Non-alcoholic fatty liver disease (NAFLD) is one of those health conditions that, while incredibly common, doesn’t often make it to our dinner-table conversations. But as a highly prevalent condition globally, understanding NAFLD becomes crucial not just for ourselves, but also to support our friends and family. Join me in Episode #281 as I sit down with Alan Flanagan, PhD for a deep dive on this topic.
“A relative reduction in the level of fat in the liver of up to 45% could be potentially achieved with a weight loss of 7% of initial body weight.”
Dr Alan Flanagan, PhD, is a renowned voice in the field of nutrition, holding an MSc and PhD from the University of Surrey. Beyond his academic achievements, Alan’s commitment to imparting impartial, evidence-based nutrition insights shines through his work as the founder of Alinea Nutrition and as Research Communication Officer for Sigma Nutrition. In today’s episode, Dr Flanagan offers his insight into the intricacies of NAFLD, leveraging his extensive knowledge to provide clarity on this widespread health condition.
“Individuals can still accumulate fat in the liver that is – relative to their body size – potentially not around the levels that we might currently diagnose fatty liver as, but still represents quite a high burden of triglycerides in the liver.”
Learn about the complexities of non-alcoholic fatty liver disease (NAFLD) as Dr Flanagan breaks down its definition, its prevalence, and its profound impact on metabolic health. Listeners will gain an understanding of the risk factors associated with NAFLD, its link to conditions like type 2 diabetes, and practical lifestyle and dietary interventions that can both prevent and potentially reverse its progression.
