The Nutritional status and prevalence of obesity were studied among students, who represent an important segment of the population of the Arab Republic of Egypt. The study was carried out on a random sample of 120 (60 male and 60 female) students. The age of sample ranged between (17-19) years old. Results showed that percentages of obesity and overweight in male (50%) and in female (45%). Energy and other nutrients intake of obese students in male and female are significantly higher than those for non- obese students. From the results obtained it was found that prevalence of severe deficiency among non-obese male and female was very clear. There was a relationship between obesity and food intake between meals. Results of biochemical investigations, showed significant decrease (P <0.05) in the mean value of total serum cholesterol and triglycerides in non-obese females in comparison to non-obese males. However, there were insignificant differences as regard to other studied parameters
