Objective:-To investigate whether there is relationship between BMI and IQ among 16 to 18 years old females . Research Methods and Procedures:-Data were selected from 16 to 18 years old females in 3 high schools in Al-Hassa. Study sample consisted of 60 to 80 females, 20 selected randomly from each school included in the research. Each school population divided into strata according to the age group, also weight, scale, meter and selfadministered standardized IQ were used for collecting the data. Then their score were calculatedby administering IQ test and compared with BMItoassess their performance by using chi-square test. Results:-There is no significant relationship between IQ and BMI, so there is no difference if the student is ideal in weight, obese or underweight to get high scores in IQ. In addition, number of obese students have high IQ scores. Conclusion:-This study shown that the BMI of the sample which were included in the research not affect the IQ results . But there might be another factors which affect IQ other than BMI . Human brain is a great machine that needs 25% of oxygen, sugar and calories consumed by the body; it became clear that the process of thinking require most of them (1). Your brain cells need two times more energy than the other cells in your body. Neurons, the cells that communicate with each other, have a high demand for energy because they're always in a state of metabolic activity. Even during sleep, neurons are still at work repairing and rebuilding their own out structural components (2). As known, energy comes from glucose sugar thus from food.
