Timing of Eating: Energetic Hypothesis (SNP32)

In the ongoing exploration of weight loss strategies, the timing of food intake has emerged as a fascinating area of study. While traditional advice often focuses on what we eat, growing evidence suggests that when we eat could also play a crucial role in weight management. This concept, known as chrononutrition, examines how our body’s internal clock influences the metabolic processes associated with food intake. Could adjusting meal times offer a new pathway to effective weight loss?

#526: Eating Rate, Food Texture & Satiation – Marlou Lasschuijt, PhD

Food science and behavior are intimately connected. One critical but often overlooked facet of this connection is food texture and its substantial impact on eating behavior and energy intake. Food texture encompasses characteristics such as hardness and structure. It categorizes food into liquids, semi-solids, and solids, each with a wide range of textures—from dry and crispy to elastic and more substantial. This classification deeply affects how we consume food. The time it takes to chew and swallow a food item can vary greatly based on its texture.

#498: The PROPEL Trial & Weight Loss Interventions in Primary Care – John Apolzan, PhD

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.

#460: Dr. Priya Sumithran – Body Fat Regulation, Pros & Cons of Weight Loss Interventions, and GLP-1 Receptor Agonists

In this episode, Dr. Priya Sumithran discusses this physiologic control of body mass, in addition to environmental and behavioural factors that make weight loss maintenance difficult. Dr. Sumithran also discusses what this means for setting weight loss targets, choosing the correct intervention, and looking to non-weight-centric approaches for certain individuals. We also discuss the evidence on GLP-1 receptor agonist drugs, such as Semaglutide, as a treatment for obesity.

#429: Kevin Hall, PhD & Stephan Guyenet, PhD – Carbohydrate-Insulin Model vs. Energy Balance Model

The pathogenesis of obesity is clearly complex. And the need to have a comprehensive model to explain this pathogenesis is important. One such model, termed the Energy Balance Model, has largely been the consensus paradigm of obesity scientists to this point. However, there are others who propose that this is not the correct model of obesity, but rather that obesity pathogenesis can be better explained by a model called the Carbohydrate-Insulin Model (CIM) of obesity.

#395: Prof. Carel Le Roux – Current Thinking in Obesity Treatment

Professor le Roux is an expert in metabolic medicine and is currently a Professor of Experimental Pathology, University College Dublin. He is recognised as a world leader in metabolism and obesity. Professor le Roux’s clinical focus is in the management of Type 2 diabetes, pre-diabetes, obesity, cardiovascular risk and other metabolic disorders. Professor Carel le Roux has been published extensively and currently holds a number of editorial roles for journals in his field including, Clinical Obesity and Surgery for Obesity and Related Diseases.

#391: Is There a Body Weight Set Point?: Models of Body Mass Regulation

In this episode Danny and Alan discuss the three primary models used to explain body mass regulation: 1) Set Point Model, 2) Settling Point Model, 3) Dual Intervention Model. They discuss the role of feedback systems, environment, behaviour, as well as discussing both the “thrifty gene hypothesis” and John Speakman’s “drifty gene hypothesis”.

#388: Consequences of Weight Stigma and Weight Bias

Danny & Alan discuss the current evidence on the health consequences and societal consequences of weight stigma and weigh bias. This includes implicit bias, explicit bias, and internalization of bias. What evidence do we currently have? And what questions remain unanswered?
