Background: Controlling one's appetite is an important factor in helping obesepatients to stick to their diet plan.As appetite is controlled by acylated ghrelin so, targeting acylated ghrelin during diet regimen will be beneficial for obese patients. Purpose: The study's goal was to look into the effect of modified qigong breathing exercise on acylated ghrelin and hunger perception in obese patients.Methods: Sixty obese patients with class I obesity (BMI 30-34.9 kg/m²) of both sexes (thirty males and thirty females) participated in the study.They were selected from outpatient clinic of Faculty of Physical Therapy, Cairo University. All patients were randomly assigned into two groups of equal numbers. Group A received supervised modified qigong breathing exercise three times per week for twelve weeks and controlled diet. Group B received controlled diet onlyfor twelve weeks.Perception of hunger, plasma acylated ghrelin, body weight, body mass index (BMI), waist circumference (WC) and body shape index (ABSI) were measured before and after the study.Results: Statistical analysis showed significance decrease in body weight, BMI, WC and ABSI of both groups A and B. Percentage of decrease of body weight was 7.76 %, 2.49 %, BMI was 7.71%, 2.34%, WC was 11.59 %, 3.99 %and that of ABSI was 6.65%, 2.35%for both groups respectively.There was a significance difference in acylated ghrelin(AG) and hunger perception in favor of group A with percentage of decrease in AG in group A was 23.62% while percentage of increase in group B was4.61%
