The same results were yielded for knowledge of fibre-rich food, recommended daily intake of fruits, and recommended daily intake of breads and cereals, which also had insignificant results in the Chi-square. The knowledge items which yielded a significant result in the Chi-square include recommended intake for various sources and reading labels. Health Behaviours Examining the t-test results, most health behaviours prove to be significant. On the number of glasses consumed daily, the normal weight group had a higher average, indicating greater consumption. On the consideration of health in choice of food, there is no significant difference between the two groups. The same trend is observed on the time of taking supper. For time of sleeping, the obese group seems to sleep at a later time. Moreover, the normal weight group has a higher frequency of exercise sessions. The obese group also has more frequent intake of meals; crisps; sweets, chocolate or desert; sweetie beverages; low calorie drinks; instant noodles; and deep fried food. No such difference was noted between the two groups for frequency of eating snacks.
