Brain fog is a liar. It makes you feel like you're losing your edge, or worse, losing yourself. When you forget where you parked or struggle to find a word that's literally on the tip of your tongue, it’s easy to spiral. You start thinking about dementia. You start thinking about your parents. You start wondering if your brain is just... breaking. Will Mitchell’s book, The Unbreakable Brain, enters this specific, high-anxiety space with a premise that’s as bold as its title: you can protect your mind from the "shrinkage" we’ve been told is inevitable.
But is it legit?
Honestly, the world of "brain health" is a minefield of supplements, pseudoscience, and predatory marketing. You've probably seen the ads for pills that claim to turn you into a genius overnight. Mitchell, who isn't a medical doctor but a practitioner of Oriental medicine and a researcher, takes a different tack. He focuses on the biological "thieves" he claims are robbing us of our memories. He’s basically arguing that Alzheimer’s and general cognitive decline aren't just bad luck. They’re the result of specific, fixable physiological stressors.
Why The Unbreakable Brain focuses on inflammation
Most people think of inflammation as a swollen ankle. Mitchell wants you to think about your brain "swelling" in a much more subtle, chemical way. In The Unbreakable Brain, the core argument is that chronic inflammation is the primary driver of neurodegeneration. This isn't exactly a fringe theory. The medical community has been looking at the "amyloid cascade hypothesis" for decades, but Mitchell leans heavily into the idea that lifestyle interventions can stop this process before the damage becomes irreversible.
He identifies several "brain thieves."
One of the big ones? Sugar.
We’ve heard this before, but he frames it through the lens of Type 3 diabetes. This is a term some researchers use to describe Alzheimer’s because of how the brain becomes resistant to insulin. When your brain can't process fuel properly, cells start to wither. It’s a slow-motion starving of your neurons. Mitchell's approach in The Unbreakable Brain by Will Mitchell isn't just about cutting out donuts; it's about understanding how your blood sugar levels are directly linked to the physical size of your hippocampus.
The gut-brain connection is more than just a trend
You've probably noticed that every health influencer is talking about the microbiome lately. Mitchell was on this early. He talks about the "leaky brain" syndrome, which is essentially the sequel to leaky gut. If your intestinal wall is compromised, toxins enter the bloodstream. They eventually hit the blood-brain barrier. If that barrier gets "leaky," your brain's immune system—the microglia—goes into overdrive.
Think of microglia like a neighborhood watch that’s had way too much coffee. They start attacking everything, including healthy neurons.
- The Gut-Brain Axis: Mitchell suggests that fixing your digestion is a prerequisite for fixing your memory.
- Gluten and Casein: He identifies these as common triggers that might be causing silent inflammation in the brain for sensitive individuals.
- Probiotics: Not just for bloating, but for mood and cognitive clarity.
It's a holistic view. It's not just "take this vitamin." It's "change your internal ecosystem."
Statins and the cholesterol controversy
This is where Mitchell gets a bit controversial. In The Unbreakable Brain, he challenges the mainstream narrative regarding cholesterol. We’ve been conditioned to think cholesterol is the villain of every health story. But the brain is the fattest organ in the body. It’s literally made of the stuff. Mitchell argues that aggressively lowering cholesterol through statins might actually be starving the brain of the raw materials it needs to repair its own cell membranes.
He’s not telling people to throw away their prescriptions—and honestly, you should never do that without a doctor—but he is asking readers to look at the side effects of certain medications. If your brain needs cholesterol to build synapses, and you’re driving your levels down to near zero, what happens to your ability to form new memories? It’s a nuance that often gets lost in 15-minute doctor appointments.

Practical steps for an "unbreakable" mind
So, what does the protocol actually look like? It’s not just a list of "don'ts." It’s a specific way of living.
First, sleep is non-negotiable. During sleep, your brain uses something called the glymphatic system to wash out metabolic waste. If you don't sleep, the trash builds up. Imagine never taking the garbage out of your kitchen. Eventually, you can't cook anything. That’s your brain on six hours of sleep.
Second, Mitchell advocates for a high-fat, low-carb approach long before "Keto" was a household word. He focuses on "brain fats" like those found in wild-caught fish and avocados.
Third, he looks at heavy metals. This is a point of contention in mainstream medicine, but Mitchell points to the accumulation of things like aluminum and lead as potential catalysts for the plaques found in the brains of Alzheimer’s patients. He suggests specific chelation-style foods and supplements to help the body detoxify naturally.
- Stop the spikes: Use a glucose monitor if you have to, but get your blood sugar under control.
- Move your body: Exercise increases BDNF (Brain-Derived Neurotrophic Factor). Think of BDNF as Miracle-Gro for your brain cells.
- Check your meds: Talk to your doctor about whether your current prescriptions might be affecting your cognitive clarity.
The skepticism: What critics say
It's important to be honest here. The Unbreakable Brain isn't a peer-reviewed medical textbook. It's a health guide. Some doctors argue that Mitchell oversimplifies incredibly complex diseases. Alzheimer's is a "multifactorial" beast. While lifestyle matters, genetics (like the APOE4 gene) play a massive role that diet alone can't always overcome.
Also, the book is often sold through long-form sales pages that can feel a bit... "infomercial-y." That triggers red flags for a lot of people. However, if you strip away the marketing fluff, the core advice—reducing inflammation, stabilizing blood sugar, and prioritizing sleep—is fundamentally supported by modern neurobiology.

Actionable insights to start today
You don't need to buy every supplement Mitchell mentions to see a difference. You can start by making small, high-impact shifts in your daily routine.
Prioritize Deep Sleep: Aim for 7 to 9 hours. Use blackout curtains. Keep the room cool. This is your brain's cleaning cycle. Don't skip it.
Eat the Rainbow (The Real One): Focus on dark berries like blueberries and blackberries. These contain anthocyanins, which have been shown to cross the blood-brain barrier and provide direct antioxidant support to neurons.
Eliminate "Brain Thieves": Try a 30-day elimination of processed sugars and see if your "fog" lifts. Most people find that their afternoon slump disappears when they stop the glucose roller coaster.
Hydrate with Electrolytes: Your brain is mostly water. Even mild dehydration can cause significant shrinkage in brain volume and lead to immediate cognitive errors.
The Unbreakable Brain by Will Mitchell serves as a wake-up call. It reminds us that we aren't just passive observers of our own cognitive decline. Whether you agree with every one of his theories or not, the message is clear: your brain is an organ that requires specific maintenance. You can't run a Ferrari on low-grade fuel and never change the oil, then act surprised when the engine seizes at 50,000 miles.
Start treating your brain like the high-performance machine it actually is. Audit your diet for inflammatory triggers. Move your body to trigger growth factors. Give your mind the rest it requires. These aren't just "health tips"—they are the foundation of cognitive longevity.
