The Effect of Intermittent Fasting and Caloric Restricted Diet on Diabetic Rats

Abstract

The present study was aimed to investigate the effect of intermittent fasting and caloric restricted diet (RD) for 8 weeks on diabetic rats. Forty-nine adult male albino rats were divided into two main groups; the first main group was fed only on basal diet and served as negative control group and the second main group: diabetic rats were induced by a single intra-peritoneal injection of freshly prepared STZ (60 mg/kg BW) then divided into 6 subgroups: Subgroup (1) was fed only on basal diet and was served as positive cont. Subgroup (2) was fed on RD only. Subgroups (3, 4) were fed on basal diet and were deprived of food except water from 5 p.m. to 8 a.m. twice a week and every other day, respectively. Subgroups (5, 6): were fed on RD and intermittent fasting twice a week and every other day, respectively. The results indicated that RD and intermittent fasting significantly decreased the final body weight, feed intake and body weight gain % values as compared to the positive control rats. Diabetic treated rats had significant increase (p<0.05) in insulin concentration and lower glucose levels as well as an improvement in liver functions and lipid profile as compared to the positive control group. Conclusion: the findings suggest that intermittent fasting and caloric restricted diet could have a potential role in managing diabetes.
