The PROPEL (Promoting Successful Weight Loss in Primary Care in Louisiana) trial was a cluster-randomized weight loss trial is specifically tailored to address the pressing health concerns of an underserved population in Louisiana, where obesity rates have reached alarming levels. In this episode we have the opportunity to delve deeper into the intricacies of the PROPEL trial and gain insights from one of its lead researchers, Dr. John Apolzan of the Pennington Biomedical Research Center.
In this episode, we look to answer the question ‘do high protein diets cause insulin resistance or increase diabetes risk?’.
The management of type 2 diabetes has long been a challenge, but a new study conducted by researcher Mark Lyngbaek and his colleagues has the potential to add important considerations to the approach to treatment. Titled the “DOSE-EX” randomized clinical trial, their study uncovers the impact of exercise and weight loss on beta-cell function, a key factor in diabetes progression.
In the UK, there is a threefold higher incidence of type 2 diabetes in UK African and Caribbean (AfC) communities, compared to the general population. And ethnic inequalities in type 2 diabetes treatment and outcomes have been documented. Differences in outcomes relate to physiological differences as well as pragmatic issues and structural barriers. Professor Louise Goff has done pioneering work in relation to both aspects.
Introduction Peaks in blood glucose (or “blood sugar spikes”) are commonly highlighted as something harmful to health. And, of course, an excessively high blood glucose response to a meal can be problematic, or at least indicate there is a problem. However, elevations in blood glucose after eating are a normal physiological response. And “bad” blood glucose responses are those that stay high for a prolonged period; i.e. after elevating, they don’t return to normal within an appropriate period of time. But now many normoglycemic people are worrying about normal blood glucose responses, due to information that portrays even moderate elevations …
In this discussion with Dr. Nicola Guess, we discuss a range of topics related to glycemia, diabetes, and diet. This includes the potential for high-protein interventions, what utility CGMs actually have, what to make of diabetes remission trials, and future directions for the field.
In this episode we discuss the unique aspects of fructose metabolism, why some studies appear to show unique harm of fructose, and the implications of this for dietary choices.
In this episode, we look at three specific elements of this: average blood glucose, glucose variability, and glucose peaks. All in the context of people without prediabetes or type diabetes, who have typcial blood glucose measures in the ‘normal’ range.
In a situation where someone is not overconsuming calories or gaining weight, what health impacts do added sugars have?
Many different diets have been put forward as solutions that treat type 2 diabetes. Some will claim the diet “reverses” diabetes, some say it puts it into “remission”, while others more conservatively recommend a diet to manage diabetes symptoms in a healthy way.
There has been some debate on the use of terms like reversal, cure or resolution. And recently more clarity has been found in defining each.
One of the diets that has been recommended by some for the purposes of “reversing” or treating diabetes is a low-fat, whole food plant-based (WFPB) diet. Specifically, there is a claim that it is superior to other diets in treating diabetes. Some of these claims relate to popular online diet & lifestyle programs that use such a diet. While there is also a number of studies that are commonly cited in support of the claims.
In this episode, we evaluate these claims by looking at the published research in this area, across epidemiology, human intervention trials and mechanistic rationale. We also ponder what it means for something to be the “best” diet to treat a chronic disease.

He is an Honorary Academic for Public Health England Obesity and Healthy Weight Team, on the strategic council for APPG on Obesity and is on the scientific council of the British Nutrition Foundation.
In this episode we explore the causes of insulin resistance, and the dietary modifications that may help those with insulin resistance.
Guest InformationProf. Roy Taylor, MB ChB, MD Roy Taylor is Professor of Medicine and Metabolism at the University of Newcastle in the UK. There he is also director of the Newcastle Magnetic Resonance Centre. Prof. Taylor is an Honorary Consultant Physician at Newcastle Acute Hospitals NHS Trust. Since publishing his “twin cycle” hypothesis of type 2 diabetes in 2008, Prof. Taylor and colleagues have published several fascinating studies with potentially large implications for the potential to put diabetes into remission. Three of the most important trials were the Counterpoint Study, the Counterbalance study and the DiRECT study. All of which …
