If there’s one thing I want you to take from this newsletter, it’s this:

Most people aren’t binge-eating, purging, drinking too much, or acting impulsively because they’re “broken.”

They’re living in bodies that can’t make or respond to GLP-1 — one of the most important hormones for impulse control, reward regulation, cravings, and feeling satisfied.

And I know this firsthand, because for many years I struggled with binge eating, purging, and addiction and was able to naturally turn it all around once I understood the biology behind my behavior. It wasn’t a willpower issue. It wasn’t a character flaw. It was a signaling problem.

And yes, I know that sounds dramatic.

But if you’ve ever lived through the chaos of binging, purging, compulsive overeating, or addiction… you already know it’s true. It rarely feels like a “choice.” It feels like a hijacking.

Let’s talk about why.

GLP-1: The Gut–Brain Link Nobody Talks About

GLP-1 is made in the gut (specifically your L-cells). Most people think its job is “blood sugar and appetite.” Nope — that’s just the surface. GLP-1 is one of the major hormonal messengers that tells the brain: I’m full

I’m safe.

I can slow down.

I don’t need the next hit of dopamine.

I don’t need to chase relief.

I don’t need to numb out.

And when your body can’t produce enough GLP-1 — or the receptors in your brain stop listening — everything changes. This is where binge eating, purging, addiction, and impulse-driven behaviors explode. Because this isn’t about food. It’s about signaling.

How Low GLP-1 Messes With Your Brain (and Your Behavior)

Here’s what actually happens in the brain when natural GLP-1 production or sensitivity is impaired:

1. The Hypothalamus (Hunger + Reward Regulation)

Low GLP-1 = your hypothalamus becomes louder for hunger and quieter for fullness. This sets you up for: binge episodes food noise obsessive thinking about food never feeling “done”

This isn’t weakness.

This is physiology.

2. The Brainstem (Your Internal Brakes)

GLP-1 normally slows you down — literally. It tells the brainstem that you can pause, breathe, and stop eating. When GLP-1 signaling is low, this area becomes less responsive.

That means:

• difficulty stopping once you start
• eating past fullness
• compulsions that feel like a runaway train

This is why binge/purge cycles feel trance-like.

Your brakes aren’t working.

3. The Mesolimbic Reward System (Addiction Center)

Here’s where it gets controversial. Low GLP-1 makes the reward system hypersensitive — the same system involved in drugs, alcohol, gambling, porn, shopping, sugar, and binge eating.

When GLP-1 is impaired:

• dopamine hits feel weaker
• cravings get louder
• you need more to feel the same effect
• impulsive behaviors increase
• addiction risk skyrockets

This is why a lot of people who aren’t “food addicts” suddenly feel addicted to food.

It’s a signaling problem — not a personality flaw.

4. The Prefrontal Cortex (Motivation + Executive Function)

GLP-1 increases motivation, focus, and the ability to follow through.

Low GLP-1 looks like:

• “I know what to do, but I can’t seem to do it”
• zero drive
• procrastination
• feeling emotionally flat
• low resilience

This is also why many people who optimize their GLP-1 suddenly say “I feel like myself again.”

Because they’re not fighting biology anymore.

Here’s the uncomfortable truth:

A lot of the behaviors people shame themselves for —

binging, purging, drinking, impulsivity, emotional eating —

have NOTHING to do with willpower.

They are the predictable outcome of a body not producing or responding to GLP-1 properly.

And most people don’t even know that’s what’s happening.

What Causes Low GLP-1 Production?

The short list:

• inflammation in the gut
• L-cell dysfunction
• low stomach acid
• poor bile flow
• circadian rhythm disruption
• chronic stress + high cortisol
• nutrient deficiencies
• endotoxins (LPS) blunting GLP-1 receptors
• late-night eating
• dysbiosis

Most people working through binge/purge cycles or addiction have multiple of these at play.

Again: not your fault.

But it is your biology.

So What Can You Do?

Here’s the part where you take your power back — not through force, but through physiology.

1. Fix the Gut So L-Cells Can Work

Your GLP-1 is made in the gut. If the gut is inflamed, leaky, or dysregulated, GLP-1 will be low — period.

Support:

• improve stomach acid
• reduce gut inflammation
• support bile flow
• increase fiber diversity
• remove inflammatory triggers

2. Repair Circadian Rhythm

GLP-1 follows a circadian rhythm.

It’s highest in the morning, lowest at night.

Support:

• morning sunlight
• breakfast with real protein (40g minimum)
• stop eating 2–3 hours before bed
• limit screens after dark

3. Support the Reward System

We can rebuild sensitivity.

• protein-first meals to stabilize dopamine
• strength training
• real carbohydrates from whole foods
• reduce alcohol and ultra-processed foods
• consistent sleep

4. Lower Inflammation + Endotoxin Load

Endotoxins blunt GLP-1 receptors.

This is why people with gut issues experience more addictive tendencies, binge cycles, and cravings.

Support:

• address dysbiosis
• address constipation
• support the liver + bile flow

5. Practice Nervous System Repair

Because impulsivity isn’t just chemical — it’s also survival.

• breathwork
• grounding
• cold exposure
• light exposure
• vagus nerve support

​

Final Thought

You can’t willpower your way out of a hijacked reward system.

But you can fix the imbalances in your body that drive these behaviors.

When the biology changes, the behaviors change.

Every single time.

This is what we do in my practice — we rebuild the internal environment so your brain and body finally work with you, not against you.
