Lies My Doctor Told Me: 8 Medical Myths Dr. Ken Berry Says Are Harming Your Health
I remember being a young mom, completely confused by the nutrition information available to me. 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.
Today I'm grateful to be part of a growing community of people who are questioning what they've been told, learning the truth, and passing it on. Every honest conversation moves the needle. That's how real change happens.
Dr. Ken Berry is a board-certified family physician who has been willing to do something rare in medicine: change his mind when the evidence demanded it. His book, Lies My Doctor Told Me, takes on the medical myths that have been repeated so long they became gospel. These aren't fringe ideas. They're things your doctor likely told you. And many of them have caused real harm.
Here's what he covers.
Eating Fat Will Make You Fat
It was never the fat. It was the sugar and the processed carbs. When fat got demonized, food companies replaced it with sugar and chemicals. Obesity rates followed. Natural fats found in meat, eggs, butter, and olive oil support hormone health, brain function, and satiety. They are not your enemy.
Red Meat Is Dangerous
This claim rests on weak observational studies, not hard science. Red meat is one of the most nutrient-dense foods available. Unprocessed, quality animal protein provides iron, B12, zinc, and essential amino acids your body requires. The data does not support the fear.
Whole Grains Are the Healthiest Carbs
Grains spike blood sugar, irritate the gut lining, and drive inflammation, particularly in people with insulin resistance. Whole grains are not essential. Many people feel significantly better without them.
Milk Is Necessary for Strong Bones
Bone health depends on vitamin D, magnesium, protein, and weight-bearing movement. Calcium from milk is a distant consideration. The dairy industry spent decades marketing this narrative. The science tells a different story.
Salt Causes High Blood Pressure
Sodium is a vital electrolyte. It regulates blood pressure, hydration, and nerve function. The real driver of hypertension is insulin resistance, not the salt on your food. Cutting sodium too low causes fatigue, dizziness, and electrolyte imbalance. The problem is ultra-processed food, not natural salt.
The Food Pyramid Is the Gold Standard
The food pyramid was shaped by grain and dairy industry lobbying, not nutritional science. Following it has contributed to rising rates of obesity, diabetes, and chronic illness. It was never designed to make you healthy.
Sun Exposure Is Dangerous
Avoiding the sun entirely has driven widespread vitamin D deficiency. Moderate sun exposure supports immune function, bone health, and mood. Responsible time in the sun is not a risk. It's necessary.
Hormone Replacement Therapy Is Too Risky
For years, women were told HRT carried risks so serious it should be avoided. That framing was overstated. Some women choose HRT and that is a valid personal decision.
My position is food first, always. Insulin resistance drives the hormonal disruption that makes menopause so difficult for many women. Address that through dietary change and the symptoms often shift significantly before any medication is considered. I managed my own menopause symptoms through low-carb eating, without HRT, without medication. I'm not saying that's the right path for everyone. I'm saying it should be the first conversation, not the last resort.
Why This Book Matters
Dr. Berry isn't afraid to admit he once gave the wrong advice. That kind of honesty is rare in medicine, and it's exactly what makes him credible. If you've ever followed the standard advice and felt worse for it, this book will give you context for why. It covers statins, fiber, thyroid disease, insulin resistance, gallbladder myths, and more.
