

    • Significant reductions observed in body weight (3.6%), diastolic blood pressure (6.4%), waist (4.1%), and hip circumferences (5.7%).
    • Caloric intake decreased, with a shift towards lower fat and higher protein percentages.
    • Despite increased PA participation, a decrease in behavioral intention for future PA was noted; micronutrient intake remained suboptimal.

    Conclusions:

    • The community-based TrymGym program effectively improved body weight, anthropometric measurements, and nutritional intake in overweight and obese adults.
    • While the program enhanced PA participation, further strategies may be needed to sustain behavioral intention for physical activity.
    • The intervention demonstrated positive physiological and nutritional changes, highlighting its potential in weight management.
