Lies My Doctor Told Me: 8 Medical Myths Dr. Ken Berry Says Are Harming Your Health
In Lies My Doctor Told Me, Dr. Ken Berry, a board-certified family physician, confronts widespread medical myths that have persisted in healthcare. Drawing from his personal journey and clinical experience, Dr. Berry reveals how certain long-held beliefs may not only be outdated but potentially detrimental to our health.
I personally believe that knowledge is power. The more you know, the more informed decisions you can make for yourself and your family. Dr. Berry is one of many physicians who has come to some powerful realizations over the course of his medical practice—realizations driven not just by science, but by personal experience. He represents what I think of as an “awakening” within the medical community. Every day, I come across more doctors who are challenging the status quo and exposing the misinformation that’s been blindly accepted for decades.
I remember being a young mom, constantly confused by the nutrition information available. It was either too complicated, totally conflicting, or if I tried to follow it—I ended up gaining weight and feeling worse. Nothing made sense. I wish I had known then what I know now.
Today, I’m grateful to be even a small part of this growing community of people who are questioning, learning, and sharing. Every time I pass along what I learn to a friend or a family member, I feel like it matters. That’s how real change happens—one honest conversation at a time.
Now, back to Dr. Berry’s book.
The Lies We’ve Been Told — And Why They Matter
Dr. Berry doesn’t just make claims—he backs them up with research, clinical outcomes, and common sense. Below are some of the most damaging medical myths he exposes in Lies My Doctor Told Me. These are things many of us were told to believe without question—and we’ve suffered for it.
❌ Lie #1: Eating Fat Will Make You Fat
We’ve been warned about fat for decades. “Low-fat” everything filled grocery shelves. But the truth? It was never the fat making us fat—it was the sugar and processed carbs.
Dr. Berry explains that healthy fats (like those found in meat, eggs, butter, and olive oil) are essential for hormone health, brain function, and satiety. When fat was demonized, food companies replaced it with sugar and chemicals—and obesity rates soared.
🟢 Truth: Natural fats are not your enemy. Sugar and ultra-processed carbs are.
❌ Lie #2: Red Meat Is Dangerous
For years, we’ve been told that eating red meat leads to heart disease and cancer. But if you look at the actual data—not the headlines—you’ll see this is based on weak observational studies, not hard science.
Dr. Berry dives into the historical and nutritional value of red meat, explaining how it’s one of the most nutrient-dense foods on the planet. Grass-fed beef, liver, and other animal-based proteins provide everything from iron and B12 to zinc and essential amino acids.
🟢 Truth: Red meat is not only safe—it’s incredibly nourishing when it’s unprocessed and from healthy animals.
❌ Lie #3: Whole Grains Are the Healthiest Carbs
“Eat your whole grains.” Sound familiar? The food pyramid made them the foundation of our diet. But modern wheat isn’t the wheat of our grandparents’ generation. It’s been hybridized and processed in ways our bodies don’t tolerate well.
Dr. Berry explains how grains spike blood sugar, irritate the gut lining, and often contribute to inflammation, especially in people with insulin resistance, autoimmune issues, or digestive disorders.
🟢 Truth: Whole grains are not essential. Many people thrive when they eliminate them.
❌ Lie #4: Milk Is Necessary for Strong Bones
The dairy industry spent billions convincing us that milk = strong bones. But many adults don’t digest dairy well, and there are better sources of calcium and bone-supporting nutrients.
Dr. Berry highlights that vitamin D, magnesium, and weight-bearing exercise are far more critical for bone health than chugging milk.
🟢 Truth: Bone health is about much more than calcium from milk.
❌ Lie #5: Salt Causes High Blood Pressure
“Cut the salt!” That was standard advice for years. But Dr. Berry explains how sodium is a vital electrolyte that helps regulate blood pressure, hydration, and nerve function. For many people, cutting salt too low actually makes things worse—leading to fatigue, dizziness, and electrolyte imbalances.
The real issue? Again—processed foods. Not natural sea salt.
🟢 Truth: Most healthy people don’t need to fear salt. The problem is ultra-processed food, not the shaker on your table.
❌ Lie #6: The Food Pyramid Is the Gold Standard
Dr. Berry exposes the food pyramid for what it is: a product of politics, lobbying, and corporate interests—not nutritional science. It was never designed to help people be healthy—it was built to sell products.
He walks you through how government guidelines have been shaped by grain and dairy industries, and how following them has only led to more obesity, diabetes, and chronic illness.
🟢 Truth: You don’t need a government chart to tell you what real food is. Look at what your great-grandparents ate—and start there.
❌ Lie #7: Sun Exposure Is Dangerous
Yes, too much sun without protection can cause skin damage. But fearing the sun entirely has led to widespread vitamin D deficiency. Dr. Berry stresses the importance of moderate sun exposure to support immune function, bone health, and mood.
🟢 Truth: Responsible sun exposure is healthy and necessary. We were designed to live under the sun—not avoid it.
❌ Lie #8: Hormone Replacement Therapy Is Too Risky
For years, women were told to avoid hormone therapy during menopause due to risks that were exaggerated or misunderstood. Dr. Berry encourages readers to revisit this topic with open minds and individualized care.
🟢 Truth: Hormone therapy may be safe and helpful when managed properly—it’s not a one-size-fits-all risk.
Why This Book Matters
This book isn’t about fear. It’s about freedom. Freedom from outdated beliefs that never served us. Freedom from chronic symptoms we thought were normal. And freedom to ask better questions and demand better answers.
Dr. Berry’s honesty is refreshing. He isn’t afraid to admit that he once gave the wrong advice—and that’s what makes him credible. He changed his mind when the evidence demanded it. That’s the mark of real integrity.
If you’ve ever felt confused by the conflicting health advice out there, this book will give you clarity. If you’ve struggled with your weight, your energy, your labs—this book is a wake-up call. And if you’ve ever trusted your doctor, only to feel worse—this book is validation that you’re not crazy. You were just misled.
📚 There’s Even More Inside the Book
What I’ve shared here are just a few of the medical myths Dr. Ken Berry breaks down in Lies My Doctor Told Me—but the truth is, this book goes much deeper.
There are chapters on statins, fiber, thyroid disease, insulin resistance, gallbladder myths, and so much more. Each section is packed with research, personal insights from Dr. Berry’s clinical experience, and information that challenges everything we thought we knew about health and nutrition.
I truly believe that anyone serious about their health should read this book. It’s not just informative—it’s empowering. Whether you’re just beginning to question mainstream advice or you've been down this road for years, Lies My Doctor Told Me will open your eyes.
You can find the book on Amazon and other major retailers. It’s available in paperback, Kindle, and audiobook formats, so however you prefer to learn, it’s easy to access.
Read it. Highlight it. Share it. Because the more we know, the more we can help ourselves—and each other.
If this post helped you—or made you think—please share it with someone you care about. That’s how change spreads. That’s how we take our health back.
