Background:  Obesity and its associated disorders are a growing epidemic across the world. Many genetic, physiological, and behavioral factors play a role in the etiology of obesity which causes disturbance in energy equilibrium. Balance should be maintained between energy intake and its expenditure. This can be assessed by an individual’s basal metabolic rate (BMR). Aims & Objectives: To measure and correlate variations in basal metabolic rate in obese and non obese individuals. Materials and Method: 140 female subjects were grouped into 70 obese and 70 non obese categories. Anthropometric measurements like height, weight, BMI and waist circumference were recorded. Body fat percentage and BMR were measured using Omron HBF 306 body fat analyzer. Results and Conclusions: This study is done by random sampling with power > 80% and Level of significance being 5%. The present study shows statistically significant higher values of waist circumference, BMI and body fat percentage (p< 0.000) in obese. Basal metabolic rate (BMR) shows statistically significant higher values (p< 0.000) in obese. BMR showed positive correlation with body fat percentage and Body Mass Index (BMI).
