2.3 Glucose tolerance test
Intra-peritoneal glucose tolerance test was carried out at baseline and at the end of the 8-week treatment protocol. After a fasting blood sample collection, glucose (2 g/kg i.p.) was injected in fasted rats (8-12 hours) followed by tail vein blood sampling at different time points. Blood glucose levels were measured using a glucometer LifeScan (Miltipas, CA, USA).
