Back to Episodes411 The Neuroscience of Anxiety, Addiction, Over Eating, And How To Break The Habit Loop With Dr Jud Brewer
Description
I recently had a conversation with psychiatrist and neuroscientist Jud Brewer that stopped me in my tracks — not because it was abstract or inspirational, but because it finally explained something I've lived with for decades.
Even in long-term sobriety.
Even with years of self-work, therapy, meetings, journaling, and personal development.
That thing is anxiety — and more specifically, how anxiety quietly turns into habits like worrying, overthinking, scrolling, information hoarding, procrastinating, and self-judgment.
What Dr. Brewer helped me see is this:
Anxiety isn't a personal flaw. It's a learned habit loop.
And once I saw that clearly, everything changed.
Worry Is a Behavior — Not a Personality Trait
One of the most powerful reframes from our conversation was this:
Worry isn't just a feeling — it's something we do.
Anxiety shows up as a sensation in the body. Worry is the mental behavior we use to try to control that sensation.
And here's the trap: Worry feels productive. It feels like we're doing something. That tiny sense of relief is enough to reward the brain — which means the loop gets reinforced.
Anxiety → Worry → Temporary relief → Repeat
Over time, this becomes automatic. So automatic we don't even realize we're doing it.
That's the definition of a habit.
Why "Why Am I Like This?" Keeps Us Stuck
As someone in recovery, I'm very familiar with the idea of "getting to the root cause." Childhood trauma, identity, shame, conditioning — all of that matters.
But here's what surprised me:
Dr. Brewer says the "why" is often the least important part when it comes to changing anxiety.
Not because the past doesn't matter — but because focusing on why often keeps us stuck in our heads instead of helping us change what we're doing right now.
When anxiety hits, the more helpful question isn't:
"Why am I like this?"
It's:
"What am I getting from this behavior?"
That question shifts us from self-blame to curiosity — and curiosity is where real change begins.
The Default Mode Network (AKA: The Overthinking Machine)
We also talked about the brain's default mode network — the system that activates when we're not focused on a task.
This network lights up when we:
-
Worry about the future
-
Replay the past
-
Judge ourselves
-
Compare ourselves to others
-
Crave, resist, or ruminate
In other words: it's the "me, me, me" network.
When fear (an urge to act now) gets crossed with planning (thinking about the future), we get anxiety.
Anxiety doesn't help us act. It freezes us.
That's why so many high-achievers know exactly what to do — and still don't do it.
The Three Gears of Change (This Is the Part That Actually Helps)
Dr. Brewer's work focuses on a simple but profound process he calls the three gears:
⚙️ Gear 1: AwarenessNotice the behavior.
Worrying. Scrolling. Self-judging. Avoiding.
No fixing. No shaming. Just noticing.
If it's automatic, it'
