Debunking Nutrition Myths: What Nina Teicholz and Nick Norwitz Are Revealing About Red Meat, Saturated Fat, and the Carnivore Diet
For years, we’ve been told to fear saturated fat, avoid red meat, and load up on grains and fiber. Government guidelines have pushed this narrative hard since the 1980s. But what if that advice was never grounded in solid science?
Nina Teicholz—journalist, researcher, and author of The Big Fat Surprise—has been on the front lines of exposing the shaky foundations of our dietary guidelines. She’s not afraid to ask the hard questions or go against the mainstream. And now, new peer-reviewed research is catching up with what she’s been saying all along: low-carb and meat-based diets are not only safe but may be the key to reversing chronic disease.
Let’s break it down in simple terms.
1. Saturated Fat Is Not the Villain
One of Nina’s biggest critiques is the long-standing war on saturated fat. We were told that butter, cheese, eggs, and red meat clog our arteries. But decades of science show the opposite.
New research she helped publish reveals that low-carb diets—often high in saturated fat—can improve heart disease markers. This includes:
Lowering triglycerides
Raising HDL (the “good” cholesterol)
Reducing blood pressure and inflammation
Saturated fat, in the context of a low-carb, whole-food diet, is not harmful. The danger lies in processed carbs and seed oils—not steak or eggs.
2. The Dietary Guidelines Are Failing Us
Nina’s organization, The Nutrition Coalition, has called out the Dietary Guidelines for Americans for lacking transparency and scientific rigor. Despite rising obesity, diabetes, and heart disease, the guidelines haven’t changed their tune.
What Nina is showing the world is that the evidence used to support low-fat, high-carb recommendations is outdated, biased, and in many cases, cherry-picked. It’s time we shift focus toward real, nutrient-dense foods—many of which were wrongly demonized.
3. Meat-Based Diets Are Not Dangerous
Here’s where Nick Norwitz steps in. A Harvard PhD student and metabolic health researcher, Nick has been speaking out about the misconceptions surrounding the carnivore diet—a way of eating that focuses on animal products and eliminates plant foods.
According to Nick, many people experience relief from autoimmune issues, chronic pain, and gut problems when switching to a carnivore diet. He argues that meat is one of the most nutrient-dense foods on the planet, containing everything the human body needs to thrive.
Nick helps dismantle claims that a carnivore diet leads to heart disease or cancer. The real threat? Ultra-processed foods, sugar, and industrial seed oils. Not ribeye.
4. The Fiber Myth
Both Nina and Nick have addressed the fiber myth—another idea that’s been accepted without challenge. While fiber can be helpful for some, it’s not an essential nutrient. Many people find improved digestion and less bloating when they cut back on fiber, especially from grains and legumes.
I can personally confirm this. After 8 years on a ketogenic lifestyle, I’ve never had digestive issues despite eating very little fiber. What I do eat is nutrient-dense, real food—mainly meat, eggs, seafood, and healthy fats.
5. Let’s Focus on What Works
The big takeaway? We need to rethink everything we’ve been taught about food.
Low-carb, meat-inclusive diets aren’t fringe anymore—they’re backed by science and lived experience. Nina Teicholz and Nick Norwitz are helping bring these facts to light, and it’s up to us to question, learn, and reclaim our health.
