Did you know 1 in 3 women have a chronic hormonal condition?

Allara helps women understand their health without the guesswork.

Most women experience treating symptoms like stubborn weight, fatigue, and irregular cycles in silos with a fragmented care experience. But your body and your healthcare shouldn't work that way.

At Allara, they close the gap between symptoms and solutions with a unified clinical approach. Allara's care team, made up of medical leaders and expert registered dietitians, partner to devise a treatment plan using advanced diagnostic testing and each patient's unique health history to address what the body needs: optimizing metabolic markers, balancing hormones, or both simultaneously. Whether you’re managing PCOS, insulin resistance, thyroid conditions, perimenopause, or a complex overlap of concerns, Allara treats root causes instead of chasing individual symptoms.

Allara offers personalized, evidence-based care that evolves with you over time – all accessible virtually and covered by insurance. You'll work with an expert team throughout your journey, adjusting your plan as your body and needs change, so you can finally feel like yourself again.

Hi, this is Ray.

I once spent three years using a specific keyboard shortcut in my video editing software that was, quite frankly, inefficient. It involved a three-finger claw maneuver that would have made a crab proud. When the software updated and provided a single-key alternative, I thought, "Great! I’ll save so much time!"

But for the next month, every time I needed to make an edit, my hand would instinctively contort into that old, painful claw. My brain knew the new way was better, but my nervous system was committed to the old way. I wasn't struggling to learn; I was struggling to un-learn.

We talk about Acquisition as if the brain is an empty hard drive. But it’s not. It’s a garden that’s already full of weeds… old biases, outdated methods, and "wrong" facts that we learned years ago. Today, we’re looking at why "Proactive Interference" makes it so hard to change your mind, and how to use "Neuroplasticity" to overwrite the mental rust.

Proactive Interference: The "Ghost" in the Machine

The primary reason un-learning is so difficult is a phenomenon called Proactive Interference. This happens when your old memories interfere with your ability to retrieve new ones. Think of it like trying to write on a piece of paper that’s already covered in dark ink; the new words just get lost in the old ones.

According to a study in Nature Reviews Neuroscience, the brain is physically "lazy" (energy efficient). Once it has a paved neural highway for a task, it takes massive amounts of metabolic energy to "tear up the road" and pave a new one. Your brain doesn't want to learn a new way; it wants to use the old, reliable circuit it already built.

Strategy 1: The "Context Switch" Hack

Memory is highly tied to Context. If you try to learn a new habit in the exact same environment where you practiced the old one, your brain will automatically trigger the old "Save File."

To un-learn effectively, you need to change your surroundings.

• The Protocol: If you’re trying to un-learn a bad study habit (like reading while in bed), move to a completely different room or a library.

• The Science: Research on context-dependent memory shows that changing your physical environment "weakens" the trigger for the old habit, giving your new, fragile neural pathways a chance to take root without interference.

Strategy 2: Active "Interference" (The Overwrite)

You can't just "delete" a memory. The brain doesn't have a trash can. Instead, you have to Overwrite it through a process called Reconsolidation.

Every time you recall a memory, it becomes "labile" (changeable) for a short window of time. If you recall the old "wrong" way and immediately follow it with the new "correct" way, you are essentially updating the file.

• The Technique: Catch yourself doing the old habit. Don't just stop. Stop, acknowledge the old way, and then perform the new way three times in a row. This creates "Competitive Interference" that favors the newer, more frequently used path.

Strategy 3: The "Beginner's Mind" (Shaking the Etch-a-Sketch)

The most dangerous words in learning are "I already know this." When you think you know something, your brain enters "Filter Mode," only noticing things that confirm your existing (and potentially wrong) model.

To un-learn, you have to practice Intellectual Humility. * The Hack: Try to explain the "wrong" concept as if you were teaching it to a skeptic. This forces you to look for the "seams" in your own logic.

• The Science: A meta-analysis on conceptual change suggests that learners who actively seek out "Disconfirming Evidence" are much more likely to successfully update their mental models than those who just try to "add" new info on top of old myths.

Why I’m "Re-Learning" the Piano

I learned piano as a kid with terrible hand posture. I was "The Claw" once again. Now that I’m re-learning as an adult, I’ve had to spend the first three months doing nothing but scales with a penny balanced on the back of my hand.

I’m not learning "Music"; I’m un-learning "Muscle Memory." It is frustrating, slow, and feels like I’m moving backward. But I know that until I clear out the "Mental Rust" of my childhood habits, I’ll never hit the high-level Fluency I’m aiming for.

Your "Un-Learning" Protocol

1. Identify the Ghost: What is one "fact" or "method" you use that you know is outdated?

2. Change the Scenery: Practice the new version in a new location.

3. The "3-for-1" Rule: Every time you slip into the old habit, perform the new one 3 times immediately.

4. Seek the "No": Actively look for reasons why your current "Map" is wrong. Don't defend your knowledge; attack it.

Final Thought

The mark of a true "Extreme Learner" isn't how much they can remember, but how quickly they can forget what no longer serves them. Your brain is a living, changing organ. Don't let yesterday’s "certainty" become today’s "cage."

I’m off to go balance some pennies on my hands. It’s a thrilling Tuesday night over here at the Ray household.

Stay plastic and keep updating your maps.
