Intermittent fasting could benefit people living with type 2 diabetes
Harald Sourij, lead study author and Professor and Head of the Trials Unit for Interdisciplinary Metabolic Medicine and Deputy Head of the Clinical Division of Endocrinology and Diabetology at the Medical University of Graz, said: “The average sugar levels improved significantly in the fasting group. In addition, the subjects lost an average of just under five kilograms of body weight.
“In contrast, blood glucose and weight levels remained largely unchanged in the control group.”
“It was paramount for us that we were unable to detect severe hypoglycaemia (low blood glucose levels in any of the test subjects. We now know how to adjust insulin dosage and that it is safe.”
Professor Sourij added: “Weight reduction plays an essential role in the treatment of type 2 diabetes. Very often, losing weight can lead to an improvement in the glucose metabolism.
“We were interested in knowing whether this type of dietary intervention works and is also safe for patients with diabetes who are already injecting insulin.
“Critics of this form of dieting often express the fear that people following the diet might develop a dangerous hypoglycaemia on fasting days.”
The researchers are now planning a follow-up study which will include exercise as a factor.
Professor Sourij said: “We want to investigate how weight loss from intermittent fasting can be fostered further by exercise – and how exercise affects not just sugar and insulin levels, but also the motivation of people with type 2 diabetes.”
