The purpose of this study was to compare weight control behaviour, eating habits, and health-related life habits accordingto degree of obesity among normal, overweight, and obese groups. Self-perception of weight and desire for weight controlin males (p<0.001) and females (p<0.001) varied among the three groups. Reasons (p<0.001), experience (p<0.01), andmethod of weight control (p<0.05) were different among the three female groups, whereas males did not show anydifferences. Intake of nutritional supplements in the male obese group was higher compared to other groups (p<0.01),whereas eating habits were not significantly different among the three groups for both males and females. Food habits scorefor intake of fruits, milk, and yogurt were higher in females than males (p<0.001). Correlation coefficients of food habitsscore and anthropometric measurements showed that hip circumference was negative for intake of fruits in males, whereasRBW and BMI were positive for food combination, intake of bean products, and fishes in females (p<0.05). Frequency andfitting exercise in the obese female group were lower than in the other groups (p<0.01). Therefore, proper nutritionaleducation for obese individuals is recommended proper self-perception of weight, good food habits, and regular exercise.
