If you’ve tried counting calories and still struggle with cravings or weight gain, this episode will change how you think about fat loss.
In this episode, I interview NY Times bestselling author Dr. Jason Fung about his new book “The Hunger Code.” In this interview, he explains why the calories-in, calories-out model is incomplete and often sets people up for failure. The real issue isn’t how much you eat — it’s why your body keeps pushing you to eat more.

The Fat Thermostat That Controls Hunger and Weight
In this episode, Dr. Fung introduces the concept of your body’s “fat thermostat,” a hormone-driven system that determines whether you store fat or burn it.
You’ll learn how insulin, cortisol, and other signals quietly raise or lower this thermostat, influencing hunger, cravings, and energy levels without you realizing it.

How Processed Foods Hijack Hunger Signals
Ultra-processed foods don’t just add calories — they disrupt the very systems that tell you when to stop eating.
Dr. Fung breaks down how food processing affects hormones, digestion speed, and satiety, making it easier to overeat while never feeling satisfied.

A Smarter, Sustainable Path to Fat Burning
Rather than relying on restriction, this conversation focuses on restoring balance. You’ll hear practical insights on food choices, meal timing, and simple habits that help calm hunger, improve metabolic flexibility, and support long-term fat loss without fighting your body. Be sure to check out Dr Fung’s new book “The Hunger Code.”
