WEIGHT REDUCTION THROUGH A FLEXIBLE DIETARY AND SLEEP INTERVENTION WITH MOTIVATIONAL REINFORCEMENT AMONG WOMEN WITH OBESITY: A PRE-EXPERIMENTAL TIME SERIES STUDY

Abstract

Background: Obesity is a growing global health concern influenced by complex interactions between dietary behavioral and metabolic factors while physical activity is commonly emphasized in weight management it's necessity in achieving weight loss remains debated particularly in populations with limited access to structured exercise. 

Methods: Pre-experimental (one group pretest-post-test design) study was conducted among 65 obese women to evaluate the effectiveness of structured lifestyle intervention focusing on dietary regulation and sleep optimization.  Body weight was measured at baseline and across three follow-up periods additional data on socio- demographic characteristics, clinical variables, and laboratory parameters were collected. Statistical analysis included repeated measured and ANOVA, independent sample t-test, and Pierson correlation.

Results: Significant reduction in mean by the way it was observed decreasing of from (88.64 5.66 kg) at baseline to (79.20 4.88 kg) at the final follow up  (P˂ value 0.001). Weight loss was consistent across participants with no significant difference observed according to age, party, constructive use, or gestational diabetes (P value 0.05). Sleep duration improved substantially however it was not directly associated with what you wait outcomes. significant inverse correlations were identified between body weight and both vitamin D (r=-0.420, p ˂ value 0.001) and TSH levels (r=0.562, p˂ 0.001). Menstrual cycle regularity was the only variable significant associated with weight outcomes (p=0.022). Findings demonstrate that a structured dietary and sleep-based intervention can achieve significant weight reduction independent of regular physical activity. These results highlight the potential of non-exercise centered approaches for weight management particularly in settings with limited opportunities for physical activity.

Conclusion: The flexible dietary on the sleep intervention with motivational reinforcement significantly improve weight management outcomes among women with obesity.
