## The short version, in writing

Topic: Hunger, nutrition, ultra-processed foods, food addiction, and metabolic health

Why do we eat when we aren't physically hungry? And is weight gain really just a matter of calories in versus calories out?

In this episode, Dr. Kwajo welcomes back Dr. Jason Fung, renowned physician and author of The Hunger Code , The Obesity Code , and The Diabetes Code , for a fascinating conversation about the complex factors that influence our eating behaviours and metabolic health.

Dr. Fung explains why hunger goes beyond physical needs, exploring the emotional and social influences that shape when, what, and why we eat. From the impact of ultra-processed foods to the role of habits, environmental cues, and food addiction, this conversation challenges conventional assumptions about nutrition and weight management.

They also discuss how hormones, insulin, stress, and sleep influence the body's use and storage of energy—and why understanding the reasons behind our eating habits may be an important step toward making meaningful changes.

Whether you're a healthcare professional or someone looking to better understand your relationship with food, this episode offers valuable perspectives on the science of hunger and the factors that shape our daily choices.

What You'll Learn in This Episode

- Why physical hunger is only one part of the eating equation.

- The three types of hunger discussed in The Hunger Code : homeostatic, hedonic, and conditioned hunger.

- How emotional states such as boredom and stress can influence eating.

- Why social settings and daily routines can trigger the urge to eat.

- How ultra-processed foods may encourage eating beyond physical hunger.

- The emerging discussion around food addiction and reward-driven eating.

- Why hormones, including insulin and cortisol, matter when examining metabolic health.

- How sleep, food choices, and environmental factors can influence our eating patterns.

- Why understanding why we eat can be just as important as understanding what we eat.

Dr. Fung shares where listeners can find his books, educational videos, and other resources.

Understanding our relationship with food requires more than looking at calories alone. Physical hunger, emotions, social expectations, habits, food environments, and hormones may all play a role in eating behaviour.

As Dr. Fung explains throughout the conversation, asking "Why am I eating?" can help us better understand the patterns that influence our choices.
