Many people were taught that food can be understood by numbers such as calories.
But calorie counting isn’t as scientific—or harmless—as it seems.
In my recent webinar, I explored when calorie counting is helpful and/or harmful and how it might keep you stuck in misguided patterns.
Whether you’re a clinician or someone healing your relationship with food, this talk will help you see things differently.

🧠 THE NEUROSCIENCE OF EATING PLEASURE 🍽️
New research from UC Berkeley has uncovered a fascinating connection between our brain chemistry and how we experience pleasure from food!
Scientists have discovered that a brain chemical called neurotensin plays a crucial role in our ability to enjoy eating. When neurotensin levels drop, the brain’s dopamine pleasure network gets disrupted, reducing the joy we get from meals.
The most interesting finding? For many people, long-term dietary patterns can actually reduce these pleasure signals in the brain. This means some individuals might continue eating out of habit or boredom rather than genuine enjoyment.
“Bringing back neurotensin seems to be very critical for preventing the loss of desire to consume high-calorie foods,” explains UC Berkeley professor Stephan Lammel. When researchers restored neurotensin levels, it normalized eating behavior and improved overall wellbeing.
This groundbreaking study, published in Nature, helps us understand that healthy eating isn’t just about what we eat, but about maintaining our brain’s natural ability to experience pleasure from food.
What’s your relationship with food pleasure? Have you noticed changes in how much you enjoy certain foods over time? Share your thoughts below! 👇
