The present study is observational (correlational study). The title of the study is ‘Correlation of Obesity with Cognition, Metacognition and Academic Performance in School Going Adolescents’. The purpose of the study is to find out if obesity is correlated with cognition, metacognition and academic performance in school going adolescents in south east Asian population. There is a relative dearth of research specifically focusing on cognition and metacognition in relation to obesity in adolescents. More research is needed to explore how obesity may specifically affect metacognitive abilities and the potential implications for academic performance and self-regulated learning. The procedure involves selection of adolescents aged 13-17 years meeting inclusion criterion of BMI> 30. The sampling method is convenience sampling. The cognition of subjects is assessed by Stroop Word and Color test. The subject’s task is to look at each sheet and move down the columns, reading words or naming the ink color as quickly as possible, within given time limit (45 seconds). Three scores, as well as an interference score are generated using the number of items completed on page, with higher scores reflecting better performance and less interference on reading ability.  The metacognition is checked by Metacognition awareness inventory where students will fill the questionnaire. Academic performance record is collected as average percentage of last 2 Examination with teacher assistance. Data will be recorded and analyzed.
