The current study is a descriptive, interventional study, conducted at a governmental secondary school for girls to evaluate the different eating habits and attitudes of a sample of the school students, together with detection of their weight status. The NNI-eating behavior scale to reveal the different eating habits, EAT-26 for detecting the risk of developing eating disorders and anthropometric measurements were the main tools used.Our finding in the current study showed that, most of the studied sample were adopting unhealthy eating behavior and were at risk of developing an eating disorder. Calculating the BMI and its interpretation on CDC charts reflected high prevalence of obesity and overweight among the studied sample. Reassessment of the eating behavior following nutritional education sessions to a sub sample of overweight and underweight group; showed positive response of the overweight group who showed improvement in their eating habits unlike the underweight group who had negative response to the educational intervention. The study recommended that nutrition education should be mandated as a required and essential component of school health program. Training of specialized personnel, creating a healthy nutritional school environment and nutrition education for the students are all required to improve the nutritional status of the school students.
