Obesity is a major public health concern linked to numerous chronic diseases. This study assessed the effectiveness of community-based physical activity programs in reducing obesity and promoting healthy behaviors among 1,500 adults in urban and peri-urban areas. Participants engaged in structured aerobic and resistance exercise programs, along with health education sessions, over 12 months. Outcomes measured included BMI, waist circumference, physical activity levels, and self-reported dietary habits. Results showed a significant reduction in BMI (from 29.8 ± 3.7 to 27.6 ± 3.2, p < 0.01), improved waist circumference, increased physical activity engagement, and healthier dietary patterns. Findings indicate that community-based physical activity programs are effective in obesity prevention and health promotion at the population level.
