Low carb vs low fat diet for type 2 diabetes. Episode #348

Contrary to the long held contention that low fat diets are best for people with type 2 diabetes (DM2), the totality of current evidence suggests that low carb diets are at least as effective in ameliorating metabolic health in DM2. In fact, low carb seems to be somewhat
better, particularly in the short to medium term, although the evidence is of moderate certainty.
 
On this week’s episode Prof Hanno Pijl (@HannoPijl) and dr Esther van Zuuren (@Ezzoef) join Dr Aseem Malhotra (@DrAseemMalhotra) to discuss the most appropriate diet for
people with DM2
 
Hanno Pijl is an internist-endocrinologist and professor of Diabetology at the Leiden University Medical Center (LUMC) In Leiden, The Netherlands. He co-authored over 250 papers in peer reviewed scientific journals, primarily related to obesity and type 2 diabetes. He has been a member of the Dutch Health Council (standing committee on nutrition) from 2008-2016. He currently co-chairs the Dutch Innovation center for Lifestyle Medicine (www.nilg.eu), a joint effort of LUMC and the Dutch Organisation of Applied Science (TNO) focusing on lifestyle interventions in health care.
 
Esther van Zuuren is a dermatologist at the Leiden University Medical Centre, but apart from that and more relevant for now is that her expertise lies in Evidence Based Medicine. She has been with Cochrane for almost 20 years, has held the position of Key Editor and
Methods editor for Cochrane Skin group for several years and conducted over 30 systematic reviews on a wide variety of topics. Furthermore, she is member of the GRADE working group, is a Recommendations Editor for DynaMed Plus (clinical evidence-based reference tool for clinicians) and Associate Editor for Systematic Reviews for the British Journal of Dermatology
 
In our 20 min conversation we discuss
 
Efficacy of low fat versus low carb diets in the treatment of type 2 diabetes
The method of weighing the certainty of evidence we used in our systematic review
of the literature
Dietary recommendations for people with type 2 diabetes

Time to get real about childhood obesity with Dr Sandro Demaio. Episode #347

Did you know that the worldwide prevalence of obesity nearly tripled between 1975 and 2016? In 2016, more than 1.9 billion adults and more than 340 million children were classified as overweight
or obese. At the individual level and in our modern, obesogenic world, weight gain has become the norm—the biological and social path of least resistance.
On this week’s podcast, Dr Sandro Demaio (@SandroDemaio) joins BJSM’s Daniel Friedman (@ddfriedman) to discuss childhood obesity and public health nutrition policy.
After recently leaving his role as the WHO’s medical officer for NCDs and Nutrition, Sandro was appointed the CEO of EAT , a non-profit startup focused on food and sustainability. Formerly an Assistant Professor and Course Director at the University of Copenhagen’s School of Global Health, and a postdoctoral fellow at Harvard, Sandro regularly shares his knowledge and ideas at international conferences, universities and public events. He founded the PLOS Global Health Blog, NCDFREE and festival21, and is currently a bestselling author and TV host.

In this conversation, Sandro addresses the following topics:
       Our current state of obesity
       Policies needed to address childhood obesity
       Sugar-sweetened disease and the sugar tax
       Role of the clinician in addressing the obesity pandemic

Research imbalance: Sport and Exercise in Women versus Men. Episode #341

In this podcast Katie Marino speaks to Jack Forsyth.
Jacky Forsyth (@JackyForsyth) is a senior lecturer at Staffordshire University. She is a lead organiser of the Women in Sport and Exercise Conference. In this podcast Katie Marino (@krmarino1) speaks to Jacky about the difference in the amount of research done on exercise in women compared to exercise in men, and why we need to correct this imbalance. The research community needs to strengthen and promote research on women in sport and exercise, with the goal of optimising women’s athletic success and increase their participation rates.
The Women in Sport and Exercise Academic Network (WISEAN) is mentioned in the podcast. It is a research-orientated interdisciplinary group that focuses on: Generating high quality, impactful research into women in sport and exercise (WISE); Collaborating and sharing resources; Increasing the visibility of WISE issues and Research mentoring.
