Abstract This study examined the relationship between the impact of weight on quality of life, emotional appetite, and psychological well-being. The study included 124 obese individuals with a Body Mass Index (BMI) of more than 30 kg/m2, 129 overweight individuals with a BMI between 25-29.9 kg/m2 and 123 normal weight individuals with a BMI less than 25 kg/m2 who applied to certain nutrition and dietetics clinics in Istanbul. The Impact of Weight on Quality of Life Scale (IWQOL), Emotional Appetite Questionnaire (EAQ), and Psychological Well-Being Scale (PWS) were administered to the individuals. There was a significant positive correlation between the quality of life and psychological well-being scores in the normal BMI group. There was a significant positive correlation between quality of life, psychological well-being, and positive emotional appetite scores in the overweight BMI group. There was a negative correlation between psychological well-being and negative emotional appetite. There was a significant positive correlation between the quality of life and psychological well-being scores in the obese BMI group. In addition, the psychological well-being scores of those in the normal and overweight BMI groups were significantly higher than those in the obese BMI group were. The negative emotional appetite scores in the overweight and obese BMI groups were significantly higher than those in the normal BMI group. Those in the normal BMI group had significantly higher positive emotional appetite scores than those in the overweight BMI group did. These findings are discussed within the theoretical framework.
