Aim and Objectives: The aim of the study was to assess the effect of yoga practice on the blood glucose levels and body mass index (BMI) in pre-diabetic individuals.

Materials and Methods: Cases attending outpatient department of between age group 21–55 years under pre-diabetic category (n = 128) based on laboratory investigations and BMI were recruited. Participants were divided in to two groups, that is, group 1 (Pre-diabetics with yoga practice) and Group 2 (Pre-diabetics without yoga practice). Participants of Group 1 were advised to attend the yoga sessions for 180 days and blood glucose levels and BMI was assessed.

Results: In Group 1, the mean blood glucose level was gradually decreased from the beginning (121.57 mg/dl in Group 1 and 121.98 mg/dl in Group 2) to end of 180 days (89.32 mg/dl in Group 1% 105.65 mg/dl in Group 2). The mean BMI was significantly decreased from the beginning (27.63 in Group 1 and 27.24 in Group 2) to the end of 180 days (21.33 in Group 1 and 24.26 in Group 2) in both study groups. The mean difference of glucose levels and BMI among both study groups was statistically significant (P < 0.05).

Conclusion: Yoga practice was significantly reduced the BMI and blood glucose in pre-diabetic participants. However, the rate of decline in the levels of blood glucose and BMI was high in pre-diabetics under yoga practice. Continuous yoga adherence and healthy lifestyle practices can improve.
