Fasting has gained immense popularity as a dietary approach, but what does the scientific evidence say about its health benefits?
#540: How Can We Improve Body Image and Self-Esteem Without Physique Change? – Gabrielle Fundaro, PhD & Eric Trexler, PhD
Body image and self-worth are deeply intertwined concepts that influence how we see ourselves and interact with the world. Many people believe that changing their physique is the key to improving their body image, but is it really that simple? This connection between appearance and self-esteem raises important questions about how we define confidence and whether our sense of worth should be tied to how we look.
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?
#520: How Exercise Impacts Appetite, Food Intake and Adiposity – James Dorling, PhD
In this episode, Dr. James Dorling of the University of Glasgow helps us delve into the evidence surrounding how factors like adiposity, sex, and habitual physical activity modulate our responses to exercise in terms of appetite, energy intake, and appetite-related hormone responses.

#510: Social Comparison: Evidence on its Impacts & What We Can Do – Shannon Beer
Social comparison theory, developed by psychologist Leon Festinger in the 1950s, posits that individuals determine their own social and personal worth based on how they stack up against others. This theory suggests that people engage in social comparisons to evaluate their abilities, opinions, and attributes, often choosing relevant others for comparison.

#484: Is Metabolic Adaptation an Illusion? – Eric Trexler, PhD
Some people have framed metabolic adaptation as so significant that it makes weight loss attempts futile. While others, including in research, have referred to metabolic adaptation as an “illusion”. So what do we actually know about this concept and what is the pragmatic significance of it? To discuss the nuances of the topic, Alan and Danny are joined by Dr. Eric Trexler, who has published on this topic and has followed recent publications closely.

#454: Eric Helms, PhD – Plant or Animal Protein: Rethinking Protein & Muscle
In this episode we explore some important points that are often neglected. Is MPS as reliable as we assume? Does the amino acid profile tell us everything about the anabolic effect of a protein? Does dose and timing matter as much as we think? How does the picture change when we look at whole foods or mixed meals?
#452: Stuart Phillips, PhD – Bacterially Synthesized Whey, Plant vs. Animal Proteins, Muscle & Extended Fasts, & Much More
In this episode Prof. Stu Phillips takes questions about synethized whey protein, plant proteins, post-exercise MPS, and many other topics related to protein, muscle function and ageing.
SNP8: “Calories In, Calories Out is Stupid” – Quack Asylum
One passionately debated concept is that of “calories-in, calories-out” (CICO). This is colloquial phrasing for how energy balance relates to bodily energy stores. And this gets translated as shorthand for indicating how energy balance influences gain/loss of body mass.
When looking at some of the commentary related to CICO, there are two opposing positions that are both incorrect. On one hand you have people who clearly focus too heavily on calories alone. But on the other you have people claiming that “CICO is wrong” and that looking at energy balance as the main driver of changes in body mass is misguided.
In this episode, we focus in on the latter of those positions, i.e. the claim that “CICO is a myth”, or “calories don’t matter” or “fat loss has nothing to do with CICO” or several other similar statements that we’ll look at one by one.
