Overview

Background Obesity has detrimental personal, societal, and economic consequences and raises the risk of developing chronic diseases such as diabetes and cardiovascular diseases. Diet and exercise behaviors are frequently the focus of weight loss programs. Effective nutrition education is associated with a reduced risk of chronic diseases and body weight management. Individualized lifestyle and counseling sessions with follow-ups reduce weight loss compared to single combined sessions Objectives The objective of this study was to assess the effectiveness of nutrition education intervention on weight loss among adults aged 18-40 years in Lahore through an interventional study. Methods This study was conducted in Lahore. According to the inclusion criteria, overweight/obese (Body Mass Index (BMI) ≥ 23 kg/m²), young (18-40 years old) men and women were part of this study. A total of 50 participants were randomized into two groups, one as the control group and the other one as the intervention group. Group counseling was provided to the control group. The intervention group was assessed individually through follow-ups for 3 months of online and on-campus sessions. Data was collected at four intervals at baseline, month 1, month 2, and month 3 through a self-administered assessment form. Data was analyzed using the statistical package for social science, SPSS version 25 (IBM Corp., Armonk, USA). Results Out of the 50 participants, 54% (27) were women while 46% (23) were men (mean age 29.90, SD = 6.26, BMI at baseline 32.18 kg/m², 26. 49 kg/m²), and randomized by a blinded researcher. At three months, the mean differences in BMI, waist circumference, waist-to-hip ratio, and body fat percentage between the groups were 3 kg (23.44 ± 0.58, 95% CI 22.86-24.02), 33.90 cm (95% CI 32.50-35.30), 0.86 (95% CI 0.74-0.98), and 24.79% (95% CI 18.00-31.58), respectively, in favor of the intervention group (p < 0.005).  Conclusion This study demonstrates that a structured dietary intervention combined with physical activity guidance leads to significant weight loss and improved body composition in obese adults. These findings support the effectiveness of comprehensive weight loss strategies for managing obesity.
