Fasting and the effect on Metabolic Syndrome

Type II diabetes

Arnason, T, Bowen, M, et al. Effects of Intermittent Fasting on Health Markers in Those with Type 2 Diabetes: A Pilot Study. World J Diabetes. 2017 Apr 15; 8(4):154-164. 8(4)154-64. PMID: 28465792

This pilot study tested the safety, and efficacy of daily intermittent fasting on diagnosed type II diabetics. The results indicated that it might be a safe, tolerable, dietary intervention which might improve critical outcomes such as body weight, fasting glucose and variability in blood glucose response to meals. These findings look promising.  However, the authors believe it should be viewed as exploratory, and a larger, longer study is necessary to corroborate these findings.

 Results of this study suggest that prolonged fasting is feasible and might have beneficial clinical effects with people suffering from Type II diabetes. The effectiveness of fasting should be proved in larger confirmatory trials that include intermittent fasting in follow-ups to enable more pronounced and long-term effects.
