We’ve often talked about the benefits of carbohydrate for runners, cyclists and triathletes, but for many people there’s an underlying concern - does eating all those carbs increase the risk of developing diabetes or heart disease? It’s certainly a common message that’s pushed online in some circles, but is this really the case?

In this episode I speak to diabetes researcher and clinical dietitian Dr Nicola Guess from the University of Oxford, who has often been asked this exact question by concerned runners, cyclists and triathletes. We break down what science tells us about the underlying cause of diabetes, how carbohydrate, exercise and body composition fit into the picture, whether high carb diets are a risk factor for chronic disease in their own right, and whether the approach should be different based on the level of training and fitness, age, family history, and existing health conditions.
