Experts in this episode

This week’s show is an interview with Alice Coffey and Petra Hanson. Alice is a PhD student at the University of Warwick, UK in Global Sustainable Development. Her research is focused on sustainable diets, child health and health inequality.

Petra Hanson is a clinical research fellow at the University Hospital Coventry and Warwickshire NHS Trust in the UK. They are both members of The Warwick Obesity Network, an interdisciplinary team of academics and clinicians at the University of Warwick working on obesity interventions.

Together they wrote a literature review on the effects of intermittent fasting on weight loss, metabolic health and insulin resistance. They wanted to know, how effective intermittent fasting really is according to existing evidence. The studies they looked at was on people living with overweight, obesity or type 2 diabetes.


Why it is relevant?

Intermittent fasting is becoming a trendy topic for health optimisation. Reviews like Alics’s and Petra’s are very important as they build the foundation for new health recommendations and guidelines in the future.

We discuss their findings and what it means for diabetics and anyone interested in health optimisation. Let’s hear why and for which claims we currently do not have solid evidence.

Unfortunately, there is no evidence just yet for intermittent fasting in people with type 1 diabetes, purely because of the clinical worry of inducing hypoglycemia and ketoacedosis. Those are worries and they have not been confirmed by science. My personal experience with fasting is, that both hypoglcemia events and the risk of ketoacedosis are massively decreased. Yet, to achieve a successful fast for diabetics multiple skills are required such changing background insulin by oneself easily and quickly.

Have a listen to the episode and be the first one to know about potential health recommendations coming up for weight loss and diabetes management.
