Zunehmendes Alter, Übergewicht und Bewegungsmangel sind neben dem genetischen Background entscheidende Risikofaktoren für das Auftreten eines Diabetes mellitus Typ 2. Langfristig führt eine unzureichende Blutzuckereinstellung zusammen mit Bluthochdruck oder erhöhten Blutfetten zu einem deutlich erhöhten Risiko für Herzinfarkte, Schlaganfälle, Amputationen, Augen-, Nieren-, oder Nervenschäden bei den betroffenen Personen. Interventionsstudien haben gezeigt, dass eine Änderung des Lebensstils mit nachfolgender Reduktion des Körpergewichts zu Prävention einer Zuckerkrankheit aber auch Verbesserung der Blutzuckereinstellung bei bereits bestehendem Diabetes mellitus Typ 2 führen kann. Es gibt zahlreiche spezielle Diätinterventionen, denen allen gemeinsam ist, dass es nur wenig bis gar keine guten klinischen Studiendaten über deren Effektivität und Sicherheit bei Menschen mit Diabetes gibt. Eine populäre Diät ist das intermittierende Fasten, wo sich Esstage mit Fasttagen abwechseln. Der Einfluss einer derartigen Intervention auf die Blutzuckereinstellung aber auch die Sicherheit bei Menschen mit insulinbehandeltem Typ 2 Diabetes ist bisher noch nicht untersucht. In unserer Studie werden PatientInnen mit Diabetes mellitus Typ 2, die eine Insulintherapie benötigen, zufällig zur Gruppe, die intermittierendes Fasten betreibt oder aber der Kontrollgruppe zugeordnet. In der 3-monatigen Studie soll vor allem der Einfluss auf das Körpergewicht, die Körperzusammensetzung, die Blutzuckereinstellung, die notwendige Insulindosis, das Wohlbefinden, den Blutdruck aber auch die Gefahr für Unterzuckerungen erhoben werden.
Intermittent fasting, a dietary intervention of predefined fasting periods, has gained popularity in people trying to lose weight over the last years. For some people it is easier to follow a predefined fasting period, interrupted by a period of unrestricted eating as compared to a continuous caloric reduction. Overweight or obese people with type 2 diabetes are advised to reduce their body weight, however the task remains challenging. Particularly in those already injection insulin, it is unclear, if fasting intervention are safe or if they put people at an increased risk of low glucose values (hypoglycaemia). The aim of our study was to investigate the impact of a 12-week intermittent fasting (IF) regimen compared with usual care in people with type 2 diabetes mellitus receiving insulin therapy. People in the intermittent fasting group were asked to eat on 3 days a week (Monday, Wednesday, Friday) at maximum 500 kcal until lunch time, followed by a fasting period until next day in the morning (they could have unsweetened drinks). On the other days of the week, they were allowed to eat without restrictions. The control group was asked to continue with their usual lifestyle. The study lasted for 12 weeks. Forty-six people with a mean body mass index of 34.34.5 kg/m2 and a mean HbA1c of 6711 mmol/mol were randomized to either the IF or control group. Dietary counselling and continuous glucose monitoring was provided. Within the 12 weeks, HbA1c was significantly reduced in the IF group (-7.3 12.0 mmol/mol) compared with the control group (0.1 6.1 mmol/mol) (p=0.012), as was the body weight (-4.774.99 kg in the IF group compared to +0.27 1.34 kg in the usual care group (p<0.001)). 40% of people in the IF group were able to reduce their body weight by at least 2%, to reduce their insulin dose reduction by at least 10% and to reduce HbA1c by at least 3 mmol/mol, while no participant in the control group managed to improve all three parameters. No severe hypoglycemia occurred. Hence, we believe that Intermittent fasting is a safe and feasible dietary option to ameliorate glycaemic control while reducing total daily insulin dose and body weight in insulin -treated people with type 2 diabetes.
